SAM Composites India Pvt. Ltd. is one of the prestigious glass epoxy sheet manufacturers with more than 30 years of experience. Our sheets or fabric laminates are ISO and IEC certified by the latest guidelines. We are supporting the electrical and consumer electronics manufacturing industry, as well as aerospace, defence, and many other sectors. These are used in circuit boards, switchgears, motors, dry type transformers, machine parts, tools, and electrical structural components in marine, medical, and automotive industries. We make National Electrical Manufacturers Association (NEMA) grade fabric and matte laminates for these diverse applications. As we deal with clients from various fields, our team ensures to tailor the solutions to their requirements.
As the premium glass epoxy sheet manufacturers, we make sure the materials have the desired properties. These reinforced thermoset plastics have excellent thermal stability, chemical resistance, dielectric strength, flame resistance, and mechanical strength. These characteristics are essential for high voltage or long term insulation and protection of various electrical and electronic components. These resist melting and deformation due to high heat, thus maintaining the power and signal transmission. These are RoHS and Reach-certified products. We make them in various configurations such as G10, G11, FR-4, G7, G3, mid TG, high CTI, and low CTE. The FR-4 is used in areas where the risk of fire occurrence is high, as these have zero halogen and flame-retardant properties. On the other hand, G-10 is used in cryogenic applications like medical, fuel transport, and research & development works. These are tested by ASTM, NEMA and UL methods.
The combinations of glass substrate and resins are massive and sometimes infinite. Being one of the reliable glass epoxy sheet suppliers, our customization is flexible and precise. Low temperature and medium strength material for cryogenic applications, high tensile strength and dielectric strength for heavy duty electrical applications, low smoke emission for fire-prone areas are some of the varieties we provide.
If you are looking for the glass epoxy sheet manufacturers in India, SAM Composites India Pvt Ltd. should be at the top of your shortlist. Our sheets are designed to withstand tough environments in the manufacturing industries of heavy structural settings. We are certified by the latest regulations of relevant authorities like IEC, RoHS, ISO and NEMA. With our top grade materials, we have become a reliable partner of many reputed businesses over the years. Whether you belong to consumer electronics manufacturing or aerospace, we will serve you with the right solutions.
