Materials

1201

Our 1201 neoprene material is a 8 – 15 PCF / 128 – 240 kg/m³ black closed cell foam listed to UL 50 JMST2. This foam is a SBE41/SC1 grade, which is an excellent choice for sealing NEMA 250 rated enclosures. This foam is also used in other electrical sealing and general gasket applications requiring protection from foreign materials and water. 1201 has a temperature range of -40 F to 200 F. It has a Fluid Immersion rating of 250% and a Resilience rating of 50. It also has good Ozone resistance and a Rebound Average of 40-50%.
