1. PVC material

Category 6, PVC, with foil shield, 4 pairs twisted, 26AWG

Definition: It is based on polyvinyl chloride as the basic resin, adding stabilizers, plasticizers, calcium carbonate and other inorganic fillers, additives and lubricants and other additives, through mixing, kneading and extrusion to prepare particles.

Advantages: It can be formulated to be used in various environments and applications. It has low cost, good flexibility, quite strong, and has the characteristics of fire/oil resistance.

Disadvantages: The low-end PVC material contains harmful substances, which may be unstable when used in special environments. The current PVC material has also been upgraded to enhance environmental protection elements and improve performance.

2. PE material

Super Category 6 shielded outdoor grade direct buried cable, PE sheath, 23AWG solid

Definition: Polyethylene material, this one is also very common. The linear molecular structure of polyethylene makes it very easy to deform at high temperatures. Therefore, in the PE application of the wire and cable industry, the polyethylene is often cross-linked to make the polyethylene into a network structure, making it strong at high temperatures. Anti-deformation ability.

Advantages: more environmentally friendly, generally such products have passed the EU ROHS environmental pollution test. Has excellent electrical insulation properties and good processing properties.

Disadvantages: general weather resistance, not suitable for high temperature environment.

Three, PUR material

Super Category 5, super flexible PUR sheath, shielded, 4 pairs of 26 AWG stranded wires

Definition: Polyurethane (PUR) is a polymer with repeating structural units of urethane segments made by the reaction of isocyanate and polyol.

Advantages: excellent oil resistance, good toughness, abrasion resistance, cold resistance (low temperature resistance), water resistance, aging resistance, acid and alkali resistance, weather resistance, long service life, UV resistance and many excellent functions, suitable for oil pollution, low temperature environments, etc. occasion.

Disadvantages: With many functions, the price will naturally be slightly higher. Compared with PVC materials, the cost will be much higher.

Four, TPE/TPR material

Super Category 5 SF/UTP cable, highly flexible CMX flame-retardant TPE sheath, 4 pairs of 24AWG stranded wires

Definition: TPE (Thermoplastic Elastomer) thermoplastic elastomer, sometimes called TPR (Thermoplastic Rubber), that is, thermoplastic rubber.

Advantages: It has good chemical resistance and oil resistance, and is very flexible, and it has better abrasion resistance.

Disadvantages: Not very sturdy, also not resistant to high temperatures, and usually cannot be used for a long time in an environment above 80°C.

Five, TPU material

Definition: Generally called polyurethane material, it is thermoplastic polyurethane elastomer rubber.

Advantages: Mainly divided into polyester type and polyether type, hardness range (60HA-85HD), abrasion resistance, oil resistance, transparency, and good elasticity. TPU not only has excellent high wear resistance, high tension, high tensile force, and strong It has the characteristics of toughness and aging resistance, and it is a mature environmental protection material.

Disadvantages: Slightly lacking in firmness and easy to deform.
