| NEOPRENE / CHLOROPRENE (CR) | ||
| Ethylene-acrylic (Vamac ®) is a terpolymer of ethylene, methyl acrylate, and an acid-containing monomer as a cure site. It exhibits properties similar to those of Polyacrylate, but with extended low temperature range and with enhanced mechanical properties. Ethylene-acrylic offers a high degree of oil, ozone, UV and weather resistance. Neoprene has excellent adhesion qualities to metals for rubber to metal bonding applications. It is used extensively for sealing refrigeration fluids due to its excellence resistance to Freon® and ammonia. |
