GP-204 (N,N’-1,3-Phenylene bismaleimide) is used to prevent reversion and improve the heat resistance, anti-aging properties and adhesion of the rubber and tire cord and vulcanized rubber modulus.  (1,1’-(1,3-phenylene)bis-1H-pyrrole-2,5-dione) is a non-sulfur vulcanizing agent and primarily used in EPDM and chlorosulfonated polyethylene applications.

GP-204, Oiled (N,N′-(1,3-Phenylene)dimaleimide) PDM is a versatile chemical used in rubber vulcanization and as an adhesive additive. When added to rubber compounds, BMI reacts with the rubber chains to form cross-links.  These links improve the mechanical properties of the rubber, such as its strength, durability, and heat resistance. Additionally, when combined with sulfur, BMI prevents reversion, which improves the heat resistance and reduces heat and anti-aging of the rubber. It also improves the adhesion of the rubber and tire cord and vulcanized rubber modulus. PDM, another non-sulfur vulcanizing agent, solves copper wire and copper electrical contacts' pollution problems. Typically caused by sulfur vulcanizing agents' black copper sulfide generation.

Commonly used cross-linking agent for rubber vulcanization.

When added to rubber compounds, BMI reacts with the rubber chains to form cross-links, which improves the mechanical properties of the rubber, such as its strength, durability, and heat resistance. BMI is also an adhesive additive in rubber compounds, improving the adhesion between rubber and other materials, such as metal or plastic.

PDM is a non-sulfur vulcanizing agents that solve copper wire and copper electrical contacts because of sulfur vulcanizing agent to generate black copper sulfide pollution problems.
