What materials are available for cable jacketing?

I. What are the materials used in cable sheathing? The cable sheath is the outermost layer of the cable. It serves as the most important barrier for the safety of the internal structure of the cable and protects the cable from mechanical damage during and after installation. Cable jackets do not require the replacement of reinforcements inside the cable, but they provide a high but limited level of protection. In addition, cable jackets provide water, chemical, UV, and ozone protection.1. PVC: Cable materials are pellets made by mixing, kneading, and extruding polyvinyl chloride (PVC) as the basic resin with stabilizers, plasticizers, inorganic fillers such as calcium carbonate, additives, lubricants, and other additives. Polyvinyl chloride can be prepared and can be used in a variety of environments and applications. It is low cost, flexible, fairly strong, and fire/oil resistant.2. PE: Polyethylene is widely used as a coating material for wires and cables because of its excellent electrical insulating properties and good processability, and is mainly used for insulation and sheathing of wires and cables. Polyethylene is very hard, but low density PE (LDPE) is more flexible, moisture resistance, properly prepared PE has excellent weather resistance. The linear molecular structure of polyethylene makes it susceptible to deformation at high temperatures. Therefore, in the application of PE in the wire and cable industry, polyethylene is often transformed into a mesh structure through cross-linking, making it highly resistant to deformation at high temperatures. Cross-linked polyethylene (XLPE) and polyvinyl chloride (PVC) are used for the insulation of wire and cable.3. PUR: PUR cable is one of the cables.The material used for PUR cables has the advantage of oil and abrasion resistance, while PVC is made of common materials. In the cable industry, polyurethane has become increasingly important in the last few years. At certain temperatures, the mechanical properties of this material are similar to those of rubber.TPE thermoplastic elastomers are obtained by combining thermoplasticity and elasticity.4. TPE/TPR: Thermoplastic elastomers have excellent low-temperature properties without the expense of the capital required for thermoset materials. It has good chemical and oil resistance and is very flexible. Good abrasion resistance and surface texture, but not as durable as PUR.5. TPU: Polyurethane cables are cables that use polyurethane material as insulation or sheath. Its super abrasion resistance refers to the super abrasion resistance of the cable sheath and insulation. The polyurethane material used in cables is generally called TPU, which is thermoplastic polyurethane elastic rubber. It is mainly classified into polyester type and polyether type, with hardness range (60HA-85HD), abrasion-resistant, oil-resistant, transparent, and elastic.TPU not only has excellent high abrasion resistance, high tensile strength, high tensile strength, strong toughness, and aging resistance, but also is a mature environmentally friendly material.6.Themoplasticcpe: Chlorinated polyethylene (CPE) is usually used in very harsh environments. It is lightweight, very hard, low coefficient of friction, good oil resistance, good water resistance, chemical resistance, UV resistance, low cost, etc. 7. Ceramicized Silicone Rubber: Ceramicized Silicone Rubber has excellent fire resistance, flame retardant, low smoke, non-toxicity. , and the extrusion molding process is simple. The residue after combustion is a hard ceramic shell, which will not melt and drip in the fire environment. Under the temperature of 950℃-1000℃, it can pass GB/T19216.21-2003, cooling 15min line integrity test.
