In the world of high-temperature applications, adhesive failure is the silent saboteur. A single debond in a car engine bay can lead to costly recalls. Guangdayuan disrupts this with a PU adhesive PET film that combines thermal stability with unwavering stickiness.
The Science of Thermal Adhesion
- Block Copolymer Design: Hard segments that reinforce at high temps, soft segments for flexibility.
- Hydrogen Bonding Network: Between PU and substrate for temperature-insensitive adhesion.
- Thermal Conductive Filler: 0.1% loading to dissipate heat and prevent hot spots.
Test data: At 100°C, Guangdayuan’s film maintains 85% peel force, vs. 15% for standard PU adhesives.
High-Temp Heroes
- Engine Components: Intake manifolds and exhaust covers.
- Industrial Ovens: Gasket seals and viewing window protection.
- Solar Panels: Backsheet adhesives in desert installations.
- Kitchen Appliances: Oven door films and cooktop protectors.
