Poly pellets are a common thermoplastic modified plastic raw material, typically processed into pellet form to facilitate handling and transportation. This material can soften and be molded when heated to a specific temperature and then cools to set into shape. As a thermoplastic material, poly pellets are widely used in producing cable sheaths, insulation layers, and other specialty cable compounds. Thanks to their diverse physical and chemical properties, poly pellets are ideal for maintaining excellent performance in various complex environments, making them a preferred choice in the wire and cable industry. Common types of poly pellets include low-smoke zero-halogen (LSZH) materials, cross-linked polyolefin (XLPO/XLPE), thermoplastic polyurethane (TPU), PVC, and thermoplastic elastomers (TPE/TPO/TPV).
Poly pellets offer several key characteristics that make them ideal for wire and cable applications:
Common poly pellets can maintain stability under extreme weather conditions, making them ideal for outdoor cable applications. This weather resistance is particularly advantageous for outdoor communication cables, photovoltaic cables, and other cables exposed to harsh environments for extended periods.
Depending on the application, poly pellets can be engineered to provide varying resistivity and dielectric strength, meeting insulation layer requirements. Their low conductivity and high insulation make them an excellent choice for cable insulation sheaths.
Common poly pellets can withstand a temperature range from -40°C to 125°C, maintaining excellent flexibility and mechanical strength even in extreme cold or high-temperature conditions. This meets the requirements for high-temperature or low-temperature cable materials used in electric vehicles and industrial control cables.
Poly pellets exhibit excellent abrasion resistance and chemical corrosion resistance, with strong tolerance to mineral oils, lubricants, and acidic and alkaline solutions. This characteristic makes them perform exceptionally well in cable applications in industries such as petroleum, chemical, and power.
Power Cables: Poly pellets are used in low and medium-voltage power cable sheaths and insulation layers due to their insulating properties and weather resistance, ensuring safe and reliable power transmission.
Communication Cables: Poly pellets are commonly used to manufacture the sheathing material of fiber optic and data transmission cables. Their weather resistance, abrasion resistance, and insulating properties effectively enhance the longevity and transmission quality of communication cables.
Automotive Cables: Automotive cables require high abrasion resistance and flexibility to adapt to the complex wiring environments in vehicles. Cable sheathing materials made from poly pellets provide excellent abrasion resistance and anti-aging performance, suitable for high-temperature cables in electric vehicles and wiring for other automotive electronic devices.
Industrial Cables: Poly pellets are widely used in industrial applications for manufacturing control cables, instrumentation cables, and other specialty cables’ insulation and sheath materials. Their chemical resistance makes them suitable for use in corrosive environments such as chemical plants and mines.

Halogen-free poly pellets can reduce smoke generation and harmful gas emissions during combustion. This feature is especially critical in public facilities such as subways, airports, and hospitals, where safety is paramount. Low-smoke HFFR poly pellet materials meet various flame-retardant standards for cables, providing enhanced safety and environmental protection for cable applications in these sensitive environments.
With exceptional physical performance and diverse chemical properties, poly pellets have become an indispensable material in the wire and cable field. Their outstanding weather resistance, abrasion resistance, chemical corrosion resistance, and adaptability to high and low temperatures enable them to meet the demands of applications ranging from communication and power to industrial and automotive sectors.
