Ding Ji rubber is a copolymer of isobutylene and a small amount of rubber matrix. Because of its structural features, its gas permeability is the lowest in the hydrocarbon rubber, butyl rubber at 40 ℃, gas permeability coefficient of about 1/120 for natural rubber, styrene butadiene rubber 1/8. Ding Ji rubber has good weather resistant performance. Ozone resistance, ozone, and the crack growth rate slow. Similar to the EPDM material, which has excellent resistance to chemicals and polar flux, good insulation and ozone resistance. Special Ding Ji rubber is its very low gas permeability and high shock absorption ability. Ding Ji rubber self-adhesive and mutual viscosity is poor, and poor compatibility with other rubber. Compared with other rubber, vulcanized slow.

(three) colour:

Black color, can also be specified by the client.

(four) application:

Ding Ji rubber with low permeability, application and automobile tire inner tube, inner liner tubeless tires, white wall, manufacturing car tire inner tube of bicycle; Ding Ji rubber heat resistant performance is good, can be used to make water births, sulfurized capsules. Also can be used for the production of medical bottle stopper, disposable syringe plunger.
