VFI®-3150 50 A MDI Fast Molding Rubber

VFI®-3150 50 A MDI Fast Molding Rubber is a 50 A hardness, urethane rubber that provides high durability and flexibility with a shortened demold time. With the ability to maintain a thin viscosity long into its pot life, VFI-3150 allows for intricate parts to be poured with consistently thin material and large parts to be poured quickly. Maintaining a low viscosity allows VFI-3150 Fast Molding Rubber to dissipate air bubbles with and without vacuum degassing depending on application.

50 A MDI mold making rubber with a quick demold time and a low viscosity.
