Rubber compression set; compression set device

1. Overview of rubber compression permanent deformer:
The permanent compression deformer is composed of parallel steel plate limiters and fasteners, meets the requirements of B., and is used for vulcanized rubber, thermoplastic rubber at normal temperature, high temperature and low temperature conditions. Under a certain compression rate, the amount of rubber deformation is measured after a certain compression time.

Purpose and Features: The tester consists of parallel steel plates, limiters and fasteners, and meets the requirements of B. At a specified temperature, the foam material sample is allowed to maintain constant deformation for a certain period of time. After the sample recovers for a period of time, the effect of the deformation on the test thickness is observed. The compression permanent deformation of the material is expressed as a percentage of the difference between the initial thickness and final thickness of the specimen and the initial thickness of the specimen.
