| POLYACRYLATE (ACM) | ||
| 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. |
