Extra soft silicone wire is a kind of silicone wire with unique flexibility. The extra-soft silicone wire is wrapped with silicone for insulation purposes. Pvc wire actually means that the outermost material wrapped around the core material is made of polyvinyl chloride material. In a sense, it is also an insulated wire. So, how to distinguish extra soft silicone wire and pvc wire?

How to distinguish extra soft silicone wire and pvc wire

The difference between extra soft silicone wire and pvc wire:

1. Extra soft silicone wire

The extra-soft silicone wire has super high and low temperature resistance, high temperature resistance of 200 degrees, and low temperature resistance of minus -60 degrees. The outer skin is made of super soft and environmentally friendly silicone wire, which has no peculiar smell, is soft and can be bent at will, is not easy to harden, and is resistant to acid and alkali and has a long service life. The conductor is made of high-quality ultra-fine 0.08mm tinned copper, which has super strong anti-oxidation ability.

Extra-soft silicone wire is very soft, but the energy of silicon-oxygen bonds is much higher than that of carbon bonds in other rubbers, so it has superior heat resistance and cold resistance. The mechanical properties of silicone rubber are poor at room temperature, but when the temperature is above 150, the mechanical properties exceed other rubbers (including fluorine rubber). The electrical properties of silicone rubber vary little with temperature and frequency, and have good arc resistance and good thermal conductivity. But oil resistance and solvent resistance are poor.

When selecting extra-soft silicone wire, the heat generated by the loss of each part of the electronic wire should be considered, and the temperature of the electronic cable will not exceed its allowable temperature. In most cases, the transmission capacity of an electronic cable is determined by its allowable temperature. The allowable temperature of electronic cables mainly depends on the thermal aging performance of the insulating materials used. If the working temperature of the electronic cable is too high, the insulating material will accelerate aging, and the life of the electronic cable will be greatly shortened. If it is operated at the allowable temperature, the electronic cable can work safely for a long time.

2.PVC wire

Due to the superior physical properties and good flame retardancy of PVC materials, it has gradually been used more and more widely. Among them, it has been used as a wire insulator since the 1930s and 1940s. It is precisely because of the continuous improvement of the production capacity of pvc materials and industrial additives that the cable industry has made a qualitative leap.

pvc wire

The specifications of PVC electronic wires circulating on the market include UL1007, UL1061, UL1051, UL1571, etc. The internal conductors of PVC electronic wires should be divided into two types: bare copper and tinned copper according to normal standards. PVC insulated cables and wires are divided into unsheathed cables for fixed wiring, sheathed cables for fixed wiring, light unsheathed flexible cables, general purpose sheathed flexible cables, installation wires and shielded wires, special purpose sheathed flexible cables, Polyethylene insulated flame-retardant/fire-resistant cables and other products.

In terms of performance, PVC wire has many characteristics, such as good insulation and flame retardancy, which can prevent the occurrence of electric leakage due to short circuit and fault; good corrosion resistance, and relatively strong resistance to harsh natural environments Ability; durable, under the premise of protecting the wires, keep the wires away from external threats, thereby improving the service life of the wires; at the same time, the maintenance cost of pvc wires is relatively low.

When we buy extra soft silicone wire or pvc wire, first check whether the logo on the product (manufacturer name, factory address, model, specification, etc.) , scratches, bubbles, stains, etc., buy carefully.
