Excellent Performance, Adapting to Various Environments
UL 83 PVC cable compound, with its versatile properties, is an ideal choice for building and general wiring applications:
Multiple Rated Temperatures and Environmental Adaptability: This PVC cable compound can meet the temperature requirements of different cable types, such as:
THHN (90°C Dry Locations): Provides excellent heat resistance in dry environments.
THWN (75°C Dry/Wet Locations): Suitable for both wet and dry environments, offering good water resistance.
THWN-2 (90°C Dry/Wet Locations): Achieves a higher temperature rating of 90°C in both dry and wet locations, providing enhanced performance.
This ensures that cables made from it operate safely and reliably in various indoor, outdoor, wet, or dry wiring environments.
Reliable Flame Retardancy: UL 83 compliant PVC cable compounds possess good flame-retardant properties. Wires and cables produced from them can effectively suppress flame spread in the event of a fire, enhancing the overall electrical safety level of buildings.
Good Electrical Insulation: The inherent dielectric properties of PVC material guarantee excellent electrical insulation performance for cables, effectively preventing short circuits and leakage, and ensuring the safety and stability of power transmission.
Excellent Mechanical Strength and Processability: While maintaining sufficient mechanical strength, this cable compound also offers good processing flexibility, facilitating efficient production for cable manufacturers and ultimately making cables easy for installers to install and route.
Wide Applications, Powering Urban and Rural Development

Processing and extrusion
Before extrusion, it is recommended to dry this model of product for about 2 hours at a drying temperature of 80 ℃. It is recommended to use a screw with a compression ratio of about 2.8-3.2 and good plasticization for processing. Due to the fact that the actual melting temperature is related to the length to diameter ratio, compression ratio, and screw structure of the screw, the appropriate extrusion temperature should be selected based on the specific situation of the extruder. At the same time, it is recommended to install copper wire preheaters in thin-walled products to ensure optimal product performance.
Storage
This product should be stored in a clean, dry, and ventilated warehouse and should not be damaged by abnormal conditions such as sun exposure, rain, or immersion in water. The storage temperature should not be lower than 0 ℃. The storage period of this product should not exceed 6 months from the date of production
