Proxxima™ polyolefin thermoset resin systems are compatible with fillers and fibers, enabling Promens Zlin to expand its product portfolio with lightweight, low-carbon-footprint of product, high-toughness polymer and composite solutions.

Where can the benefits of Proxxima™ resin systems be applied? Examples from the TRUCK segment.

Performance That Makes a Difference

1. Lightweight yet Strong

– Ideal for reducing weight in vehicles, infrastructure, and energy storage systems.

2. Exceptional Toughness

– Damage resistance and excellent material behavior under load ensure a long durability
– Interlaminar fracture toughness 5x greater than epoxy
– Fatigue resistant

3. Fast and Efficient Processing

– Fills RIM molds in seconds, curing in under a minute.

Processing Technologies:
RIM (Reaction Injection Molding): for products up to 25 kg
RTM (Resin Transfer Molding): for high-performance composite components

4. Water and Chemical Resistance

– Very low water absorption and excellent long-term performance in wet, hot, or corrosive conditions.

5. Lower carbon footprint of product (CFP) estimate

– Proxxima resin systems has a CFP estimate ~60% lower than comparable epoxy resin on a cradle-to-gate basis*
