Overview
A soft, high-performance packing solution made from advanced expanded PTFE. Developed with innovative layering and high-temperature processing, it delivers exceptional flexibility, self-lubrication, and chemical resilience.
Key Benefits
-
Long Service Life – Maintains softness and adaptability over time, automatically filling potential leak paths. Highly resistant to corrosion and aging for reliable, durable use.
-
Easy Valve Operation – Exceptionally low friction and inherent self-lubrication enable smooth on-off action, even at ambient temperatures.
-
Clean, Pollution-Free Sealing – Pristine, pure-white PTFE ensures no contamination or shedding—ideal for pharmaceutical, food, and specialty chemical applications.
-
Inventory Efficiency – A few standard sizes can suit most valves, cutting down on inventory and costs. Even oversized valves can be packed tightly and molded for a precise seal.

Overview
A versatile, pure-white PTFE belt that brings together flexibility, resilience, creep resistance, and self-lubrication—making it an excellent sealing material across industries like chemicals, pharmaceuticals, food, power, metallurgy, and marine.
Ideal Uses
-
Sealing flanges on heat exchangers, reactors, towers—even those lined with enamel, glass, plastic, rubber, or graphite.
-
Connecting pipelines and fittings, especially with uneven surfaces, low bolt torque, or large diameters.
-
Ensuring contamination-free seals in critical applications, including aggressive or high-purity media.
Advantages
-
Superior Sealing Performance – Compresses to fill gaps and furrows; responds to pressure by expanding to seal more tightly.
-
Simple Installation – Cut to length, join ends, and shape to fit any flange. Adhesive backing holds it in place, and minimal bolt torque (≥ 50 kgf/cm²) is sufficient.
-
Exceptional Durability – Excellent corrosion and weather resistance enhanced by special treatments that improve creep resistance over time.
-
Clean & Non-Contaminating – Natural PTFE whiteness avoids shedding; corrosion resistance protects product purity.
-
Cost-Effective – Eliminates waste and the need for many custom gaskets. Compatible with damaged or aged surfaces, extending equipment life and reducing repairs.
Installation Tips
-
Ensure surfaces are clean and dry.
-
Select an appropriate width and thickness.
-
Remove liner and apply the tape around the flange, overlapping the ends by ~2–3 cm.
-
For face-flange applications, overlap ends; for recessed flanges, align parallel with the same overlap.
-
Tighten bolts evenly—the joint will compress to form a tight, leak-free seal.
