How to solve the phenomenon that the Neoprene Zipper Cable Sleeve becomes hard and brittle?

Neoprene Zipper Cable Sleeve is one of the most widely used products in the electronics industry. It is mainly used for sensing and conducting heat. It is one of the best materials specially selected for transferring heat through gaps. It can fill gaps, pass through the channels of heat-generating parts and heat-dissipating parts, and can effectively improve the efficiency and stability of the heat transfer system, and use Cable Sleeve to achieve certain insulation, shock absorption, sealing and protection functions. It can meet the needs of various small and medium-sized electronic equipment with good heat conduction system. It is a relatively traditional type of heat conduction filling material at present.

However, in the actual use process, there are also different product quality problems. The more common ones are the failure of thermal conductivity sensors and the decline in product aging life. Among these problems, the problem of aging life is the main factor. What are the phenomena that affect the service life of the zipper cable sleeve?
1. What does "aging and hardening" of Neoprene Zipper Cable Sleeve mean?
During the use of silicone Neoprene Zipper Cable Sleeve, due to the long-term high temperature environment, the hardness will increase, which will seriously affect the use effect and service life of the gasket, and will also cause damage to electronic and electrical equipment .
Therefore, the user will conduct an aging test on the product. Different manufacturers and different applications will have different standards. A common method is to bake at 150°C for 72 hours to compare the hardness before and after baking.
2. What are the hazards of Neoprene Zipper Cable Sleeve hardening later?
Since this type of thermally conductive material is mostly used in sophisticated electronic and electrical products, once such problems occur, the common hazards are as follows:
①After the gasket becomes hard, it is not only inconvenient for construction, but also reduces the fit, seriously increases the thermal resistance, and reduces the heat dissipation effect.
②If it hardens after construction, the gasket itself is easy to crack or even pulverize, the life of the gasket will be shortened, and the heat dissipation effect will be seriously reduced at the same time.
③In the later stage of hardening, the gasket and the protected components will be separated, resulting in the direct exposure of the components, which will easily cause product short circuit or thermal oxidation, rust, etc., and affect the life of the components.
