SWP™ application idea Highly durable urethane foam
Urethane foam modified with SWP™ is highly durable. The compression residual strain is reduced by 70%, leading to a longer usage life of the urethane product.*

Conceptual diagram of interaction of SWP™ and urethane molecules
- SWP™ can be dispersed in and combined with raw material liquids. It can be introduced into the urethane matrix without affecting reactions.
- SWP™ is made of polyethylene and has lower density than glass fiber and similar fibers, making it highly effective for weight reduction.
- SWP™ captures particles in the urethane matrix and in foam bubbles while imparting a stabilizing effect.
- SWP™ effectively contributes to slab urethane strength.
