Halogenated butyl rubber stoppers (hereinafter referred to as rubber stoppers) are divided into 4 categories according to cleanliness: rubber stoppers that need to be washed, rubber stoppers that need to be rinsed, rubber stoppers that need to be sterilized, and rubber stoppers that are ready to use The common point is that the production processes […]

As the vulcanization of rubber balls tends to be “high temperature and short time”, many new processes tend to adopt continuous and streamlined production modes, and the necessity of anti-reversion is becoming more and more obvious. Effective anti-return measures have been adopted. Was put on the agenda. In this regard, foreign countries take a step […]

Emulsion polymerization is a polymerization method widely used in copolymer rubbers (including latex polybutylene, butyronitrile, chloroprene, etc.) containing butadiene or a derivative thereof (e.g., chloroprene). The early emulsion polymerization into rubber uses a higher polymerization temperature (40~50 °C), and the obtained synthetic rubber is commonly called “hot butyl benzene”. The disadvantage is that the molecular […]

Solution polymerization generally refers to a reaction process in which a monomer is dissolved in a solvent and an initiator is added to carry out polymerization. The advantages of the method include easy heat dissipation, easy control of the reaction process, low viscosity of the solution, easy purification, and easy molecular weight adjustment. The disadvantage […]
