VFI®-3161 60 A MDI Molding Rubber

VFI®-3161 60 A MDI Molding Rubber is a 60 A hardness urethane rubber that provides high durability and flexibility. With the ability to maintain a thin viscosity long into its pot life, VFI-3161 allows for intricate parts to be poured with consistently thin material and large parts to be poured quickly. Maintaining a low viscosity allows VFI-3161 Molding Rubber to dissipate air bubbles with and without vacuum degassing depending on application.

60 A MDI mold making rubber with a slow pot life for easier mixing and a low viscosity for easier pouring.
