Methylene Diphenyl Diisocyanate (MDI) - Essential Building Blocks for Polyurethanes

Methylene diphenyl diisocyanates (MDIs) are essential building blocks in the production of polyurethanes, urethane-prepolymers, and polyisocyanurate polymers in many industries.  Because of their reactivity and versatility of combining with an wide array of curatives and chain extenders, MDIs are used in countless diverse applications. End-uses for these quite versatile diisocyanates include foam products, cast elastomers, thermoplastic polyurethanes (TPUs), fibers, and CASE (coatings, adhesives, sealants & elastomers) products.   MDIs are the most-produced diisocyanate on a global basis.

Gantrade P-1000 and P-2000 PTMEG based Diamines

Gantrade’s P-1000 and P-2000 are oligomeric diamine curatives based on the p-aminobenzoate ester of PTMEG 1000 and PTMEG 2000, respectively. The Gantrade P-1000 is similar to Versaink® P-1000. The P-2000 is a new material, developed for applications where a lower Durometer is required. A diamine based on the p-aminobenzoate of PTMEG 650 is also available from Gantrade Corporation.

Dynamic Performance of Polyurethanes Based on Polycaprolactone Polyols

Polycaprolactone polyols are a special class of polyester polyols preferred in polyurethane elastomer applications where high dynamic durability, broad temperature profiles, very good hydrolysis resistance, and exceptional elastomeric properties are required.  Polyester polyols, as a class, are generally selected for urethane applications where high tensile strength and tear resistance, sliding abrasion resistance, flex fatigue resistance, oil, grease and solvent resistance, and high temperature and oxidative stability are needed.

Polymer Applications of Allyl Alcohol

Allyl alcohol (AAL) is a readily available, water-soluble liquid used as a comonomer and a chemical intermediate. As a dual-functional monomeric building block, AAL consists of a polymerizable allylic moiety and a reactive hydroxyl moiety. For the purpose of this discussion, we will show the versatility of allyl alcohol as a functional monomer.

Q&A With the Experts: 2-Methyl-1,3-Propanediol (MPO)

Gantrade offers the incredibly versatile diol, 2-Methyl-1, 3-Propanediol (MPO) for a range of market applications for unsaturated polyester resins, including composites and gelcoats, as well as saturated polyester for liquid can & coil coatings, powder coatings, polyester polyols for polyurethanes, and more.

We sat down with John Drummond of Gantrade Europe and Helen Wu with the company’s US group for a Q+A session sparked by increased interest worldwide in the use of MPO.

Applications of N-Butyl Acrylate

N-butyl acrylate (BA) is the largest-volume acrylate ester used in the production of all-acrylic, vinyl acrylic and styrene acrylic copolymers.  BA offers price-value and accounts for about 60 percent of the global acrylic ester monomer demand, with a consumption volume of over 2,000 kilo tons.  

The other major acrylate esters include methyl acrylate (MA), ethyl acrylate (EA), and 2-ethylhexyl acrylate (2-EHA).  Butyl acrylate is used as a “soft-monomer” to improve low temperature properties and toughness. The major markets for BA are in paint & coatings, such as architectural and automotive coatings, followed by adhesives and sealants market.  Other application areas include inks, textile, paper and leather finishes, and caulks.

Another significant and growing segment for BA is in thermoplastic ethylene acrylate copolymers (EAC), at BA levels up to 35 % in copolymers.  EBA copolymers are used as a impact modifier and processing aid in thermoplastics improving properties such as toughness, flexibility, molding characteristics and part appearances.  End use applications include packaging, multilayer films and adhesives.

N-Butyl Methacrylate: a Plasticizing Methacrylate Monomer

N-butyl methacrylate (n-BMA) is a versatile, plasticizing methacrylate monomer used in the production of homopolymers, copolymers and products that we see and use in everyday life.

As a homopolymer, we see poly (n-BMA) used in adhesives and as a polymeric plasticizer for harder resins.  Copolymer applications include water-borne industrial and architectural paints, textiles, paper & leather coatings, wood coatings, adhesives, inks, caulks, and sealants.  N-BMA also demonstrates flexibility, durability, UV, and moisture resistance in exterior decorative paints and automotive finishes.

In solvent based systems, it improves solubility of the copolymer resin.  Copolymers with methyl methacrylate (MMA), exhibit enhanced flexibility and toughness without the need for a plasticizer.
