Urethane Potting Products

EFI Polymers’ urethane potting and encapsulation products offer a number of advantages. Urethane potting performs well in low temperatures, is very flexible, and adheres well to plastics. It is ideal for electronic applications, surface mount technology, and when thermal cycling resistance is a requirement. Low elastic modulus, ideal CTE values and low glass transistion temperature ensure that the urethane potting performs optimally across a wide range of temperatures. Please contact us for more details and product specifications.
