Creep Resistance of Plastics
Creep resistance can be defined as a material's ability to resist any kind of distortion when under a load over an extended period of time. For optimum performance and maximum lifetime, engineering plastics, which are subjected to long-term loading, should have a high creep resistance (i.e. low plastic deformation under load).
Creep behavior is also one of the factors that limit the maximum application temperature of a material. This table is an indication of which engineering plastic offer the best or worst performance, with 1 = Best in terms of Creep Resistance.
