Why Us
Advantages of our Polymer materials:
Our product is a direct replacement for many foam EPDM components and, as shown in the table below, provides the OEM with many advantages.
| RPM PolyGreen™ | EPDM | |
| Common Properties | ||
|
Temperature Resistance |
Addition polymerization provides minimal dimensional reduction Flexibility when exposed to temperatures extremes Provides dimensional stability | Free radical polymerization causes shrinkage Vehicle operating temperatures allow additional curing and IFD loss |
|
Chemical Resistance |
High resistance to engine fluids (such as oils, brake fluids) | Minimal - EPDM is dissolved by petroleum based fluids |
|
Physical Properties |
Consistency of physical properties during life of product 15lbs./ft3 density | Incremental increase in durometer 25lbs./ft3 density |
| Inherent Characteristics | ||
|
Compression Deflection |
Static fatigue resistance | Degradation of compression set properties |
| NVH | Optimum NVH properties realized via uniform microcellular cell structure & micronized recycled rubber particles | Large voids and non-uniformity allow transmission of vibrations |
|
Biological Activity |
Naturally resistant to attack Resistance boosted by EU approved biocide | Promotes fungal and bacteria growth. High temperature processing limits biocide use |
| Environmental Impact | >25% Recycled Rubber reduces landfill use. Weight reduction via lowering of the density. Minimization of energy consumed and subsequent emissions. Blowing agents are non-CFC. | |
| Additional Issues | ||
| Economics | Minimization of utilities consumed via Manufacturing process 10 - 20% typical cost advantage | |
| Safety | Known carcinogen - crystalline silica is present on parts | |
