1.Key application areas Rubber Industry: Tyre vulcanisation: Sulphur + accelerator (CBS 1.2phr + S₈ 2.5phr) Crosslink density: 4×10-⁴ mol/cm³ 30% reduction in dynamic heat generation Sealing products: Peroxide vulcanised EPDM (DCP 1.5%) Compression permanent deformation <20% (150℃×70h) Plastic modification: Cross-linked polyethylene (XLPE): Silane grafting method (VTMS 2% + catalyst) Temperature resistance grade from 70°C → 90°C Breakdown strength >30kV/mm Polypropylene foaming: Radiation crosslinking (electron beam 50kGy) Bubble density＞10⁶ cells/cm³ Biomaterials: Hydrogel: Photoinitiated crosslinking (Irgacure 2959 0.1%) Dissolution rate >500 per cent Cytocompatibility >95% Medical catheters: Peroxide cross-linked silicone rubber Tear strength >30kN/m 2 Typical problem solutions Uneven crosslinking: Cause: Poor dispersion or temperature gradient Countermeasure: Use twin-screw extruder (shear rate > 500s-¹) Temperature rise in stages (e.g. 120°C → 160°C step vulcanisation) Side reaction control: Peroxide system pre-crosslinking: Addition of TAIC (Triallyl Isocyanurate) 1 per cent. Coking time extended to >10min (160°C) Insufficient cross-linking: Silane cross-linked polyethylene: Increase hydrolysis temperature to 90°C Add dibutyltin dilaurate (0.1%)
