Polytetramethylene ether glycol (PTMEG/PTG) is produced by the acid catalyzed polymerization of tetrahydrofuran (THF). It is a straight-chain diol with repeated tetramethylene ether units.
2-Methyl-1,3-propanediol is a product produced through hydroformylation of allyl alcohol with carbon monoxide and hydrogen, which is then followed by hydrogenation. It is a colorless low viscosity liquid with low toxicity. It is a non-linear diol with a unique methyl branch.
After spray drying, VAE emulsion is turned into a white powder which is a copolymer of ethyl and vinyl acetate. It is free-flowing and is easy to emulsify. When dispersed in water, it forms a stable emulsion. Possessing the ......More→
Polyvinyl alcohol (PVA), a white/yellowish granule or powder, is a stable, non-toxic, and water-soluble polymer. PVA possesses good film-forming property, and the film formed from it has excellent adhesion, solvent-resistance, abrasion-resistance, high tensile strength, and great oxygen barrier property. ......More→
