Bio-based itaconic ester rubber is a new type of rubber material obtained from the copolymerization of itaconic ester and butadiene. Sourced from renewable bio-based materials, compared with traditional petroleum-based synthetic rubber, the production of 1 ton of bio-based itaconic ester rubber can reduce CO2 emissions by about 1.4 tons.
1. Bio-based component content of 20%-80%.
2. The product structure and performance can be flexibly adjusted to meet the use requirements of different application scenarios.
Automotive: Tires, seals, interiors, shock absorption, hoses, etc.
Consumer products: Shoe materials, medical gloves, etc.
