With overcapacity and increased competition, the development of many PVC power line companies across the country has encountered bottlenecks. It is understood that rubber wire and cable will replace PVC power cords in the next decade, which will light up the future for Chinese rubber wire and cable companies.
The anti-aging performance of rubber wire and cable is thousands of times better than PVC power cord, which not only increases the use time, improves safety, but also maintains soft use performance at low temperatures and maintains good insulation performance at high temperatures. Rubber wire and cable will have a wider application in outdoor waterproof power tools, LED lighting, home and industrial pump industry, automotive and other fields. The industry believes that "a rubber wire and cable, no problem after 10 years of use." But because the price of PVC power cord is lower than the price of rubber wire and cable, the application rate is not high, but the future is a big trend.
When it comes to the problem of China's PVC power line companies being forced to transform or even close down in recent years, the industry believes that many PVC power line companies in China have serious homogenization problems and lack of advantages in competition. “Like China’s steel companies, Overcapacity will lead to price declines, and in a freely competitive market, a natural elimination mechanism will emerge."
At the same time, the benefits of wire and cable manufacturing companies are also closely related to whether materials can be scientifically saved in material selection, processing and production management.
Therefore, when designing rubber wire and cable products, it must be carried out simultaneously with the selection of materials. Generally, several materials are selected, which are determined through process and performance screening tests.
The materials for cable products can be divided into conductive materials, insulating materials, filling materials, shielding materials, and sheath materials according to their use parts and functions. However, some of these materials are common to several structural members. In particular, thermoplastic materials such as polyvinyl chloride, polyethylene, etc. can be used on the insulation or sheath as long as some of the formulation ingredients are changed.
