XHP04

Our XHP04 double-cavity TPE sealing gasket reimagines standard solid single-channel weather strips, resolving core drawbacks of rigid PVC and ordinary solid rubber seals: poor shock absorption, rapid permanent deformation, and weak thermal isolation.

Enhanced Cushioning Sealing Core: Unlike solid seal profiles that flatten quickly under frame pressure, this dual hollow cavity layout creates built-in air buffer chambers. The dual hollow structure evenly disperses squeezing force from window and door frames, drastically cutting compression set and preserving a consistent tight seal year-round without sagging, gaps or air leakage.

Year-Round Outdoor Stable Performance: Crafted with upgraded modified TPE composite, this dual cavity seal overcomes common aging failures of cheap sealing products. It resists blistering, cracking and hardening under blazing UV sunlight, icy winter cold and long-term oxidation. Suitable for exterior windows, entry doors and balcony frames, it delivers steady sealing performance through all four seasons.

Zero-odor Safe Indoor Use: Traditional rubber gaskets emit irritating chemical fumes that linger in living spaces. Our XHP04 TPE formulation is fully non-toxic and odor-free, meeting eco-friendly household standards. Its smooth wear-proof outer layer slides effortlessly into standard frame grooves during installation, requiring no extra glue or complicated trimming for a snug, rattle-free fit.

Energy-Saving Multi-Layer Insulation: The double hollow air pockets act as natural thermal barriers to block indoor-outdoor heat exchange, lowering air conditioning and heating energy consumption. Meanwhile, the dense flexible TPE and dual cavity structure dampens external traffic noise, blocks fine dust and pollen, and eliminates cold drafts, creating quieter, cleaner and more temperature-stable indoor environments for homes and commercial premises alike.
