Atlas Fibre products

The FR-4 material from Atlas Fibre is a flame retardant glass epoxy laminate, distinguished for its mechanical strength and insulation resistance. Comprising woven fiberglass and a flame-retardant epoxy resin, FR-4 is expertly utilized as an insulator in both dry and humid conditions. Known for its stable mechanical and electrical performance, it serves various applications across industries. FR-4 stands out with its flame retardance, achieved through the inclusion of chemicals that mitigate fire spread. Specifically designed to meet MIL-I-24768/27 standards, FR-4 outperforms its predecessor, G-10, by offering superior resistance to flames. The fabrication process is akin to that of G-10, requiring standard cutting machines but with lower shearing strength and adjusted tool angles. Despite its durability, exposure to ultraviolet light can decrease its structural integrity outdoors, necessitating attention in those conditions. FR-4 is a versatile material available in sheets, rods, and tubes, widely used in aerospace, electric vehicles, and semiconductors.

FR5 is a fire-retardant glass epoxy material distinguished by its excellent thermal and electrical insulation properties. Comprised of a glass-fiber matrix and an epoxy resin, FR5 shares properties with the G11 and FR4 materials but stands out for its superior ability to resist high temperatures and fire. Its chemical resistance, high tensile strength, low moisture absorption, and high impact strength make it an ideal choice for demanding applications. Particularly valuable in high-temperature environments, FR5 ensures no melting and effectively prevents fire spread, which is why it is widely used in the automotive industry. Atlas Fibre's ability to customize FR5 materials in various forms, lengths, thicknesses, and diameters makes it possible to meet specific application needs with high precision and efficiency. With a focus on customer service, Atlas Fibre is committed to helping clients select and source the most cost-effective and practical material solutions available.
