The production capacity of C4 plant in China is about 2.8 million tons/year

but there is almost no domestic commercial product polybutylene resin in China. Polybutylene resin

used as pipe fitting material

is completely dependent on imports. Only Basell of the Netherlands

Mitsui Petrochemical of Japan and other companies abroad can carry out industrial production of polybutylene. For the reason of technical protection

Chinese enterprises wishing to produce polybutylene pipelines should apply to foreign companies. After investigation

they believe that only when the production conditions are qualified

can they be included in the supply list and limited supply be carried out. Therefore

the price of polybutylene has always been at a high level. At the same time

due to a series of production problems such as slow reaction

less heat release

high viscosity

and easy caking in butylene polymerization

domestic industrialization is difficult. In 2017

with the joint efforts of the technical team of Chambroad Petrochemical Co.

Ltd. (hereinafter referred to as “Chambroad Petrochemical”)

polybutylene alloy

a special material for pipes

was successfully produced. Practical transformation of equipment

accurate control of process indicators

lean management of processes and other measures were taken to make the prouduct meet the all standards of testing

analysis and downstream trial.
