Product Description
PVC HI-90 Sheathing
PVC HI-90 (Heat-Resistant 90°C) sheathing is a specialized thermoplastic compound designed for electrical cables requiring enhanced thermal stability. It retains the flexibility and ease of processing of standard PVC while offering superior performance in high-temperature environments. Key Features:
1. Temperature Resistance:
Continuous operating temperature: 90°C (up to 105°C for short-term exposure).
Improved heat deformation resistance compared to standard PVC 70°C.
2. Enhanced Thermal Aging Resistance:
Formulated with stabilizers to resist degradation under prolonged heat exposure.
3. Electrical Insulation:
Maintains stable dielectric properties at elevated temperatures.
4. Mechanical Durability:
Good abrasion, cut-through, and impact resistance.
Retains flexibility in cold conditions (typically down to -20°C).
5. Chemical & Environmental Resistance:
Resistant to oils, acids, alkalis, and moisture.
Optional UV stabilization for outdoor applications.
6. Flame Retardancy:
Complies with IEC 60332, UL 1581, and other flame-retardant standards.
7. Standards Compliance:
Meets UL 83 (Type THWN-2), CSA FT1, IEC 60227, and BS 6004.
Applications of PVC HI-90 Sheathing
1. Industrial Wiring:
Machinery, motors, and control panels in high-temperature environments.
Factory automation and process control systems.
2. Power Distribution:
Building wiring in areas with elevated ambient temperatures.
Feeder cables in power plants and substations.
3. Renewable Energy Systems:
Solar power cables (PV systems).
Wind turbine internal wiring.
4. Appliances & HVAC:
Heating equipment, boilers, and air-handling units.
Ovens, dryers, and other heat-producing appliances.
5. Automotive & Transportation:
Internal wiring in vehicles (non-critical high-temp zones).
Railway signaling and auxiliary power cables.
6. Commercial & Infrastructure:
Underground conduits (where moisture and heat resistance are needed).
Lighting circuits in high-temperature zones.
