SAM Composites India Pvt. Ltd. is engaged in manufacturing rigid laminate sheets for a variety of applications. We are one of the best EPGC rigid laminated sheets manufacturers, catering to electrical engineering, electronics and mechanical engineering domains. EPGC stands for Epoxy Glass Cloth, a greatly advantageous composite offering the combined benefits of insulation, strength, thermal stability and anti-corrosion. Our expertise in composites over the past 3 decades drives us to innovate and serve specific applications in diverse fields. This can be assessed by a great range of EPGC sheets that we make. Our sheets are popular by the name ‘Tufflam’ in the industry.
Our EPGC laminated sheets are rigid due to the alkali-free glass cloth, which is a tough material and non-conductive. The epoxy resin is known for its excellent adhesive, water and chemical-resistant properties. Together, these form a rigid composite that can withstand various electrical, mechanical and thermal conditions. Being one of the top REGC rigid laminated sheets manufacturers, we ensure the fabrication process is completed with precision and the desired outcomes are achieved. The reinforcement and resin are composed and treated in an accurate quantity. The sheets are hot-pressed under high temperature and pressure to form a cohesive bond.
If you are looking for EPGC rigid laminated sheets suppliers, look no further than SAM Composites India Pvt. Ltd. We are a trusted partner of clients across the domains of high end electrical appliances as well as consumer electronics. In serving on a wide scale, we make sure none of the quality parameters are compromised.
