Non-Halogen Intumescent MB for Fire Safe PPRC Pressure Pipes

Engineered for EN13501

Non Halogen intumescent masterbatch for Fire Safe PPRC Pressure Pipes

Engineered for EN 13501

A high performance non-halogen intumescent
masterbatch designed for PPRC pressure pipes and
multilayer systems requiring EN 13501-1 B s1 d0.

It delivers low smoke, strong char, and anti drip behaviour while maintaining weldability and mechanical strength.

Why Non Halogen?

Halogenated FR systems struggle with smoke, corrosive gases, and poor char – making B-s1-d0 difficult to achieve.

They can also affect weldability and long term pipe performance.

Our new non-halogen masterbarch offers a cleaner, safer, future-proof alternative.

• No halogens, no red phosphorus
• Low smoke, no corrosive gases
• Excellent char formation for B class performance
• Stable weldability and pressure resistance
• Compliant with modern building and environmental expectations

Performance Summary

• Supports EN 13501-1 B-s1-d0
• Strong char formation
• Low smoke
• Anti drip behaviour
• Maintains weldability and mechanical integrity
