CONTAVAL 2017

Description:
Contaval 2017 is a high-performance laminate based on epoxy resin and glass fabric, produced by a hot-pressing process. The material is known for its exceptional mechanical strength, dimensional stability, and excellent dielectric properties, even at higher temperatures and humidity. Thanks to the combination of superior mechanical and electrical characteristics, it is suitable for high-voltage applications, structural components, and insulation in the electrical industry.

Main Properties:

• High mechanical strength and rigidity

• Excellent resistance to temperature fluctuations

• High dielectric strength and low water absorption

• Dimensional stability even under high loads

• Self-extinguishing and high resistance to aging

• Excellent machinability (cutting, drilling, grinding, CNC)

Typical Applications:

• Structural components and insulators in electrical devices and switches

• High-voltage insulation, even under load

• Supporting parts and housings in electric motors, transformers, and generators

• Manufacture of structural components in railway, aerospace, and electronics industries

• Busbar supports, PCB holders, insulating barriers
