[0002] Thermoplastic elastomers (TPE / TPR), also known as synthetic rubber or artificial rubber, possess the excellent properties of traditional cross-linked vulcanized rubber, such as high elasticity, aging resistance, and oil resistance, while also having the advantages of ordinary plastics, such as convenient processing and a wide range of processing methods.

[0003] For example, Chinese patent application CN202321939657.5 discloses a thermoplastic elastomer aging performance testing device. The specific details are as follows: The thermoplastic elastomer to be tested is placed on a rotating connecting plate after the cover is opened. Particulate thermoplastic elastomers are placed between guide columns, which clamp and fix the particulate elastomers under the action of springs. Block-shaped thermoplastic elastomers can be placed on a placement plate. The cover is then closed, and the heating wire and ultraviolet lamp are activated. The heating wire tests the aging of the thermoplastic elastomer under different temperature conditions, while the ultraviolet lamp simulates sunlight exposure to detect the sunlight aging of the thermoplastic elastomer. During heating and irradiation, the motor output shaft rotates, driving the rotating connecting plate to rotate via the connecting rotating column. This rotation of the rotating connecting plate causes the connecting column and placement plate to rotate, ensuring that the thermoplastic elastomer undergoing the aging test is rotated and uniformly heated and irradiated.
