Rubber Blocks

Isoprene rubber is a high-performance rubber used in tire production. It is widely used in the tire manufacturing industry for its stable chemical properties.

It has good elasticity, cold resistance (glass transition temperature -68°C) and high tensile strength.

Its resistance to cut and tear under oxidation resistance and multiple deformation conditions is higher than that of natural rubber,

but its processing properties such as mixing and calendering are slightly worse than those of natural rubber.

In tire production, the application of isoprene rubber in different parts can improve tire processing performance or enhance tire quality. Load-carrying radial tires: 30 parts of isoprene rubber are used to partially replace natural rubber in parts such as crown rubber, sidewall rubber, and transition layer rubber; Passenger car radial tires: It is used in filling rubber, carcass rubber, and cap layer rubber, and 100% of the high-hardness filling rubber is isoprene rubber; Because isoprene rubber and natural rubber have the same main chain molecular structure, their physical parameters are basically the same, and isoprene rubber has a light-colored appearance, uniform quality, and high purity, it is also widely used in rubber products such as shoes, rubber tubes, tapes, car bodies, and shock absorbers. Isoprene rubber has high cleanliness and is also used in rubber products that are in direct contact with drugs or food.

Isoprene rubber properties

Isoprene rubber is a synthetic rubber obtained by polymerization of isoprene monomer under the action of a catalyst. Its microstructure is similar to that of natural rubber, so it is also called synthetic natural rubber. It is a general synthetic rubber with good comprehensive performance. According to the different catalytic systems, it can be divided into lithium isoprene rubber, titanium isoprene rubber and rare earth isoprene rubber. Isoprene rubber has similar chemical composition, stereostructure and mechanical properties to natural rubber; it has good original strength, basic viscosity, aging performance and rebound performance. All rubber products using natural rubber can be replaced by isoprene rubber. At present, isoprene rubber is mainly used in the tire industry, and is also widely used in hoses, tapes, medical treatment, shoemaking and other industries.
