PVC Compound for Cable Insulation Suppliers
Source cable-grade PVC compounds for wire insulation and cable sheathing from verified B2B suppliers on Towobo. PVC remains the dominant insulation material for power cables, data cables, flexible wiring, and building wire worldwide — and the compound formulation determines the electrical performance, temperature rating, flexibility, and regulatory compliance of the finished cable. This guide covers compound grades, Shore hardness, temperature classes, RoHS requirements, and how to evaluate cable-grade PVC compound suppliers.

PVC cable compounds are formulated from PVC resin, plasticisers, heat stabilisers, fillers, and processing aids. The compound formulation determines the key performance properties. Temperature rating: standard cable-grade PVC insulation is rated to 70°C (or 75°C, designated T2 under IEC 60227). Heat-resistant grades are rated to 90°C (HR or T3); special grades up to 105°C. Higher temperature ratings require more thermally stable plasticisers and heat stabilisers. Flexibility and Shore hardness: building wire insulation typically uses a hard compound with Shore D hardness of 70–85. Flexible cord (appliance leads, extension cables) requires a soft compound with Shore A hardness of 55–75. Flexible grades require higher plasticiser loading. Plasticiser type: DINP (diisononyl phthalate) and DIDP (diisodecyl phthalate) are the standard non-restricted plasticisers for cable applications. DEHP, DBP, BBP, and DIBP are restricted under EU REACH and RoHS for cables destined for the EU market — always confirm the plasticiser system with the compound supplier. Lead stabilisers: historically common in cable PVC but banned in EU cables under RoHS Directive 2011/65/EU since 2013. Confirm the compound uses a calcium-zinc (Ca-Zn) or organic tin stabiliser system for EU-market cables.
