Your Leading CPE Tube Manufacturer
Weprofab’s CPE tubes have many excellent properties, such as high temperature resistance, wear resistance, and corrosion resistance, and are widely used in automobiles, electrical appliances, industry, and other fields.
At the same time, our CPE tube can also change its physical and chemical properties by adding different amounts of chlorine to meet different uses. In addition, you can also customize CPE tubes of different thicknesses and lengths according to your needs.
Various Types of CPE Tube
Low-chlorine CPEThe chlorine content of low-chlorine CPE is between 25%-30%, with good flexibility and UV resistance, and easy processing.
Medium-chlorine CPEThe chlorine content of medium-chlorine CPE is between 30%-40%, with excellent flexibility and impact resistance, and can withstand moderately corrosive environments.
High-chlorine CPEThe chlorine content of high-chlorine CPE is between 40%-45%, with strong flame retardancy and thermal stability, and can withstand high temperatures of 150°C for a short time.
Cross-linked CPECross-linked CPE is cross-linked by sulfur or peroxide, can be used at high temperatures of 135°C for a long time, and has anti-compression properties.
Blended modified CPEAfter CPE is blended with PVC, the impact strength of the notch can reach 5-10 times that of ordinary PVC. And it has good oil resistance.
Excellent Properties of Weprofab CPE Tube
Excellent Properties of Weprofab CPE Tube
Physical properties: Weprofab CPE tube can withstand temperatures from -40°C to 120°C, has good thermal stability, and is not easy to decompose at high temperatures. Our CPE tube has the characteristics of automatic extinguishing when away from fire, and does not release toxic gases when burning. It also has good flexibility and wear resistance.
Chemical properties: Weprofab CPE tube can resist corrosion from strong acids, strong alkalis, salt solutions, oils, alcohol ester organic solvents, and oxidants. Our CPE tube has strong anti-aging properties and is not prone to aging and deformation even if exposed to a large temperature difference for a long time.
Various Applications of Weprofab CPE Tube
Wire and cable sheath: Weprofab CPE tube is often used to manufacture oil-resistant cables and electrical cable sheaths due to its excellent flame retardancy, good insulation, and excellent aging resistance.
Industrial hose: Weprofab CPE tube is often used to manufacture chemical delivery hoses and hydraulic hoses that are resistant to acid, alkali, and organic solvents due to its good corrosion resistance, excellent pressure resistance, and excellent wear resistance.
Auto parts: Weprofab CPE tube is often used to manufacture fuel pipes, cooling pipes, and seals due to its excellent high temperature resistance, good oil resistance, and excellent compression resistance.
How to produce a CPE tube?
The production of a CPE tube requires the following steps.
Step 1: You should chlorinate polyethylene in hydrochloric acid, control the chlorine content between 25%-45%, and synthesize CPE resin.
Step 2: You can mix CPE with PVC, plasticizers, etc. to improve the impact resistance of the CPE tube.
Step 3: You should heat the mixture to a molten state of 160-200°C, and then extrude it into a ring mold through an extruder to form the tube.
Step 4: You should use water cooling or other cooling methods to quickly cool the CPE tube to keep the size of the tube stable.
Step 5: You should test the density, chemical resistance, impact strength, and other properties of the CPE tube, and finally cut it into the required length.
How to package and store the CPE tube?
Packaging: You should use composite woven bags or PE plastic film to wrap the CPE tube, and seal the ends of the tube with plastic covers or tape to prevent dust and moisture from entering. Small-diameter tubes can be fixed with strapping tape, and each bundle has the same length to prevent rolling during transportation. Large-diameter tubes can be supported by wooden or steel frames, and corner guards should be added to the edges to prevent collision and deformation. In addition, you should indicate the product specifications, production date, and warning signs such as “moisture-proof” and “light-proof” on the outer packaging.
Storage: You should store CPE tubes at a temperature between -10°C and 40°C and a relative humidity of ≤70%. And be careful not to place the CPE tube in direct sunlight, and it needs to be covered with UV-proof tarpaulin. In addition, you should place the CPE tube flat on the ground or a pallet, not upright.
