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.
