Polymer Crosslinking Solutions
High-performance organic peroxides and azo initiators engineered for efficient polymer crosslinking. Serving the wire & cable, pipe, foam, and rubber industries worldwide.
Driving performance through controlled crosslinking
Polymer crosslinking is a critical process that transforms thermoplastic materials into thermoset networks, delivering superior mechanical strength, thermal stability, and chemical resistance. As a trusted supplier of organic peroxides and azo initiators, Shandong Do Sender Chemicals provides reliable, cost-effective crosslinking solutions for polymer manufacturers and compounders globally.
Our products are widely applied in wire and cable insulation, PE pipe production, EVA/EPDM rubber foaming, and specialty elastomer curing. With decades of manufacturing expertise and rigorous quality control, we ensure batch-to-batch consistency that meets the demanding requirements of industrial-scale polymer processing.

Selecting the right crosslinking agent depends on processing temperature, polymer type, and desired cure characteristics. Our portfolio covers the full spectrum of peroxide- and azo-based crosslinking technologies.
Organic Peroxide Crosslinking
Dialkyl peroxides, peroxyketals, and peresters provide a wide range of decomposition temperatures for conventional and high-temperature crosslinking applications.
- Dicumyl Peroxide (DCP) — Industry standard for XLPE, EPDM, and general crosslinking
- Di(tert-butylperoxyisopropyl)benzene (BIPB) — Low-odor alternative for wire & cable
- 2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane (DHBP) — For silicone rubber and EVA foaming
Azo Initiator Crosslinking
Azo compounds generate free radicals through thermal decomposition, offering precise, predictable kinetics for controlled crosslinking and modification of polymers.
- Azobisisobutyronitrile (AIBN) — Low-temperature initiator for acrylics and styrenics
- Azodicarbonamide (ADC) — Chemical blowing agent for foamed plastics and rubber
- AMBN / ACVA series — Water-soluble azo initiators for emulsion polymerization
