Product Detail

Product Tags

Description:Stearyl methacrylate is an important chemical raw material, its homopolymer or copolymer of maleic anhydride and styrene, may improve the fluidity of petroleum products at low temperature. Stearyl acrylate polymers have a comb structure, which solution has many characteristic. It is widely used as a reactive diluent and crosslinker in the radiation curable system. Also be used as plastics, rubber modifiers, coating leveling agents, coatings and paints release agents, oil pour point depressants, various binders.

 

Application:

1. Used in crude pour point depressant, fabric finishing agent, leather auxiliary, plasticizer, oil absorbing resin.

2. It can be used to make coatings, adhesives, paper coating resins, lubricating oil additives, especially suitable for textile pulp synthesis, to help pulp film formation, improve pulp toughness, and increase surface smoothness

 

Package:170kg net weight or requirement as Customer.
