PET protective films are commonly used in electronics, home appliances, automotive, and industrial applications to shield surfaces from damage. However, exposure to UV light and environmental factors over time can cause some films to turn yellow or become brittle, reducing their effectiveness.PET 保护膜通常用于电子产品、家用电器、汽车和工业应用，以保护表面免受损坏。然而，长期暴露在紫外线和环境因素下会导致一些薄膜变黄或变脆，从而降低其有效性。
Causes of Yellowing and Brittleness发黄和变脆的原因
UV Exposure: Prolonged exposure to sunlight and UV rays can break down the chemical structure of PET films, leading to yellowing. Guangda Yuan offers UV-resistant PET protective films that maintain long-lasting clarity and protect against discoloration.紫外线照射：长时间暴露在阳光和紫外线下会破坏 PET 薄膜的化学结构，导致其变黄。光大远提供抗紫外线的 PET 保护膜，可保持长久的清晰度并防止变色。
Heat and Oxidation: High temperatures can accelerate the aging process, causing the film to become brittle and lose flexibility. Our heat-resistant PET films are designed to withstand extreme conditions, ensuring durability in electronics and automotive applications.高温和氧化：高温会加速老化过程，导致薄膜变脆并失去柔韧性。我们的耐热 PET 薄膜可承受极端条件，确保电子和汽车应用中的耐用性。
Low-Quality Adhesives: Some lower-quality PET films use adhesives that are prone to degradation over time, affecting both the film’s performance and appearance. Guangda Yuan’s high-performance, stable adhesives ensure long-term protection without yellowing or brittleness.劣质粘合剂：一些劣质 PET 薄膜使用的粘合剂会随着时间的推移而容易降解，影响薄膜的性能和外观。光大远的高性能、稳定粘合剂可确保长期保护，不会变黄或变脆。
