AVSS 80℃ Automotive Thin-Wall Low Voltage Wire Compound

The AVSS 80℃ Automotive Thin-Wall Low Voltage Wire Compound is a specialized polyvinyl chloride (PVC) based material formulated for the extrusion of ultra-thin primary insulation in automotive wire harnesses. Engineered to meet the JASO D611 and related international automotive standards, this compound provides the mechanical toughness required for thin-wall applications while maintaining electrical integrity at continuous operating temperatures up to 80℃. The material is designed for high-speed extrusion lines, offering a precise melt flow rate that ensures uniform wall thickness and concentricity, which are critical for the weight reduction and space-saving requirements of modern vehicle electrical systems. Its chemical composition is optimized to resist common automotive fluids, including engine oils, fuels, and brake fluids, ensuring long-term durability in under-dash and cabin environments.

AVSS 80℃ Automotive Thin-Wall Low Voltage Wire Compound

Core Advantages

  • Space and Weight Efficiency: Specifically developed for thin-wall (AVSS) insulation, allowing for smaller harness diameters and reduced vehicle weight compared to standard thick-wall cables.
  • Processing Stability: Optimized thermal stability and rheological properties minimize surface defects and die-drool during high-speed industrial extrusion.
  • Environmental Compliance: Formulated to meet RoHS and REACH regulations, ensuring the exclusion of heavy metals and restricted phthalates.
  • Color Consistency: Available as a pre-colored compound or a high-pigment masterbatch with dispersion characteristics that ensure opaque, vibrant identification colors even at minimal insulation thicknesses.

Product Characteristics

Technical Property Specification / Value
Operating Temperature -40℃ to 80℃

Application Scenarios

  • Automotive Signal Circuits: Primary insulation for low-voltage signal transmission in dashboards, door modules, and interior lighting.
  • Vehicle Control Units: Wiring for Electronic Control Units (ECUs) where compact harness routing is mandatory.
  • Audio and Infotainment Systems: Shielded and unshielded low-voltage cabling for in-vehicle entertainment networks.
  • Consumer Electronics: High-performance thin-wall wiring in applications requiring automotive-grade thermal and chemical resistance.

Storage and Processing Guidelines

  • Storage Conditions: Keep the compound in a cool, dry, and ventilated warehouse. Protect from direct sunlight and moisture. Seal opened bags immediately to prevent contamination.
  • Pre-Drying: While PVC compounds are generally non-hygroscopic, pre-drying at 60℃–70℃ for 2 hours is recommended if the material has been exposed to high humidity to ensure a bubble-free surface finish.
  • Extrusion Temperature Profile: Typical processing temperatures range from 150℃ to 180℃ across the extruder zones. Exact settings should be calibrated based on the specific L/D ratio of the screw and the line speed.
  • Safety Note: Avoid overheating the compound beyond 200℃ to prevent thermal decomposition and the release of hydrogen chloride (HCl) gas. Ensure the workspace is equipped with adequate localized exhaust ventilation.

Vehicle cable material:
PVC material for low-voltage wiring harnesses for environmentally friendly road vehicles

The environmentally friendly PVC material for low-voltage wiring harnesses for road vehicles is made of polyvinyl chloride resin as the base material, adding plasticizers, stabilizers, and other low-odor additives, and is prepared by mixing, plasticizing and granulating, which has aging resistance, low-temperature resistance, wear resistance, flame retardant and insulation properties. The product is suitable for high-speed extrusion, with a delicate surface, and meets environmental protection requirements such as ROHS2.0, REACH, NO-P, PAHS Class II, and BPA-free.
