As an important wire assembly product, PE wire harness is widely used in automotive manufacturing, aerospace, home appliances, electronic products, medical equipment, communication equipment and industrial automation fields. Its good insulation performance, wear resistance, waterproof performance and other characteristics, for various industries to provide a stable and reliable wire connection solutions.
 
 However, the excellent chemical stability of PE also makes it difficult to assemble and seal the material. Engineers found that when the commonly used glue is used in the PE material, it even easily falls off, with almost no "stickiness". What should we do?
 
 Seeking a special preparation method of adhesive and sealing adhesive water for PE and other high-density materials is a technical problem that many glue manufacturers want to break through. Xiaobian believes that, in the final analysis, but also have to solve from the raw materials. Therefore, xiaobian listed for you to make 3 breakthroughs from raw materials, can firmly stick to PE wire harness methods, each of which is effective oh.
 
 PE wire harness bonding method 1: British Chemical invented a rubber called S-PERMEATE RUBBER, which has a smaller molecular grade, can easily penetrate into the surface of high density material, produce firm adhesion to it. As the raw material of glue, it is used to bind difficult materials such as PE, HDPE, PP, EVA, PA6, POM and so on. ENIENT ®EG1023 Glue uses the bond force between molecules to form a stable and reliable adhesion for high surface energy materials. This kind of modified rubber glue has been very mature, not only has a stable and reliable long-term adhesion, and has elasticity, toughness, high waterproof sealing.
 
 Get the PE wire harness bonding method 2: treatment agent + UV glue. There is no way to form an effective attachment to PE by using UV glue alone. The medium-type treatment agent can form an auxiliary bonding layer on the PE surface, which enhances the adhesion of UV adhesive to PE. But this method will be more troublesome to operate, the efficiency is also relatively low.
 
 Get the PE wire harness bonding method 3: treatment agent + modified siloxane glue. Silicone has limited adhesion to PE surface, while modified siloxane glue can only have 0.2~0.3MPa peel resistance to PE surface. However, with the combination of the special treatment agent, the final sealing force can reach about 1.5 Mpa, which is enough for the general strength seal. And the modified siloxane glue has good resistance to damp heat aging and ultraviolet resistance. Similarly, the operation is more troublesome, the same is its unavoidable shortcomings.
 
To sum up, there are a variety of ways to effectively fix the PE line, which method do you think is the best? Xiaobian believes that efficiency first, can without the bottom coating and treatment agent, directly stick PE firmly, perhaps more meaningful for many manufacturers. What do you think?
