WESTBURY, England—SPC Europe Ltd. has developed new formulations for the manufacture of closed-cell expanded EPDM materials with a premium density as low as 0.3.
The sponge products exhibit excellent elastic recovery and are especially lightweight with good waterproof properties, according to an SPC news release.
"We have developed new technology in both formulation and compounding for these specific recipes," SPC Technical Manager Bhawan Patel said in a statement. "Some of the technology was only introduced last year and has enabled us to develop a product with a smoother skin and achieve lower density than seen before."
Target applications include door seals and other parts requiring weight-saving in the automotive industry as well as weatherproofing products for the construction industry.
Citing customer feedback, Bhawan said the material has been found to form a particularly smooth surface-skin and provide a strong air and watertight barrier, which helps to prevent build-up of bacteria or mold.
