Sustainability
Energy consumption patterns are changing towards sustainability and efficiency. We have witnessed an energy transition from fossil fuels to renewable energy sources like wind and solar, which help to reduce greenhouse gas emissions.

Supporting the energy transition across the entire power network

Powering every stage of the electricity network: Generation, transmission and distribution

Renewable energy grid with wind turbines, solar panels, hydropower, power lines and a residential building.
Energy storage systems
Custom silicone gaskets, hoses, thermal interface materials, and molded parts engineered for effective sealing, insulation, and fire safety in battery packs and BESS infrastructure.
Hydropower facilities
Reliable silicone profiles, gaskets, hoses, and molded components engineered for sealing, insulation, and vibration damping across hydropower turbines, generators, and electrical infrastructure.
Solar parks
Advanced silicone components—including junction box seals, grommets, and protective hoses—designed for maximum weatherproofing and durability in harsh solar farm environments.
Wind power
High-performance silicone and rubber solutions for onshore and offshore wind turbines. We deliver reliable sealing profiles, molded parts, hoses, gaskets, and vibration-damping components engineered for extreme environments.
High-voltage substations
Advanced silicone solutions for high-voltage substations. We engineer durable profiles, gaskets, insulating covers, and molded parts built to ensure long-term protection across critical grid infrastructure.
Insulators and bushings
Engineered silicone solutions for insulators and bushings. We supply heavy-duty housings, sheds, insulating covers, and weather-resistant seals designed for superior electrical insulation and long-term protection across transmission networks.
Cable accessories
Engineered silicone solutions for cable accessories and connections. We supply stress-control components, cable seals, insulating sleeves, grommets, and heat-shrink products designed for maximum environmental protection in medium- and high-voltage cable systems.
Silicone solutions for distribution substations
Reliable sealing, insulation, and cable protection for medium- and high-voltage substations. Our silicone profiles, gaskets, and molded parts deliver superior environmental resistance across distribution infrastructure.
Cable connections
Engineered silicone solutions for cable accessories and connections. We supply stress-control components, cable seals, insulating sleeves, grommets, and heat-shrink products designed for maximum environmental protection in medium- and high-voltage cable systems.
Electrical network components
High-performance silicone and rubber solutions for electrical network components. We supply durable seals, custom profiles, insulating boots, and molded parts engineered to ensure environmental sealing, dielectric strength, and long-term reliability across switchgear, circuit breakers, and distribution hardware.
