High Resilience foam, or HR foam, is open-cell, flexible polyurethane foam that has a less uniform (more random) cell structure that helps add support, comfort, and resilience or bounce.hile HR foams are a significantly smaller part of what Bergad offers, we do offer foams in a wide range of physical characteristics, with: 1  Densities from 2 to over 30 pounds per cubic foot, 2  Firmnesses (25% IFD) from 15 to over 300 pounds,
It can be used in many of the same applications as acrylic when impact strength is a factor. Some common uses are as safety shields and enclosures, sight glasses and chair mats. PVC Polyvinyl Chloride. PVC sheet is medium impact, high corrosion resistant material, ideally suited where chemical resistance is necessary.VDF Polyvinylidene Fluoride PVDF, manufactured under the names of Kynar and Hylar, is a high performance thermoplastic that combines great mechanical strength and high abrasion resistance with a broad temperature range. It is highly resistant to most environmental conditions and corrosive materials.
