We meet your production needs with a wide variety of potting compound formulations, and extensive experience in custom development.
We formulate and manufacture high performance polyurethane potting compounds that cure to provide a resilient, tough, electrometric coating that can insulate, protect, or bond.These polyurethanes provide: minimal ton o shrinkage, excellent adhesion, high dimensional stability, and optimum dielectric properties.
Properties can include: « High Performance « Low Tooling cost « Bonds to Steel, Rubber and Aluminum « Abrasion Resistant (Non-Marking) « Impact Resistant « Cut Resistant « Load Bearing « Flexible « Long Working Life « High Grip-Good Drive Material « Stable/ Low Outgassing « Oxygen & Ozone Resistant
Products are formulated and tested to maintain hardness and performance properties throughout the life of the substrate.

More about efi-polymers polyurethane potting compounds:
We serve original equipment manufacturers in America, Canada, Asia and Europe. The use of polyurethanes in the electrical and electronics industry is growing rapidly. Our polyurethanes are designed for ambient cured applications requiring good hydrolytic stability and low viscosity. The low initial viscosities and moderate gel times make these polyurethanes viable systems for both automated production or hand processing.
