Description

technical field [0001] The invention relates to a high-performance and easy-to-process MPR hot-melt rubber material, which belongs to the technical field of synthesis and processing of hot-melt rubber materials. Background technique [0002] Early rubber was latex taken from plants such as rubber trees and rubber grasses, which were processed into materials with elasticity, insulation, impermeability to water and air. High elastic polymer compound. Divided into two kinds of natural rubber and synthetic rubber. Natural rubber is processed by extracting gum from rubber trees, rubber grass and other plants; synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in all aspects of industry or life. At present, the MPR hot-melt rubber materials used in China are all produced by American company Advanced Polymer Alloys®. Its excellent mechanical and physical properties are widely used in automobile door and window sealing strips; Dif...
