As polytetrafluoroethylene (PTFE) has strong corrosion resistance, stable performance, resistance to aging, low friction coefficient, easy forming, and stable size, it can also be filled and added with appropriate materials to improve its comprehensive performance, and obtain butterfly valve sealing materials with better strength and lower friction coefficient, overcoming some limitations of synthetic rubber, As a result, polymer materials represented by polytetrafluoroethylene and their filling modification materials have been widely used in butterfly valves, which further improves the performance of butterfly valves. Butterfly valves with wider temperature and pressure ranges, longer sealing performance and service life have emerged.

Industrial properties of plastic coated hoses?
The inner layer of plastic coated hose is made of stainless steel hose or galvanized hose and special insulation treatment, and the outer layer is made of PVC material (UV resistant and anti-aging).
1、 Product color
Black, gray and other colors are available.
working temperature
-40℃~+160℃ 。
Product characteristics
1. The plastic coated hose has excellent waterproof, insulation and tensile properties.
2. PVC materials are used for the surface of plastic coated hose, and fire retardant is added to the PVC plastic.
3. The plastic coated hose is of single button and double button structure, which increases the tensile strength and is not easy to break or deform.
4. The plastic coated hose has good bending performance and smooth internal structure, which is easy to pass when threading wires and cables.
5. The plastic coated hose is waterproof, oil and corrosion resistant, and has good sealing performance. The products have beautiful appearance and tight structure, and are widely used in the wire and electrical appliance maintenance of fine instrument wiring, power, wire, plastic, rubber and other industries.
2、 Application category
