Read the Rome Snowboard Binding Case Study bit.ly/34PG0a6 Incorporating Polystrand CFRTP reinforcement in molded thermoplastic components combines the design flexibility and fast cycle times of traditional molding with the strength, stiffness, and lightweighting benefits that composites offer, all with the use of standard processing equipment.

This is the best way to maximize long fiber performance and get the most benefit from material change.

Reduced total program life cost – The lightweighting and part consolidation benefits of using Therma-Tech material can help you achieve overall system cost reductions.
