The hose is divided into single, double, and five-layer hoses. Among them, the double-layer pipe is more commonly used, and the middle and low-end general-purpose single-layer hoses are used. The hose cover is an injection molded product, and the hose is a pull tube. Most hose manufacturers do not produce hose covers themselves.
Material is usually PP, PE, K material, AS, ABS, acrylic, PET and so on.
PET material is an environmentally friendly material. It is widely used in mounting gel water. among them:
Acrylic materials are injection molded bottles, which have poor chemical resistance. Generally, they cannot be filled with paste directly. They need to be filled with an inner baffle to prevent the filling from becoming too full and prevent the paste from entering between the liner and the acrylic bottle. Cracking, high packaging requirements during transportation, as a result of scratches look particularly obvious, high permeability, sensory upper wall thickness, but the price is quite expensive.
AS, ABS: AS transparency is better than ABS, and toughness is better.
