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.

The key characteristics of PORON®

In addition to low compression set, important characteristics that make poron a versatile material for a vast number of applications are:

• Excellent impact and vibration absorption
• Low outgassing
• Temperature flexibility – able to withstand temperatures of between -40 and 90°C
• Good chemical resistance
• Available in different grades – including PORON® 4701-40 soft foam, PORON® 4701-50 firm foam for managing high energy impact and PORON® 4701-60 firm foam for energy management solutions including enclosure gaskets

Poron is well suited to a wide range of manufacturing processes to suit different applications. At CB Frost, we regularly die-cut poron urethanes into gaskets, strips or tape, washers and sheeting. It is also easy to fabricate, and can be combined with other materials for specialist applications.

Suitable applications

As a versatile material, poron is used for gaskets for automotive applications, LCD monitors and enclosures, as well as for sound and vibration absorption and dampening for a range of vehicles, as padding and cushioning for electronic applications, and even as shock absorption in shoes and athletic gear. 

At CB Frost, typical applications for poron include dust, water and non-fogging seals for lighting fixtures, and door panel seals for a range of vehicles, as well as cushioning for an extensive range of electronic and communications devices.
