| This high performance polyester microcellular foam system is one of a family of polymer systems developed by Northstar Polymers for demanding work environments. Urethane foams molded with this system exhibit high tear strength, excellent oil resistance, and outstanding abrasion resistance. They also meet the requirements of 21 CFR 177.1680, FDA direct dry food contact. When the packing factor exceeds 1, an integral skin will develop with properties approaching those of the cast elastomer. For long-term use in constant aqueous environments, consider a polyether or hybrid product system.Information provided by Northstar Polymers. |
