The cable jacket is the outermost layer of the cable. As the most important barrier to protect the safety of the inner structure of the cable, it protects the cable from mechanical damage during and after installation. Cable jackets do not require replacement of reinforcements inside the cable, but they can provide a high level of but limited protection. In addition, the cable jacket provides water, chemical, UV and ozone protection. So, what is the material of the cable jacket? PVC cable material is made of polyvinyl chloride as the basic resin, adding stabilizers, plasticizers, calcium carbonate and other inorganic fillers, additives, lubricants and other additives, mixed, kneaded and extruded particles. Polyvinyl chloride can be prepared and used in a variety of environments and applications. It's low cost, flexible, fairly strong, and fire/oil resistant. PE polyethylene is widely used as a coating material for wires and cables because of its excellent electrical insulation properties and good processing properties, mainly for the insulation layer and sheath layer of wires and cables. Polyethylene is hard, but low-density PE (LDPE) is more flexible, has excellent moisture resistance, and PE has excellent weather resistance when prepared properly. The linear molecular structure of polyethylene makes it easy to deform at high temperatures. Therefore, in the application of PE in the wire and cable industry, polyethylene is often cross-linked into a network structure, which makes it highly resistant to deformation at high temperatures. The insulation materials of wire and cable are cross-linked polyethylene (XLPE) and polyvinyl chloride (PVC). PURPUR cable is one of those cables. The material of PUR cable has the advantages of oil resistance and wear resistance, while PVC is made of ordinary materials. In the cable industry, polyurethanes have become increasingly important over the past few years. At certain temperatures, the material has mechanical properties similar to rubber. TPE thermoplastic elastomers are obtained through the combination of thermoplasticity and elasticity. Widely used in industrial machinery and equipment, transmission control systems, various industrial sensors, testing instruments, electronic equipment, household appliances, electromechanical, kitchen and other equipment, for power and signal connections in harsh environments, oil-proof and other occasions. TPE/TPR. Thermoplastic elastomers have excellent low-temperature properties without the expense of thermosets. It has good chemical and oil resistance and is very flexible. Good abrasion resistance and surface texture, but not as durable as PUR. TPU polyurethane cable refers to a cable that uses polyurethane material as insulation or sheath. Its super wear resistance refers to the super wear resistance of the cable sheath and insulation layer. The polyurethane material used in cables is generally called TPU, which is a thermoplastic polyurethane elastic rubber. Mainly divided into polyester type and polyether type, hardness range (60HA-85HD), wear-resistant, oil-resistant, transparent, and good elasticity. TPU not only has excellent high wear resistance, high tension, high tension, toughness and aging resistance, but also is a mature environmental protection material. The application fields of polyurethane sheathed cables include cables for marine applications, cables for industrial robots and manipulators, cables for port machinery and gantry cranes, and cables for mining engineering machinery. Themoplasticcpe. Chlorinated polyethylene (CPE) is often used in very harsh environments. It has the characteristics of light weight, very hard, low coefficient of friction, good oil resistance, good water resistance, chemical resistance, UV resistance and low cost. Ceramicized silicone rubber. Ceramic silicone rubber has excellent fireproof, flame retardant, low smoke, non-toxic and other characteristics. , and the extrusion molding process is simple. What remains after burning is a hard ceramic shell that will not melt and drip in a fire environment. At a temperature of 950°C-1000°C, it can pass the GB/T19216.21-2003, cooling 15min circuit integrity test. Ceramic silicone rubber products have no special requirements for equipment, and the processing technology is simple. It can be produced by conventional silicone rubber processing equipment. Compared with the current production process of fire-resistant wire and cable, the production efficiency is higher, which can reduce production energy consumption and save costs. All of the above are the materials for the cable sheath. In fact, there are many types of cable jackets. When selecting the raw material of the cable sheath, the compatibility of the connector and the adaptability to the environment should be considered. .
