Formulators of coatings, adhesives, sealants, and elastomers (CASE), as well as producers of foams and applications for elastic fiber, utilize a wide variety of polyols in order to fulfill the requirements for product performance. This is done to ensure satisfactory results of their products. This c Read More

The basic refining methods for polyether polyols can be broadly classified as follows: (1) Neutralization using inorganic or organic acids. In the polymerization reaction for the production of polyether polyol, inorganic acids are rarely used as neutralizing agents for systems using alkali metal hyd Read More

Thermoplastic polyurethane (TPU) is a linear block polymer consisting of soft chain segments (long-chain oligomeric diols) and hard chain segments (diisocyanates and chain expanders). Due to the strong polarity of the hard chain segments, the microphase regions of the hard chain segments are formed Read More

Trimethylolpropane, TMP, cas 77-99-6, is a white crystal or powder with three typical hydroxymethyl groups on its molecule, and thus has polyol properties similar to glycerol, which can react with organic acids to form mono- or multi-esters, with aldehydes and ketones to form acetals and ketones, an Read More

PTMEG, also called Polytetramethylene Ether Glycol, Polytetrahydrofuran, cas 25190-06-1, is an important chemical raw material, mainly used in the preparation of spandex in the field of chemical fiber, and in the preparation of elastomer, adhesive, coating, sealant and other fields in the non-fiber Read More

HDO is short for 1,6-hexanediol,HEXAMETHYLENE GLYCOL, cas 629-11-8, which is an important polyurethane raw material widely used in the polyurethane industry as a major component of elastomers and rigid foams. The following are the applications of HDO in the polyurethane industry. Preparation of poly Read More

PTMEG is also called Polytetramethylene Ether Glycol or Polytetrahydrofuran.At room temperature, low molecular weight PTMEG is colorless liquid, while higher molecular weight PTMEG is white waxy, easily soluble in alcohols, esters, ketones, aromatic hydrocarbons and chlorinated hydrocarbons, insolub Read More
