Temperature Changes are like the “Breathing Effect.” When the light is on, internal air heats up and expands, pushing out. When turned off at night, the temperature drops, creating a vacuum (negative pressure) that sucks in moist air or rainwater through the end caps or microscopic cracks in the PVC.
Our Insight: Think of PVC neon light as a “sprinter” holding an IP65 certificate. It looks great at the start, but its “breathing defense” isn’t built for a marathon. As the PVC becomes brittle from UV exposure, it can no longer resist the constant stress of expansion and contraction when temperature changes happened. In contrast, Silicone housing acts like a “marathon runner.” Its superior UV resistance and anti-cracking stability maintain a consistently dry internal environment for the LEDs, even under the daily pressure of thermal breathing.
If you are looking for long-term reliability and professional performance, explore our Silicone Advertising Neon Flex series. We provide precision-engineered solutions that eliminate “Dark Zones” and survive the “Marathon” of outdoor usage.
