Modified plastics refer to plastics that have been improved or enhanced through physical, chemical, or mechanical processes to meet specific application requirements. These modifications improve the properties of the base plastics, making them suitable for a wide range of industries.
Modified plastic pellets are widely used in cable manufacturing, not only to enhance the overall performance of cables but also to meet specific requirements of various environments, such as high temperature resistance, flame retardancy, and low-smoke zero-halogen (LSZH) properties. By choosing the appropriate modified plastic pellets, manufacturers can effectively optimize the performance of cables.
Plastic pellets are essential components in cable manufacturing, primarily used to form the insulation, sheath, and other structural components of cables. Different types of modified plastic pellets, after modification, can meet diverse cable performance requirements, especially in terms of flexibility, heat resistance, flame retardancy, and electrical insulation. By selecting different modified plastic pellets, manufacturers can produce high-performance cables tailored to specific application scenarios.
LSZH (Low Smoke Zero Halogen): LSZH materials do not produce large amounts of harmful smoke and gases when burned, making them particularly suitable for environments with high safety and environmental requirements, such as rail transit, in-building cables, and public facilities. The low smoke and low toxicity properties of LSZH effectively protect people and the environment.
XLPE (Cross-linked Polyethylene): XLPE is a cross-linked polyethylene material with excellent heat resistance and electrical insulation properties. It is widely used in high-voltage cables and can significantly enhance the durability and insulation of cables, while maintaining stability even in high-temperature environments.
TPU (Thermoplastic Polyurethane): TPU has excellent wear resistance and mechanical strength, making it particularly suitable for cables in high-load environments. It significantly improves the wear resistance and aging resistance of cables, making it ideal for products exposed to outdoor environments for long periods, such as industrial robot cables and drag chain cables.
TPE (Thermoplastic Elastomer): TPE is a soft, highly flexible material known for its elasticity, flexibility, and tear resistance. It is widely used in cables that require frequent bending, such as connection wires for consumer electronics. TPE materials also provide a good tactile feel, making them very common in products like mobile phone charging cables and headphone wires.
PE (Polyethylene): PE has good electrical insulation and moisture resistance properties. It is a lightweight and cost-effective material commonly used as insulation in medium and low-voltage cables to ensure the safety and stability of cables.
Silicone: Silicone is a heat-resistant material that maintains stable performance even under extreme temperatures. Its flexibility and electrical insulation properties make it an ideal choice for high-temperature cables, as it performs exceptionally well in hot environments.
PVC (Polyvinyl Chloride): PVC is a versatile, cost-effective plastic that is commonly used in cable insulation and sheathing. It offers good chemical resistance, electrical insulation, and flame retardancy, making it a popular choice for low- and medium-voltage cables in various applications. It is also easy to process and has good mechanical properties.
EPDM (Ethylene Propylene Diene Monomer): EPDM is a highly durable material with excellent weather, ozone, and heat resistance. It is commonly used in cable insulation, especially for outdoor or exposed cables, as it can withstand harsh environmental conditions such as UV radiation, extreme temperatures, and chemical exposure. EPDM also provides good electrical insulation properties and is often used in automotive and industrial cables.

Modified plastic pellets can significantly enhance the performance of cables, thus improving the reliability of cables in various application environments.
Flexibility and Wear Resistance of TPE and TPU: In cables that need frequent bending, TPE’s flexibility and TPU’s wear resistance play a crucial role. These materials not only increase the cable’s tensile strength but also ensure the longevity of cables in complex motion states.
Heat Resistance and Insulation of XLPE: XLPE material retains its structural and insulating properties under high temperatures, making it an ideal insulating material for high-voltage cables. This material has strong resistance to electrical breakdown, reducing the possibility of insulation layer damage in high-voltage conditions.
Safety of LSZH Materials: Low-smoke zero-halogen materials do not release toxic gases or produce thick smoke during combustion, significantly reducing the risks posed by toxic gases in fire situations. LSZH materials are widely used in buildings, elevator shafts, subway stations, and other high-security areas.
Modified plastic pellets enhance the mechanical strength, durability, and electrical performance of cables, allowing them to perform efficiently in different scenarios. These materials further meet the growing performance, safety, and environmental requirements in the cable industry, driving the industry towards more efficient and eco-friendly development.
The outer sheath of a cable serves as an important protective layer with functions such as protection, abrasion resistance, waterproofing, and UV resistance. The selection of appropriate outer sheath materials in cable design can significantly enhance the service life of the cable.
PVC (Polyvinyl Chloride): PVC is a cost-effective material that is corrosion-resistant and easy to process. It is suitable for low-cost home cables and some industrial cables.
PE (Polyethylene): PE’s strength and durability make it an ideal choice for cable outer sheaths. It effectively prevents water penetration and is suitable for cables used in underground or damp environments.
LSZH: LSZH materials significantly reduce the emission of toxic gases and smoke during a fire, making them a key material for ensuring public safety. This material is widely used in building, elevator, and rail transit cables.
TPU: TPU’s excellent impact resistance and wear resistance enhance cable adaptability in harsh industrial environments.
The role of modified plastics in cable manufacturing is extremely important. Whether it's the flexibility and wear resistance of TPE and TPU, the high-temperature insulation properties of XLPE, or the low-smoke, low-toxicity advantages of LSZH, these materials play a key role in enhancing cable performance, ensuring safety, and meeting environmental requirements.
