Appearance judgment
The appearance of the casing pipe material is one of the most direct judgment bases. Qualified casing pipe materials should have a smooth surface, flat and free of defects such as bubbles, deformation or cracks. In addition, the printed words on the surface of the casing pipe should also be clearly visible.

Texture judgment
The texture of the casing pipe material reflects its protective strength and softness to a certain extent. Generally speaking, materials with higher hardness have stronger protection for wires, but their softness will also decrease accordingly. Materials with higher softness are relatively easier to install and use. Therefore, when choosing the casing pipe material, comprehensive consideration should be made in combination with specific needs.

Film thickness judgment
The greater the film thickness of the casing pipe material, to a certain extent, it represents a stronger protective ability. Therefore, when choosing the casing pipe material, you should try to choose a casing pipe with a more uniform film thickness and a thicker film thickness under the same material conditions.

Material selection
There are many types of casing pipe materials, such as PVC, PE, PET, etc. The specific choice of casing pipe material should be judged in combination with specific circumstances. For example, in Europe, PE casing pipe is widely used in various occasions and has become one of the best-selling wire casing pipes in the European market; while in the Chinese market, PE casing pipe is relatively less used, and PVC casing pipe is commonly used.

In short, it is very important to choose the casing pipe material that suits your needs. Judging by appearance, texture, film thickness, etc., can help everyone better understand and choose the casing pipe material, and provide stronger protection for wires and cables.
