Driven by global carbon neutrality goals, the new energy vehicle (NEV) industry is booming. Authority data shows NEV sales grew over 50% in the past year. However, battery safety has become a major concern. During frequent charging and discharging, batteries generate significant heat. In high temperatures, ordinary battery casings easily deform or crack, leading to serious safety risks.
With years of expertise in surface protection, Shenzhen Guangdayuan Film Co., Ltd. has launched a high-temperature resistant PET protective film— a reliable barrier for NEV battery safety. Using industry-leading production processes, this film maintains stable physical structure even at extreme 150°C, without deformation or melting. When applied to battery casings, it acts like a high-efficiency heat-insulating armor. It not only blocks external high temperatures from damaging the battery but also reduces heat damage from the battery to surrounding parts, fundamentally enhancing battery safety and stability.
Notably, the film has excellent chemical resistance. NEV battery electrolytes are highly corrosive, yet Guangdayuan's film resists various chemicals. Even with long-term contact with electrolytes, it won't corrode or dissolve, further extending battery life.
As a leading enterprise in China's surface protection adhesive products sector, Guangdayuan owns a 16,000-square-meter modern factory with internationally advanced production equipment. Through intelligent production management, it achieves large-scale, standardized production to meet the NEV industry's mass procurement needs. All products pass strict third-party certifications. Currently, Guangdayuan has established in-depth cooperation with major automakers, jointly upgrading NEV safety and contributing to the industry's healthy development. #//www.petprotectivefilm.com/en/contact-us.html# #Protective film, PET protective film, high temperature resistant PET protective film, Guangda Yuan film, protective film manufacturer#
