CROWN New Materials EPT Tapes — Providing Reliable Solutions for Automotive High-Temperature “Bake” Tests

In high-temperature conditions, vehicles left under prolonged sun exposure can reach temperatures above 60 °C, posing severe “bake” challenges to automotive safety and longevity. For automotive adhesive materials, many tapes face performance degradation under heat, including reduced adhesion and thermal expansion issues. As a solutions provider with over twenty years of experience in advanced adhesive materials, CROWN New Materials offers EPT tapes featuring high bonding strength, excellent heat and weather resistance, and strong sealing and waterproof performance. With a variety of thickness options, these tapes are widely applicable for bonding automotive exterior and interior components, as well as in new energy battery assembly.

For bonding exterior and interior automotive components, the superior performance of adhesive materials not only helps vehicles withstand high-temperature challenges and extend service life but also supports the industry’s move toward safe, reliable lightweight designs. CROWN New Materials’ EPT tapes combine specially formulated acrylic adhesives with acrylic foam, offering excellent conformability to compensate for thermal expansion and contraction of bonded parts. Additionally, they provide sealing, waterproofing, and vibration-damping functions, enabling vehicles to handle complex environmental conditions throughout their lifecycle.

Moreover, CROWN’s EPT tapes feature outstanding initial tack and die-cutting performance, simplifying the application process. They can be effectively applied to a wide range of automotive parts, including body trim, roof rails, seals, bumper guards, shark fins, wheel arches, automotive radar units, side mirrors, nameplates, air vents, seat cushions, headliners, and ETC boxes, achieving strong structural bonding. This versatility makes them particularly valuable for supporting automotive lightweighting initiatives.

In addition to bonding automotive exterior and interior components, CROWN New Materials’ EPT tapes are also used for inter-cell bonding in new energy vehicle batteries. Inter-cell bonding places higher demands on the overall performance of the tape. CROWN’s EPT tapes offer strong adhesion to ensure secure bonding between battery cells. They also provide excellent heat and aging resistance, delivering reliable protection for the safe and long-lasting operation of new energy vehicle batteries.

Furthermore, EPT tapes feature high initial tack, requiring no curing time, allowing for rapid forming and ensuring stable automated assembly between cells, which significantly improves installation success rates. Beyond batteries, the superior performance of EPT tapes also provides robust support for bonding glass covers on charging stations.

With over twenty years of industry expertise and technological experience, CROWN New Materials not only provides customized solutions, high-quality products, and rigorous experimental data but also assembles professional project teams to ensure smooth project delivery. Currently, CROWN’s EPT tapes have been successfully applied by multiple automotive brands, earning recognition and praise from clients. Looking ahead, CROWN New Materials will continue to innovate and evolve, delivering superior products and more efficient services to support the automotive industry in achieving high-quality development.
