RTP 40% GLASS FIBER RIGID THERMOPLASTIC POLYURETHANE RTP 2307A (RTPU)
RTP 2037A 40% GLASS FIBER RIGID THERMOPLASTIC POLYURETHANE (RTPU)
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.
