Heat Shrinkable Cable Accessories Polymer Memory Material

2022-04-26
Heat shrinkable materials are also called polymer shape memory materials, which have shape memory function through irradiation crosslinking. When heated above the crystallization temperature, the colleague expands to a specific shape and is cooled rapidly, the corresponding heat shrinkable product is made. Heat Shrinkable Cable Accessories as one of the main products of HUAYI CABLE ACCESSORIES Co.,Ltd., mainly suitable for 35kV and below medium and low voltage cable accessories, product specifications and models up to hundreds of. Through the continuous upgrading of product technology, we keep pace with The Times while meeting customer needs.

The production of heat shrinkable cable accessories needs to go through a series of processes such as mixing, forming, irradiation, expansion and gluing. The clever thing about heat-shrinkable materials is that they can remember complex shapes. Regardless of subsequent deformations, once the Heat Shrinkable Cable Accessories is placed at a certain temperature, it will return to its original "remembered" shape. It can be seen that "memory effect" is one of the basic principles for manufacturing heat-shrinkable products.

Heat sheinkable material is also called the shape memory polymer material, the material is through the Denamex accelerator of gamma rays, trigger a linear polymer molecules covalent bond between macromolecules, generation and accumulation into molecular weight a lot, with "memory effect" three-dimensional network structure, this process is called crosslinking, electrical and physical properties of the material can be greatly improved.

At present, the raw materials of Heat Shrinkable Cable Accessories produced by HUAYI CABLE ACCESSORIES Co.,Ltd. are mainly composed of six categories, such as EVA, PE, CPE, silicone rubber 110-2, antioxidant and flame retardant. The unique properties of these raw materials give the heat-shrinkable cable accessories good flexibility, flame retardant, high temperature resistance and excellent insulation performance. In the application of wire and cable, can play a good insulation, moisture-proof, sealing, protection and continuity.

The heat shrinkable products produced by HUAYI CABLE ACCESSORIES Co.,Ltd. have good heat shrinkable properties and excellent anti-aging properties. When EVA is mixed with PE resin and other polymers, high temperature resistant materials can be made. The heat-shrinkable products produced by HUAYI CABLE ACCESSORIES Co.,Ltd. are made by blending raw materials through the two processes of radiation crosslinking and heating expansion. The characteristics of the raw materials themselves make the products have corrosion resistance, high and low temperature resistance, heat shrinkage stability, electrical insulation and other properties. The technology enables the product to have thermal shrinkage performance. After being heated by the shrinkable device, it can be closely combined with the coating material with strong bonding strength.
