Application Areas

Tires, rubber compounds, seals, hoses, new energy fields, coatings, printing, textile rollers, etc.

Product Characteristics

1. Low migration, low exudation, increasing rubber compound stability. Reduces Mooney density in rubber compounds, improving processing performance. Increases crosslinking density in rubber products, enhancing product hardness, and improving wear resistance and low-temperature resistance.

2. Low molecular weight, good flowability at room temperature, easy to disperse;

3. Molecular chains consist only of hydrocarbon structures, low dielectric constant, low water absorption;

4. Can be thermally and photocrosslinked, with crosslinked properties comparable to ordinary vulcanized rubber; easy to process, significantly reducing processing energy consumption;

5. Can be processed in a liquid state, requiring no solvents, no pollution; participates in co-vulcanization, allowing adjustment of physical properties and vulcanization speed.
