Abstract:
The present invention relates to a scratch resistant polymer composition having a polymer that includes a copolyetherester elastomer, said polymer having a hardness of from 25D to 82D, and a fluorosurfactant having a nonionic organic head and a tail of the formula CF.sub.3 --(CF.sub.2).sub.x --CH.sub.2 CH.sub.2, where x is an integer from 3 to 15.
Abstract:
Disclosed herein is a process for heat treating a foamed copolyester thermoplastic sheet structure in order to achieve a sheet structure having a compression set resistance (as determined according to ISO 1856, 22 hours, 70° C., 30% compression) of less than 11%. Heat treating involves annealing followed by at least two cycles of pre-compression at approximately the annealing temperature.
Abstract:
Jounce bumper (14) comprising a shock absorber with a cylinder and a slidable piston rod (12), the jounce bumper (14) including an elastically compressible bumper portion (24), a mounting portion (18) and an axially extending central bore (15) positionable around the piston rod. The mounting portion (18) comprises a plurality of flexible locking legs (26) configured for insertion through an orifice (32) of a structural element (16) of the suspension system, the flexible locking legs comprising locking protrusions (36) with retaining shoulders (39) configured to engage an edge (33) of the orifice in a locked position. The locking legs have radially inwardly directed cam protrusions (38) configured to be engaged by the piston rod and are movable from an intermediate position after insertion through the structural element orifice to a locked position after insertion of the piston rod through the jounce bumper central bore.
