Product Description

Product Description

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.  

Advantages of PVC HI-90:
Higher heat resistance than standard PVC without sacrificing flexibility.  
Cost-effective compared to cross-linked (XLPE) or silicone alternatives.  
Wide industry acceptance with compliance to major standards.  

Limitations:
Requires UV stabilization for long-term outdoor exposure.
