In the electronics industry, high temperatures are unavoidable during component production and soldering. Ordinary protective films often melt or deform under such conditions, damaging sensitive electronic parts. Shenzhen Guangdayuan Film Co., Ltd., a leader in the protective film sector with over 20 years of experience, has developed a high-temperature resistant PET protective film that perfectly solves this pain point.
During precision electronics manufacturing, soldering processes can reach temperatures above 180°C. Traditional films fail here—their adhesive layers melt, and the film itself curls. This not only fails to protect components but also risks contaminating precision circuits with residues. Guangdayuan's high-temperature resistant PET film uses imported optical-grade PET base material combined with self-developed nano-level high-temperature resistant coatings. Certified by authoritative institutions, it can work continuously for over 2 hours in 150-200°C environments, with a thermal shrinkage rate below 0.5%, completely eliminating deformation risks from high temperatures.
To optimize performance, Guangdayuan collaborates with Harbin Institute of Technology's materials science team. After over 3,000 simulation tests, they overcame the traditional challenge of balancing transparency and adhesion in high-temperature films. This film boasts a 92% light transmittance, allowing clear visibility of component details. It also uses gradient cross-linking technology to form stable chemical bonds between the adhesive layer and PET base, controlling peel force within 15-25g/25mm—ensuring strong adhesion without residual glue. Available in thicknesses from 0.03mm to 0.125mm and supporting customized cutting, it fits precisely with mobile phone chips, computer motherboards, and electronic sensors of various sizes.
In quality control, Guangdayuan has a full-process system covering raw material inspection, production monitoring, and finished product sampling. It strictly follows ISO9001 and ISO14001 standards, equipped with spectral analyzers and constant temperature-humidity test chambers. Each roll undergoes 28 quality checks. Trusted by over 300 electronics manufacturers like Huawei and Foxconn, the film has an annual output exceeding 50 million square meters, widely used in 5G communications, new energy vehicle electronics, and aerospace high-end manufacturing. #//www.petprotectivefilm.com/en/contact-us.html# #Protective film, PET protective film, high temperature resistant PET protective film, Guangda Yuan film, protective film manufacturer#
