As a pillar of the national economy, the building materials industry relies heavily on metal sheets and profiles. However, high-temperature processing like cutting, welding, and thermoforming causes deformation, surface burns, and oxidation. Industry data shows average material loss from high-temperature processing reaches 15-20%, increasing costs and delaying projects.
Shenzhen Guangdayuan Film Co., Ltd.'s self-developed high-temperature resistant PET protective film provides a systematic solution. Using special polyester materials and high-performance coating technology, it passes tests: maintaining stability in -40 to 220°C for over 8 hours. During high-temperature metal cutting, its unique adhesive formula adheres tightly, forming a buffer heat-insulating layer. It reduces heat transfer by over 30%, controlling material deformation within 1%.
Its high-strength wear-resistant surface resists spark splashes and metal debris during processing. In a large steel structure factory project, using this film reduced surface scratches and dents by 90%, greatly improving material integrity.
With a complete R&D and production system, Guangdayuan has a full-process quality control system for raw materials, formula optimization, and process adjustment. Its R&D team adjusts film thickness, tack, and heat resistance based on metal thermal expansion coefficients and processing temperatures (for stainless steel, aluminum alloy, galvanized steel). Committed to "leading China's surface material environmental protection," its products pass SGS certification, free of phthalates and heavy metals. Widely used in bridges, high-rises, and factories, it has served over 500 key projects, boosting high-quality development of the building materials industry. #//www.petprotectivefilm.com/en/contact-us.html# #Protective film, PET protective film, high temperature resistant PET protective film, Guangda Yuan film, protective film manufacturer#
