Filter Systems (Air / Oil / Fuel )
PU adhesives and foams ensure strong bonding and long-lasting sealing performance.
Additional Information
Polyurethane is widely used as the end-cap material in automotive air filters due to:
-
High mechanical strength for holding pleated media together
-
Excellent adhesion to paper, nonwoven, and synthetic filter media
-
Vibration and impact resistance during engine operation
-
Thermal stability up to 120–140°C
-
No shrinkage or deformation after curing, ensuring a perfect seal
PU ensures that dust, sand, and airborne particles do not bypass the filter, protecting engine components and maintaining air–fuel efficiency.
