Thermoplastics for electrical applications

From circuit breakers to renewable energy products, polycarbonate helps the electrical industry bring its technologies to the market to meet the high demand for durable, rugged performance.

High heat resistance and good thermo conductivity material offer design freedom & high production efficiency in lighting applications
Materials with high heat resistance and good thermal conductivity offer design freedom and production efficiency in lighting applications.

Engineering resins play a fundamental role in the electrical industry – protecting products and people. Thermoplastics for electrical applications must offer reliable insulation properties, safe operation, high mechanical property profile and protection from electric shock. Polycarbonate, copolycarbonate and polycarbonate blends from Covestro provide manufacturers with many options for their specific electrical applications.

Makrolon® polycarbonate’s high mechanical strength, heat resistance (up to 145 ℃) and outstanding electrical insulation properties makes it the material of choice for electrical engineering, especially when transparency and flame retardance are required.

Apec® copolycarbonate is a popular choice for applications requiring high heat resistance (up to 220℃) and electrical insulation.

Bayblend® (PC+ABS; PC+ASA blend) resins offer good flow ability, good mechanical properties, with good flammability and electrical characteristics, making the material ideally suited for connectors, cable ducts and other electro-technology products.

Manufacturers often select Makroblend® (PC+PBT; PC+PET blend) resins for applications, including housing for electrical tools, requiring stringent heat deflection temperature, chemical resistance, high dimensional accuracy and stability levels.

Data on flame behavior and rheological, mechanical, thermal and electrical properties aids manufacturers with material selection. Results of ball indentation, glow wire flammability and tracking resistance tests help ensuring that the chosen materials meet the specific products requirements and mandatory standards.

Wherever reliable thermoplastics for lighting, sockets or other electrical applications are needed, polycarbonate materials provided by Covestro fulfill manufacturers’ needs.
