Epoxy glass cloth by SAM Composites India Pvt. Ltd. is widely used in making laminate sheets, tubes, cylinders and machined parts. Epoxy is a resin with excellent insulation and moisture resistance, while the woven glass cloth has great dimensional stability and strength. Together, these make a very durable composite. We are one of the top epoxy glass cloth manufacturers, serving the electronics, automotive, aerospace and other industries. Besides these heavy-duty applications, we serve the consumer electronics making industries as well. Our brand ‘Tufflam’ is famous among our wide customer base. They are essential for the safe passage of current, maintaining robust insulation, preventing the melting of insulating material, which exposes the conductor to dust and moisture, and providing sufficient mechanical support. We manufacture a wide variety of these sheets according to the most appropriate application.
Being one of the trusted epoxy glass cloth manufacturers in India, we assure our clients by testing our products on stringent parameters. We have received certifications from ISO, and have been tested by NEMA, ASTM, UL and IEC. Tests by these international agencies have proven our products to surpass the expected value regarding the mechanical, electrical and physical properties. These tests check the tensile strength, flexural strength, hardness, resilience, deformation, dielectric strength, short-time, permissivity, dissipation factor, breakdown voltage, thermal expansion, specific gravity, flammability, thermal conductivity and many other essential properties required for long-lasting protection of the respective parts.
As we are the leading epoxy glass cloth suppliers, we not only use these materials to make sheets but also in various forms. Copper-clad, moulded parts, machined parts, pultrusion structural components, tubes, and cylinders are some of the other forms apart from laminates. These are used in high mechanical, electronics, and electrical production units; cryogenic applications, and general power and distribution infrastructure. Besides being strong and resistant to corrosive elements and thermally stable, these are lightweight, with great abrasion resistance and modulus of elasticity.
