Flame Retardant PP Compound | UL94 V-0 Polypropylene
Flame retardant polypropylene compound with UL94 V-0 rating. Halogen-free options. For automotive, electrical, and industrial applications.
Problem & Solution
The Problem
Polypropylene components fail fire safety tests. Electrical housings, automotive under-hood parts, and industrial enclosures require UL94 V-0 or V-2 ratings. Non-compliant materials pose liability risks and market access barriers in automotive (FMVSS 302) and electrical (IEC 60695) sectors.
Our Solution
Our flame retardant PP compound achieves UL94 V-0 at 1.5mm thickness with 15-20% loading. Halogen-free grades available for RoHS/REACH compliance. Maintains mechanical properties (tensile 25-35 MPa, impact 4-8 kJ/mΒ²) while providing LOI 28-32% oxygen index.
Technical Specifications
Key Advantages
UL94 V-0, V-1, V-2 ratings at 1.5-3.0mm
Halogen-free options (Br-free, Cl-free)
LOI 28-32% oxygen index
Tensile strength 25-35 MPa retained
Notched impact 4-8 kJ/mΒ²
Processing temp 190-230Β°C
Applications
Technical Advantages
Synergist optimization: Phosphorus-based FR + nitrogen synergist achieves V-0 at lower loading (15%) vs. traditional antimony systems (25%), reducing cost and maintaining impact strength.
Thermal stability: Proprietary stabilizer package prevents FR degradation during processing, allowing regrind use up to 20% without flame rating loss.
Color compatibility: FR system does not interfere with pigments, enabling full color range including white and light shades with ΞE<1.0 color consistency.
Automotive compliance: FMVSS 302 horizontal burn test passed at <100mm/min burn rate. Suitable for interior trim, under-hood, and battery compartment applications.
