What You Need To Know About PORON® Urethane Foam

For over 30 years, CB Frost has maintained a close relationship with world leading speciality engineered materials company, Rogers Corporation. We are a preferred UK converter of Rogers products, including PORON® Urethane foam. 

PORON® Urethane is an industrial polyurethane foam that is known for its compression set resistance. Its open cell or semi closed cell design ensures that it keeps its shape, softness, flexibility and cushioning throughout its lifetime, even through multiple impacts. After poron is subjected to pressure, it will expand to return to its original size and shape, or at least until it meets a new pressure or impact. As a result, it can be an extremely dependable material for use in a wide range of applications across many industries.
