1. want to really understand the super comprehensive performance of polyurethane, we must first understand what is polyurethane cable.

Polyurethane cable refers to the use of polyurethane materials as insulation or sheath of the cable, its super wear resistance refers to the cable sheath and insulation layer of super wear resistance. The polyurethane material used in the cable is generally referred to as TPU, which is a thermoplastic polyurethane elastomer rubber. It is mainly divided into polyester type and polyether type, with wide hardness range (60HA-85HD), wear resistance, oil resistance, transparency and good elasticity. It is widely used in daily necessities, sporting goods, toys, decorative materials and other fields. TPU not only has excellent high wear resistance, high tension, high tensile force, toughness and aging resistance, but also is a mature environmental protection material.

Characteristics of 2. polyurethane cable:

1, wear resistance

When the cable is often subjected to mechanical effects such as friction, scraping, and grinding during use, it will cause its surface to gradually wear, so the choice of materials is very important. TPU plastic raw material wear resistance is excellent, more than natural rubber (rubber cable) wear more than five times, is one of the materials of wear-resistant products.

2, tensile properties

The tensile strength of polyurethane cable is as high as 38MPa, and the tensile strength of ordinary rubber cable (one of the most common cables on the market) is only 8-12MPa. When the cable is applied in an environment with forced traction, the tensile effect of the rubber sheathed cable sheath is poor, and the core is easily broken after the wire core is subjected to external tension. The excellent tensile properties of polyurethane cable sheath and insulation have a good protective effect on the core, making it durable.

3. Tearing performance

Polyurethane cable in the application due to the expansion of the crack and the destruction is called tear, tear strength is the ability of the material to resist tearing; generally speaking, TPU has a high tear resistance, tear strength and some commonly used rubber comparison is very excellent.

4, flexural performance

Many plastic material cables (such as RVV) are prone to fracture under repeated periodic stress. Polyurethane cables can maintain excellent flex resistance in different environments and are one of the choices for repeated bending environments.

5, hydrolysis resistance

The water resistance of polyurethane cable is good under turbidity, and there will be no obvious hydrolysis within 1 to 2 years, especially the polyether series.

6, high temperature resistance and oxidation resistance

General plastic raw materials (PVC) are easy to oxidize in the environment above 70 ℃ for a long time, and TPU has good oxidation resistance. Generally speaking, TPU has a temperature resistance of up to 120 ℃.

7, oil resistance and drug resistance performance

TPU is a strong polar polymer material, and non-polar mineral oil affinity is very small, in fuel oil (such as kerosene, gasoline) and mechanical oil (such as hydraulic oil, engine oil, lubricating oil, etc.) is almost not corroded; Among them, polyurethane cable and polyester series of products with better oil resistance.

8, low temperature performance

Polyurethane cable has very good low temperature resistance, usually can reach -50 ℃, can replace the general PVC due to low temperature embrittlement and can not be applied in various fields, especially suitable for use in cold zone cable.

3. polyurethane cable application industry:

1. Industrial robots and manipulators

Industrial robots and manipulators special cable, which is characterized by a high degree of torsion resistance and repeated bending performance, the company developed and produced SLK series polyurethane cable, according to the characteristics of the equipment used,

In view of the anti-torsion performance and bending performance in-depth study of repeated experiments, and ultimately overcome the cable in the use of interrupted core, greatly improving the service life of the wire and cable. When the distance from the fixed fulcrum of the cable to the torsion end is more than 0.5M, the torsion angle can reach more than 360, the fastest instantaneous speed is 10 M/S, and the number of repeated bending can reach 15 million times. It is a domestic product that can replace imported robots.

2, port machinery and gantry crane drum cable

The reel cable is specially designed for the special cable of the control and power supply system of the reel. It is suitable for the occasions with high mechanical stress, especially tensile and torsional stress at the same time, and it is carried out with the guidance of the drag shaft or other similar devices. For example: motor-driven drum, spring control drum, lifting system and some frequent bending occasions such as woodworking machinery, machine tool processing equipment, logistics conveying system, crane occasions. The reinforcing elements integrated in the cable can withstand the tensile load and the gravity generated by high-speed operation. Because of its special structural design and special outer sheath material, the reel cable can be installed in dry or wet indoor industrial environment, and can also be used in the open air environment.

3, mining engineering machinery

Mining engineering machinery drag cables are suitable for all environmental requirements that require wear resistance, bending resistance, movement, winding, drag, waterproof, oil resistance, UV resistance, and low temperature resistance. In a special environment, its service life is any other material.
What the cable cannot achieve is more than 5 times the service life of the rubber sleeve cable, and the price is only about 3 times that of the rubber sleeve cable. However, the product value is extremely high, which is not only equivalent to the lowest cost in the service life, but also reduces the replacement trouble and delay of construction period caused by cable damage, and is more safe than ordinary cables. For example, in complex and harsh mines and tunnels, sharp stones have great damage to cables, and our special wear-resistant cables can resist this harsh working environment. For example, for hiking shoes with thousands of yuan abroad, the sole is made of the material of our cable sheath, and the wear resistance can be imagined.

In addition, the waterproof performance is also very excellent. The company has done a series of scientific experiments when developing this product. It can be soaked in room temperature water for a long time, up to several years, which is very suitable for working in a water environment.

4, wind power generation and offshore equipment use

Wind power stations are mostly built in open or high ground and offshore continental shelf where there is stable and strong wind all year round, and the cables used on wind power generation equipment built on mountains at higher altitudes are required to meet the requirements of resistance.
The performance of low temperature and severe cold, polyurethane cable fixed use the lowest temperature can be -60 ℃, while anti-aging, wind erosion resistance is excellent, is the use of wind power selection. The use of cables in offshore equipment requires cables to have high-strength UV resistance, corrosion resistance (weak acid and alkali), and waterproof performance.
