| RTP Engineering Plastics/ 40% Glass Fiber Rigid Thermoplastic Polyurethane RTP 2037A | ||
| RTPU is an engineering thermoplastic material based on urethane chemistry. It is not an elastomer, but is amorphous, which signifies that the material will mold to a tight dimensional tolerance without warping. Its chemical resistance is similar to a semi-crystalline material. RTPU has high impact strength and is very light grey in color. | ||
| APPLICATIONS | ||
| Applications include agricultural and irrigation components, recreation and automotive equipment and electrical connectors. | ||
