-
- BPDH is highly effective as a cross-linking agent for polyethylene, including both LDPE and HDPE, as well as ethylene-vinyl acetate copolymers. Cross-linking occurs at temperatures above 170°C, while no cross-linking happens below 140°C. It is typically used at concentrations between 0.5% and 3% by weight, although for more resistant materials, the dosage can be increased up to 5%.
-
Inquiry - tert-Butyl cumyl peroxide (TBCP)
CAS 3457-61-2
- Molecular Formula: C₁₃H₂₀O₂
- Molecular Weight: 208.3
- UN No.: 3105
-
- This compound is often used in rubber manufacturing as a vulcanizing agent, ensuring reliable and consistent results. It’s valued for its strong scorch resistance, with a safe working temperature around 135°C, while vulcanization typically occurs at 175°C. Its ability to enhance rubber properties makes it ideal for high-demand applications.
