Dielectric Rubber
Excellent electrical insulation for high voltage and safety applications
View SpecificationsDielectric Rubber
Dielectric Rubber is an elastomeric material specially formulated to provide excellent electrical insulation properties, essential for high voltage applications, electrical safety, and protection against discharges.
With a minimum dielectric strength of 10kV/mm and excellent resistance to weather deterioration, this material is ideal for safety mats, protective equipment, and electrical components where insulation is critical.
Superior Electrical Properties
Dielectric Rubber stands out for its exceptional electrical and mechanical properties:
- High dielectric strength (10kV/mm minimum)
- Excellent acoustic insulation and vibration absorption
- Wide operating temperature range (-20°C to 145°C)
- Superior weather resistance and aging
- Excellent impact absorption and mechanical properties
These properties make it indispensable in electrical substations, high voltage work areas, and applications where electrical safety is a priority.
