What is the maximum operating temperature of the foam?

Polyethylene has a melting point around 110°C (230°F). As we cross-link our product, this enhances the thermal stability but as you approach this temperature the foam will tend to shrink at an increasing rate.

Zotefoams datasheets are based on a specific 24 hour test for 5% shrinkage of a foam piece. Many variables affect shrinkage such as time, temperature, dimensions, humidity, cell size, density, application of a load and even colour. We advise testing and measurement to ensure the correct material is selected.

ZOTEK foams, based on advanced polymers have considerably higher working temperature limits than do polyolefin foams. ZOTEK N, based on polyamide (nylon) has an upper limit some 100C higher than similar density polyethylene foams.
