We can produce 8,000T/Year of Isobutylene by MTBE cracking method. This equipment can produce chemical grade Isobutylene and polymerization grade Isobutylene. The assay can reach 99.9%. We are the one of largest manufacturer in China for Isobutylene.

Our company is located in the LinAn City industry zone, which is an economic development zone of Zhejiang province. Our company covers an area of 33300sq.m. with 100 employees.

Our operation is following the regulations of ISO9001 quality system and ISO14001 environment system.


Polyisobutylene is a synthetic rubber, or elastomer. It is special because it is that only rubber that is gas impermeable, that is, it is the only rubber which can hold air for long periods of time. You may have noticed that balloons will go flat after a few days. This is because they are made of polyisoprene, which is not gas impermeable. Because polyisobutylene will hold air, it is used to make things like the inner liner of tires, and the inner liners of basketballs.

Polyisobutylene, sometimes called butyl rubber, and other times PIB, is a vinyl polymer, and is very similar to polyethylene and polypropylene in structure, except that every other carbon is substituted with two methyl groups. It is made from the monomer isobutylene, by cationic vinyl polymerization.
