Paper, cotton, and glass cloth are combined with various resin systems and laminated under heat and pressure to produce materials with excellent mechanical and electrical properties.

During this process, the application of heat and pressure triggers a chemical polymerization reaction, transforming the layered structure into a solid, cohesive mass. This transformation is irreversible under normal conditions; once cured, the material cannot be re-softened by reheating—except under special circumstances.

This irreversible change in the resin’s structure creates an infusible, insoluble material, known as a thermosetting plastic.

Each grade offers a unique combination of mechanical, electrical, thermal, and chemical properties, making these materials highly versatile and ideal for a wide range of critical applications.
