Polyurethane foam will be fully developed
[Jiuzhi Plastics News] Nowadays, with the maturity of foam production, the market supply range has also expanded. Although the polyester flexible foam has strong insulation performance and good performance, its cost is higher and the price is higher. Expensive, not suitable for certain commodities, thus urging the need to find a resin that is lower in price than polyester to replace it.
After various studies, DuPont first used polytetramethylene ether glycol instead of polyester to make flexible foam. This foam is soft, excellent in hydrolysis resistance, good in resilience, and its price. Just close to the price of polyester.
Later, a polyether resin prepared by using inexpensive olefin oxide, castor oil or the like as a raw material was used for the production of a flexible polyurethane foam. The products made from this polyether have relatively low prices and relatively good performance, which has brought about another major change in the polyurethane industry.
With the continuous research work in various countries, new varieties and new processes are continuously developed, and new equipment is constantly being created, which has led to the comprehensive development of polyurethane foam. It can be said that polyurethane foam is a foam developed from a polyester type and developed from a polyether type.
