While Lycra, spandex, and elastane are all the same material, regional variants of the term "elastane" are most commonly used to refer to this type of fabric in continental Europe. This textile is composed of a long chain polymer known as polyurethane, and it is known in technical ...
PURPOSE:To obtain the title polymer having a specific logarithmic viscosity, useful as an elastic yarn having excellent chlorine resistance, water resistance, elastic recovery, heat resistance, by polymerizing a polymer diol having specific structural units and a number-average molecular weight, polymer...
After the reaction with the epoxide, the polymer is preferably neutralized, e.g. with HCl. It is possible to react all three components simultaneously, but conditions must be such that chains of anhydride-epoxide products are not predominantly formed. In making polyurethane foams, polymers of ...

Polymer polyol VPOP-45 Introduction The VPOP-45 Mainly used for high load-bearing polyurethane,high-resilience block flexible foam,molding flexible foam,integral skin flexible foam and semi-flexible foam etc. Specification Test project Unit Indication range Appea...
Why is polyurethane the most popular option? Because it has a lot of the same functionalities as the products above, but it is considered environmentally friendly, too, as it is non-toxic. Polyurethane is apolymer formed by the reaction of isocyanates and polyols. This reaction gives i...
” Our customers include many Fortune 500 companies, most of whom have been customers for 20+ years. Their drive to become industry leaders has helped us do the same. A variety of additives can be incorporated into polyurethane to enhance wear properties, add lubricity, or produce parts that...
aThe current collector for lithium-polymer batteries is typically made of either copper or aluminum foil surrounded by a low thermal conductivity material such as polyurethane. The battery case is made of polypropylene, reinforced polypropylene, or polystyrene. 受电器为锂聚合物电池低导热性材料或铝芯...
摘要: PROBLEM TO BE SOLVED: To obtain a propylene-based polymer or polymer composition for biaxially oriented blow molding having good impact resistance and transparency and excellent in uniform stretchability and provide a biaxially oriented blow molded vessel....
