Benefits of Polymer Pellets
Weather Resistance
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.
Outstanding Electrical Performance
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.
High temperature resistance、Low temperature resistance
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.
Abrasion resistance and Chemical Resistance
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.
Types of Polymer Pellets
LDPE (Low-Density Polyethylene)
LDPE is a plastic material that is very soft and flexible and is used in the manufacture of plastic bags, thin film, and containers. It even bears pressure, hence it is the most suitable for packaging.
High-Density Polyethylene (HDPE)
HDPE is more rigid and stronger than LDPE. HDPE is used extensively to manufacture products like milk jugs, detergent bottles, and lawn furniture. These plastic granules are tough in nature and possess excellent resistance to chemicals and impact.
LLDPE (Linear Low-Density Polyethylene)
Blending the rigidness of HDPE with the elasticity of LDPE, LLDPE offers a balance. It is universally used for films, stretch wraps, and plastic liners. Its flexibility allows a thinner material to be utilized without sacrificing strength.
PP (Polypropylene)
Polypropylene is a widely used plastic because of its heat resistance and strength. It is employed to make a broad range of products ranging from automobile parts, textiles, and medical equipment. Its strength and low water absorption make it fit for high-performance applications.
PVC (Polyvinyl Chloride)
PVC is a hard plastic and has widespread application in construction, such as in pipes, window frames, and vinyl siding. PVC is resistant to weather, durable, and an excellent electrical insulator. PVC can be made flexible as well when combined with plasticizers, and thus it is used in cables, flooring, etc.
PET (Polyethylene Terephthalate)
PET has the largest range of applications in making bottles and food packs, and in man-made fibers. It is clear and flexible with a good barrier for moisture and gas and hence can be a suitable option for packing.
Application of Polymer Pellets
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.
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.
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.
