wire and cable
PVC is still used as the first polymer used in the wire and cable industry due to its advantages and benefits. The following are the advantages of PVC:
– Electrical properties and good insulation in a wide range of temperatures
– Inherent fire safety thanks to the low flammability of PVC
– Restrainability of flame emission and moderate heat emission
– Excellent durability and long-term use
– Easy processing
– Cost effectiveness
– Ability to recycle
– Resistance to hydrocarbons such as oil and diesel
– Good resistance to UV
In 2015, PVC as a polymer used in the cable industry, slightly higher than polyethylene, was able to occupy 50% of the market share.
Scope of application of PVC in the cable industry:
– Classic electric cables for power transmission in low and medium voltage for homes and offices
– Telephone cables
– TV / computer / HIFI coaxial cable
– Car cable
– Data transmission cables, LAN and IT
– Twin white nylon wire
– Ranjan wire cover (antenna, telecommunication, computer)
– Welding cable
– Spray cables
– Cable filler
Cable coating and insulation :
PVC is widely used for covering the cable in the structure of electric cables. In the 1950s, PVC gradually replaced rubber, which was used as a coating and insulation in household wires and cables. The cable made of affordable PVC has a very high durability and usually its lifespan reaches 25-30 years. Because its properties are easily modified, it is considered one of the most versatile thermoplastic materials. Although PVC is inherently rigid, it is easily modified with softeners, stabilizers, lubricants, and various other fillers. The cable with insulation or PVC sheath is flame retardant, which is important in most cases for electrical cables. PVC can withstand a wide range of chemicals including oil, acids and alkalis, the addition of various additives can increase its temperature range, typically from -40 to 105 degrees Celsius, as well as light resistance. Sun, reduce smoke emission and improve water resistance. Therefore, it is a suitable option for low and medium voltage cables. By producing a wide range of wire and cable industry compounds, Khoram Plastic Company has been able to make a great contribution to meet the needs of the country and also take a big step in the development of its export markets.
