XHM313

The XHM313 coated weather strip is a kerf slot butt seal developed specifically for window systems that require reliable gap coverage, long-term resilience, and a clean installed appearance. Made with a high-performance polyurethane foam core and a durable PE outer coating, it delivers consistent sealing performance in demanding indoor and outdoor environments.

Optimized for window groove installation: XHM313 is designed for 5mm groove width and 2.7mm to 3.2mm groove depth, providing a secure slot-in fit for modern window profiles. Its 11.5mm compression capability suits installation spaces from 4mm to 6.5mm, making it a practical choice for window assemblies that need stable contact across wider gap variations without loose fitting or visible bulk.

Reliable sealing with low resistance: The PU foam core offers excellent elasticity and recovery, helping the strip maintain close and even contact over repeated use. With compression set ≤10%, it retains its sealing shape far better than many conventional materials, while compression force ≤10N supports a smoother closing feel. This combination helps improve window tightness without adding excessive operating resistance.

Built for weather exposure and long service life: The PE-coated surface provides strong resistance to wear, moisture, UV exposure, and aging, supporting effective sealing performance for more than 10 years. The material remains stable from -40℃ to 90℃ and withstands 500,000 opening and closing cycles without obvious deformation. With sound insulation of up to 45 dB, XHM313 offers dependable protection against wind, dust, water, and noise for high-performance window applications.
