5V-90 90℃ Australian Standard PVC Sheath Compound

The 5V-90 PVC Sheath Compound is a specialized thermoplastic material engineered specifically to meet the rigorous requirements of the AS/NZS 3808 Australian and New Zealand standards. Formulated for power and telecommunication cable applications, this compound is rated for continuous operation at temperatures up to 90°C. It consists of high-molecular-weight PVC resin integrated with specialized plasticizers, heat stabilizers, and flame-retardant additives. The material is designed to provide mechanical protection for insulated cores, maintaining structural integrity under thermal stress and environmental exposure. Its chemical composition ensures UV stability and resistance to environmental stress cracking, making it suitable for the diverse climatic conditions found across the Oceania region. The compound is supplied in pelletized form, optimized for high-speed extrusion lines with consistent flow characteristics.

5V-90 90°C Australian Standard PVC Sheath Compound

Core Advantages

  • Standard Compliance: Fully compliant with AS/NZS 3808:2000 V-90 sheath requirements, ensuring regulatory acceptance for regional infrastructure projects.
  • Thermal Stability: Sustains mechanical properties during long-term exposure to 90°C operating environments without premature embrittlement.
  • Extrusion Efficiency: Balanced rheological properties allow for smooth surface finishes and consistent wall thickness at various extrusion speeds.
  • Flame Retardancy: Engineered to meet specific oxygen index requirements, reducing flame propagation in cable installations.

Technical Characteristics

Physical Property Test Method Technical Value
Operating Temperature AS/NZS 3808 90°C
Tensile Strength AS/NZS 1660.2.1 ≥ 12.5 MPa
Elongation at Break AS/NZS 1660.2.1 ≥ 150%
Hardness (Shore A) ASTM D2240 80 - 85
Aging (135°C × 168h) Variation rate Tensile/Elongation < ±20%

Application Scenarios

  • Building Wires: Outer sheathing for residential and commercial electrical wiring systems requiring 90°C thermal ratings.
  • Flexible Cords: Protection for heavy-duty flexible cables used in industrial machinery and portable tools.
  • Power Distribution: Low-voltage power cables utilized in underground ducts or exposed tray installations.
  • Control Cables: Sheathing for multi-core control and signal cables in automated industrial environments.

Storage and Processing Guidelines

  • Storage Conditions: Keep in a cool, dry, and ventilated warehouse. Avoid direct sunlight and contact with moisture or heat sources. Stack height should not exceed 10 bags to prevent compaction.
  • Pre-heating: While typically supplied ready-to-use, if the material is exposed to humidity, pre-drying at 70°C for 2 hours is recommended to ensure a pore-free extrusion finish.
  • Extrusion Temperature Profile: Recommended processing temperatures range from 150°C to 180°C across the barrel zones. Specific settings should be adjusted based on the L/D ratio of the extruder and line speed.
  • Safety Note: Ensure adequate ventilation in the extrusion area to manage vapors released during the heating process. Avoid heating the material above 200°C to prevent thermal decomposition.
