▎Products Description
30+ Years PVC Modification Technology · ISO Certified Manufacturer
Export to 120+ Countries Worldwide · SGS, Intertek, Bureau Veritas Verified
SmallBoss Flame Retardant PVC Compound is engineered for high-fire-safety applications including building materials, electrical conduits, and cable insulation. With a Limiting Oxygen Index (LOI) of 32% or above, our compound achieves UL 94 V-0 rating and meets IEC 60332-3 flame propagation requirements, making it ideal for mandatory fire-safety applications in public buildings and high-voltage cable systems.
Available in both rigid and flexible grades from Shore A 70 to Shore D 85, our compound supports extrusion and injection molding processes. It delivers excellent thermal stability, low smoke emission, and compliance with RoHS and REACH regulations for global market access.
| Parameter | Value |
|---|---|
| Appearance | Grey / Black granules |
| Specific Gravity | 1.48 ± 0.03 g/cm3 |
| Hardness | 85 ± 3 Shore A |
| Tensile Strength (min.) | ≥ 12.5 MPa |
| Elongation at Break (min.) | ≥ 150 % |
| Limiting Oxygen Index (LOI) | ≥ 32 % |
| Flammability Rating | V-0 |
| Flame Propagation | Pass |
| HCl Emission (max.) | ≤ 18 % |
| Smoke Density (max.) | ≤ 300 |
| Thermal Stability @ 200°C | ≥ 50 min |
| Low-Temperature Brittleness | ≤ -20 °C |
| Heat Aging @ 100°C/168h | ≤ ±25 (retention) % |
| Volume Resistivity (min.) | ≥ 1×1013 Ω·cm |
| Regulatory Compliance | RoHS, REACH, UL |
| Processing Method | Extrusion / Injection Molding |
Our compound achieves LOI ≥ 32% and UL 94 V-0 rating, ensuring reliable fire performance that meets building codes and cable safety standards across global markets.
Low-smoke formulation reduces smoke density below 300 and limits HCl emission to under 18%, improving evacuation safety in public buildings and enclosed spaces.
Enhanced thermal stability at 200°C for 50+ minutes ensures smooth processing without discoloration or degradation, reducing scrap rates and production downtime.
Balanced formulation maintains tensile strength above 12.5 MPa and elongation above 150% while achieving superior flame retardancy, avoiding the brittleness common in high-filler compounds.
Every batch undergoes rigorous QC testing including mechanical properties, dimensional stability, and color consistency. Our ISO-certified lab ensures compound performance matches specifications batch after batch.
Rigid PVC compound for electrical conduit pipes and fittings requiring flame retardancy and mechanical strength in commercial and residential construction.
Flexible PVC compound for cable insulation and sheathing in power cables, control cables, and building wires meeting IEC and UL fire standards.
Fire-retardant PVC profiles and panels for wall cladding, cable trunking, and ceiling systems in hospitals, schools, and transit stations.
Specialized compound for rail, automotive, and marine cable applications requiring EN 45545-2 and NF F 16-101 fire safety compliance.
Custom extruded profiles for specialized applications in industrial and commercial settings.
Tailored compounds developed to meet specific customer requirements for hardness, color, and processing characteristics.
