What is the difference between rigid and rigid and semi rigid in electric PVC plastic pipes?
The essence of PVC is a kind of vacuum blister film. It is used in the surface packing of various panels, so it is also called decorative film and adhesive film. It is applied to many fields such as building materials, packaging, medicine and so on. Among them, the building materials industry accounted for the largest proportion, 60%, followed by the packaging industry, as well as other small range of applications.
The hard PVC does not contain softener, therefore, the utility model has the advantages of good flexibility, easy molding, uneasy brittleness, no poison, no pollution and long storage time, so the utility model has great development and application value. Hereinafter referred to as "PVC".
PVC plastic pipes can be divided into soft PVC and hard PVC. Among them, hard PVC accounted for about 2/3 of the market, soft PVC accounted for 1/3. Soft PVC is generally used on the floor, ceiling and leather surface, but because soft PVC contains softener (which is also the difference between soft PVC and hard PVC), it is easy to brittle and difficult to preserve, so its range of application is limited.
