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