Polyether is a type of polymer composed of C—O—C bonds. It mainly uses bimetallic catalysts or strong bases as catalysts to embed ethylene oxide (EO), ring on active O—H or N—H bonds. It is formed by propylene oxide (PO) or butylene oxide (BO). Polyethers are mainly used as defoamers to take advant... read more
The rapid development of the concrete industry has placed higher requirements on the admixtures used in concrete, especially the performance of water reducing agents. Polycarboxylic acid high-performance water reducer is the latest generation of water reducer. Its high water reduction, good dispers... read more
The composite material based on resin and rubber contains a large amount of organic compounds and has certain flammability. Flame retardants are additives that can prevent the ignition of polymer materials or inhibit flame propagation. The most commonly used and most important flame retardants are ... read more
Resorcinol formaldehyde Resorcinol-formaldehyde resin glue is very strong and durable (resistant to immersion in boiling water, weak acid, salt water, solvent, mold, fungus, ultraviolet light, etc.). It must be mixed before use (liquid resin and powdered catalyst). It has a deep purple color and ma... read more
animal glue For many centuries, animal glue, especially raw hide glue, has been the main adhesive of choice for many types of woodworking (including furniture and shoe factories). It is made of collagen extracted from animal skin (hidden). Its chemical properties are similar to edible gelatin, and ... read more
