Paxymer – The Green FR

Paxymer is the flame retardant system for polyolefin plastics. It is 100% halogen free and our solutions are delivered as a synergist and as a master batch for all polyolefins e.g. PP, PE, EVA, TPE, TPO. Paxymer is compatible with mineral and intumescent (P/N-systems). We can also formulate our functional polymers to meet your specific demands.

Paxymer is designed to provide a fully functional substitution for halogenated solutions:

Paxymer ensures safe burning behavior.
Paxymer retains base material mechanical and processing functionality.
Paxymer meets current and future chemical and environmental legislation.

Designed to Burn Safely

Paxymer is designed for safe burning behavior. Our new, patented, flame retardant mechanism results in a unique burning process that saves lives in a fire situation.

Paxymer is designed with functional polymers to address the three main problems encountered in burning polymers; heat release, smoke release and toxicity and flame spread through dripping.

Paxymer FR-functionality: low heat release rate, stabilizing, non-dripping and low smoke toxicity.

Paxymer FR-functionality: low heat release, stabilizing, non-dripping and low smoke toxicity.

Paxymer is a multi-mechanistic system that acts as a stabilizer in the condense and gas phases. Our unique flame retardant mechanism propagates crosslinking of the polymers at high temperatures (>500°C). The system has several benefits in a fire situation:

Low heat-release rate limits flame spread and increases the time to flashover. Paxymer reduces the heat release rate to <200 kW/m2, a 3-5 time reduction compared to a virgin olefin and 2-3 time reduction compared to brominated systems. Heat release rate is considered in burning standards for building and shipping such as EN-13501, EN-5660 and DIN 4102.
Low smoke toxicity. Fire deaths are commonly caused by toxic smoke. Paxymer emits very low to no levels of CO and CO2, NOx, SOx and HCN. Paxymer is also free of corrosive gases such as HCl and HBr.
Non-dripping behavior limits flame spread and re-ignition of other material in a fire situation. Paxymer’s unique crosslinking mechanism achieves non-dripping by using functional polymers. It is completely free of salts, flouropolymers and other conventional solutions.

Excellent Processing Properties

Paxymer achieves excellent mechanical performance through our unique multi-mechanistic system design. Good compatibility and dispersion in our master batches makes addition of Paxymer straight into the conversion (e.g. injection molding or extrusion) process possible without significant loss of mechanical properties.

Paxymer has experience of almost all plastic processes and currently have products on the market within the following processes:

Extrusion – compounding and converting
Injection moulding
Blow moulding.

Examples in the following tables are from customer projects. These examples do not represent the limits of the product, rather they give an idea of what has been done in other projects. Selection of base polyolefin material and processing properties has a significant impact on mechanical properties.
