HT-70UL is a low density, high temperature closed cell foam for industrial applications.

A significant improvement over traditional PVC products, Foam Seal HT foams outperform more expensive alternatives. HT-70UL is a cost-effective replacement for EPDM.

As a UL94 approved component in electrical applications, HT-70UL conforms to UL 94 HF-1 and is a recognized component of Underwriters Laboratories. While HT-70 UL is used for applications requiring (UL 94 HF-1) conformance, that does not automatically transfer UL ratings to the customer’s product. It remains pliable at temperatures of -34°C to 110°C (-30°F to 230°F).

HT-70UL can be classified to 2B0 as specified by ASTM D-1056.

This Foam Seal UL Approved PVC foam is sulphur free, low VOC, certified Prop 65 compliant, and resistant to UV, petroleum, & cleaning solutions.

We manufacture to your specifications. Available in 1/16” to 3/8” gauges, HT-70UL has a shelf life of 6 months with adhesive and 2 years without adhesive when stored at or below 75°F.
