FAQS on foam sealing strip

Q: What are the primary applications of silicone foam sealing strips?

A: Silicone foam sealing strips are ideal for high-temperature environments, such as oven doors or automotive engines. They offer excellent resistance to weathering, UV rays, and chemicals. Their flexibility ensures a tight seal against dust, moisture, and noise.

Q: How do I install a black PVC foam sealing strip effectively?

A: Clean the surface thoroughly and ensure it’s dry before applying. Peel off the adhesive backing and press the strip firmly into place. Avoid stretching the material to maintain its sealing integrity over time.

Q: What makes PU foam sealing strips suitable for outdoor use?

A: PU foam sealing strips resist water, mold, and temperature fluctuations, making them perfect for doors, windows, or roofing. Their closed-cell structure prevents moisture absorption. They also maintain elasticity in extreme climates.

Q: Can foam sealing strips be customized for irregular gaps?

A: Yes, materials like silicone, PVC, and PU foam can be trimmed or ordered in specific shapes. Their compressibility allows adaptation to uneven surfaces. Always measure the gap size to select the right density and thickness.

Q: How do I clean and maintain foam sealing strips?

A: Wipe with a mild soap solution and soft cloth to remove dirt. Avoid abrasive cleaners to prevent damage. Inspect periodically for wear and replace if compression or adhesion weakens.
