BDO

1, 4-Butanediol (BDO)

FEATURES

    Butanediol is produced by hydroformylation & hydrogenation of Allyl Alcohol, carbon monoxide and hydrogen. 1,4-Butanediol is a colorless, high-boiling liquid with a low order of toxicity.

APPLICATION

Tetrahydrofuran (THF) & Polytetramethylene-Ether-Glycol (PTMEG).
    THF is the largest use for BDO and approximately 79% of THF consumption is for the production of PTMEG, which in turn is used in the manufacture of cast and thermoplastic urethane elastomers, polyurethane fibers (spandex) and
high-performance copolyester-ether elastomers. The remaining 21% of THF consumption is for use as a solvent in the manufacture of polyvinyl chloride cements and coatings, in precision magnetic tape and as a reaction solvent in the production of pharmaceuticals.

γ-Butyrolactone (GBL).
   
BDO is used as raw material for the manufacture of GBL. About 65% of GBL consumption is for the ma nufacture of N-methyl-2-pyrrolidone (NMP), which in turn is used as a solvent in lube oil extraction, electronics applications, paint strippers, magnetic wire coatings and engineering resins. About 25% of GBL consumption is used in the manufacture of 2-pyrrolidone/N-vinyl-2-pyrrolidone/polyvinylpyrrolidone, which in turn is used in the production of copolymers; in consumer and pharmaceutical applications, including cosmetics, hair sprays, germicides and tablet binders; in the paper, textile and agricultural industries; and in miscellaneous applications, such as process aids in beverage clarification. The remaining 10% of GBL is consumed primarily as an agricultural solvent and for lithographic use in photography.

Thermoplastic Polyesters.    
    BDO is used to manufacture polybutylene terephthalate (PBT). PBT's high strength, excellent thermal stability and good durability lead to its many uses in the automotive, electrical and appliance industries. PBT is also compatible with several other thermoplastics with several other thermoplastics which enables a compounder to tailor a polymer alloy to an end user's specifications.

Polyesters.
   
In polyurethane applications, BDO is primarily used as a component of polyesters or as a chain extender. For example, polyesters such as poly (butylene adipate) diols are formulated into urethane elastomers with excellent oil, chemical and UV resistance. In addition, these materials have good mechanical properties over a broad temperature range, as well as good flex and abrasion resistance.

Polyester Plasticizers.
   
BDO based polyester plasticizers impart superior compatibility with vinyl polymers while providing non-migrating characteristics. In addition, polyesters based upon BDO have excellent oxidation resistance and good low temperature flexibility.

Chain Extender with MDI Systems.
  
  As a chain extender, BDO provides a good balance between hardness and low temperature flexibility. On comparison to other diols, BDO combines the best attributes of hydroxyl reactivity, linearity and overall system compatibility to build in the proper crystallinity required in the polyurethane hard segment. Also, the BDO/MDI systems
provide a lower exposure hazard than MOCA/TDI systems.

Cast Urethane Elastomers.
   
This application continues to be a major end use of BDO because of overall consistency and reliability.

Urethane RIM Elastomers.
    This application using BDO allows design freedom and parts consolidation with large, complex shapes.

Urethane Elastomers.
    The current applications of BDO based urethane elastomers include automotive front and rear end fascia, bumpers, fenders and spoilers. Non-automotive applications include footwear, electrical enclosures, recreation equipment, appliances and furniture.

Copolyester Hot Melt and Solvent Borne Adhesives
    BDO is a key component of copolyesters of isophthalic acid and terephthalic acid used in hot melt adhesive applications. BDO yields polyesters with excellent adhesive and cohesive strength.

Storage and Handling
    In the presence of strong acids, BDO is dehydrated to THF. Keep away from heat, sparks, and flame. Since BDO solidifies at temperatures below 19℃, appropriate storage temperatures are required; however, reliquidation does not alter its properties. BDO can be shipped and stored in mild steel; however, coated tanks or stainless steel will prolong.

MPO

2-Methyl-1,3-Propanediol (MPO)

FEATURES
 

Methyl-Propanediol is a by-product which is produced by hybroformylation, hydorgenation of Allyl Alcohol, carbon monoxide and hydrogen. It is a colorless, low viscosity and toxicity liquid with a unique molecular structure - a branched aliphatic diol with two primary hydroxyls.

APPLICATION

Unsatured Polyester Resins (Composites).
    The unique molecular structure of MPO brings significant process and property advantages to unsatured polyester resins. The all-primary hydroxyl and high boiling point character of MPO increase both esterification rates and kettle productivity. This higher reactivity compared with other glycols, such as propylene glycol, leads to lighter color resins. Also, the non-linear backbone of MPO provides polyester with excellent styrene miscilility. MPO provides an excellent balance of tensile strength, elongation and flexibility to the final product. Molding resins can achieve higher elongations and “toughness” without sacrificing modulus. Moreover, unlike other flexibilizing glycols, MPO will not lead to losses in chemical resistance, water resistance or weatherability. Isocyanate modified unsaturated polyester resin molding system benefit from incorporating MPO into the polyester. The two primary hydroxys of MPO ensure reliable, rapid isocyanate chain extension in these hybrid resin system.

Unsatured Polyester Resins (Gel Coats). 

    With their exacting performance requirements, gel coats gain key benefits from the inherent properties of MPO. Gel coats formulated with MPO-based polyesters have high strength and elongation characteristics, excellent blister resistance and excellent weatherability. Comprehensive testing has demonstrated that MPO enhances the toughness of gel coats without sacrificing extended weatherability performance. MPO-based polyester used in these applications are suitable for use in marine and fiberglass panel resins.

Saturated Polyester for Coating.
   
MPO unique capability to flexibilize high aromatic content-phthalic, isophthalic, or terephthalic-based polyesters enables O-T flexibility coupled with H-2H pencil hardness. This coupling of hardness and flexibility is only possible because the MPO-based polyesters have a very low tendence to form crystalline, insoluble polyesters- even when high aromatic content is utilized. Extensive testing of MPO base polyesters also has demonstrated that MPO can be utilized to make highly weatherable polyester binders that can compete effectively with top-of-the-line exterior durable polyesters.

Polyurethane. 
     MPO is a building block that can be broadly utilized in the diverse field of polyurethane coating, adhesives, sealants and elastomers. Application systems include: 2K industrial maintenance coatings, aqueous polyurethane dispersions, liquid prepolymers for urethane elastomers and urethane adhesives. As a liquid diol, MPO can be used as a chain extender to build molecular weight and performance in urethane elastomers, adhesives and sealants. The branched structure of MPO leads itself especially well to the manufacturing of clear, pliable sealants and adhesives. In addition, MPO has excellent compatibility with conventional polyols and dependable reactivity with the isocyanate component. MPO is an ideal intermediate for polyester polyols because it yields all primary hydroxyl-containing polyesters. Its unique structure makes it possible to produce liquid polyesters that are readily dissolved in conventional coatings solvents. MPO based polyester polyols also demonstrate excellent compatibility in urethane adhesive formulations.

Plasticizers. 

    The unique noncrystallizing nature of MPO-based diesters and polyesters can be a significant handling advantage for the thermoplastics (PVC) compounder. The very low glass transition temperatures of MPO-based ester and polyester derivatives ensure efficient utilization of these premium polyesters. End uses for MPO-based plasticizers include: PVC Laminating Films Refrigerator Gaskets Vinyl Electrical Insulation (wire, cable, tape, etc.)

MPO Alkoxylate.

    MPO reacts with ethylene oxide or propylene oxide to from MPO alkoxylate. The main applications are the manufacture of UV curing agent monomer, polyester polyol, painting, ink, adhesive and polyurethane.

 

MPO Diacrylate/ Dimethacrylate and MPO Alkoxylate Diacrylate/ Dimethacrylate.

    MPO or MPO alkoxylate reacts with acrylic acid/ methacrylic acid to from MPO diacrylate/ dimethacrylate or alkoxylate diacrylate/ dimethacrylate. Both glycol diacrylate can be used in quite broad applications as starting materials and intermediates for thermosetting paints, adhesives, nonwoven fabric binders, photosensitive agents, paper finishing agents, copolymer modifiers and cross-linking agents. But MPO alkoxylate diacrylate/ dimethacrylate has lower skin irritation and odor than MPO diacrylate/ dimethacrylate.

MPO Polycarbonate. 

    MPO reacts with DMC or DEC to form MPO polycarbonate. Recause MPO is a branched aliphatic diol with two primary hydroxyls that inhibits the crystallization of MPO polycarbonate allowing it to remain liquid even in cold temperature. The main applications are the adhesives softsegment intermediates for polyurethanes, coating and ink.

Modified Polyethylene Terephthalate (PET) 

    MPO provides an effective crystallization modifier for PET. The branched structure of MPO helps control both thermal and crystallization properties of the final polyester products. This control offers differential performance features in polyester bottle and fiber resin applications. PET is essentially a highly crystalline resin and, therefor, appear opaque. It is known to use a small quantity of isophthalic acid together with terephthalic acid as the dicarboxylic acid component of PET or to use MPO together with ethylene glycol as the glycol component of PET can obtain transparent bottle. But isophthalic acid is very expensive, MPO modified PET can reduce PET bottle cost. MPO has a side chain of a methyl group which renders the polyester an asymmetric chemical structure, if this compound is used as PET Fiber, the result PET fiber will be made in irregular form, and dyestuff molecules will attach to it readily. Therefore, the resulting PET fiber are endowed with excellent dyeability, lesser elongation and greater strength.

Personal Care. 
    MPO also can be used in an amollient, emulsifier and humectant. The hydrophilic/ lipophilic balance of MPO provides solvency to both polar and non-polar active components. This feature ensures shelf-stable formulations and clear, homogenous solution.

Storage and Handling
    MPO is a stable material. It should be stored away from strong mineral acids. If low water content is important, it should not suffer excessive exposure to atmospheric moisture and should be stored under a nitrogen blanket. It can be both shipped and stored in phenolic-lined, mild steel containers. Stainless steel will also help extend product consistency.
