Non-Bituminous Polymer Joint Sealing Tape is a high-performance sealing material specially developed for the overlap and butt joint sealing of polymer waterproof membranes such as HDPE, EVA, TPO, and PVC. It is composed of a polymer co-extruded film substrate and high-performance polymer pressure-sensitive adhesive, with a silicone release film on the surface.
Unlike traditional asphalt-based sealing tapes, this product contains no bitumen components and will not cause oil migration, contamination, or degradation of polymer waterproof membranes. The adhesive layer is highly compatible with polymer materials, forming a strong and durable bond while maintaining flexibility under temperature changes.
The tape provides excellent self-healing and sealing performance, automatically closing minor gaps and punctures to prevent water migration through membrane joints. With cold-applied installation, no heating or primer is required, making it a safe and efficient solution for underground waterproofing systems, tunnels, and high-performance polymer membrane applications.
Key Features & Benefits
When high polymer waterproof membranes require reliable joint sealing and long-term bonding performance, QINGYUAN Non-Asphalt Polymer Joint Tape provides a professional solution for overlap and connection waterproofing without damaging membrane performance.
Non-asphalt formulation prevents oil migration and avoids damage or contamination to HDPE, EVA, TPO, and PVC membranes.
Polymer-compatible adhesive layer creates strong bonding with high polymer membranes without peeling or separation.
Self-healing sealing performance automatically closes minor gaps and punctures to prevent water migration at joints.
Excellent temperature resistance maintains stable performance from -30℃ to 90℃ without cracking or flowing.
Strong resistance to acids, alkalis, and underground corrosion ensures long-term durability in harsh environments.
Cold-applied installation requires no heating, primer, or special equipment, improving construction safety and efficiency.
High adhesion performance creates permanent sealing at membrane overlaps, joints, and connection areas.
Compatible with HDPE, EVA, ECB, TPO, and PVC waterproof membranes for various waterproofing systems.
Ideal for underground structures, tunnels, roof systems, pipe details, and high polymer membrane joint reinforcement.

Standard Construction Process
Professional joint sealing methods ensure strong adhesion, reliable waterproof connections, and long-term protection for high polymer waterproof systems.
Joint Surface Preparation
Clean dust, sand, water stains, release agents, and other contaminants from the membrane joint area. Ensure the surface is clean and dry before application.
Tape Selection & Cutting
Select the appropriate tape width according to the membrane overlap requirements. Prepare sufficient bonding area on both sides of the joint.
Tape Positioning & Application
Remove the release film gradually and align the tape with the membrane joint. Apply evenly while pressing the tape onto the connection area.
Rolling & Air Removal
Use a rubber roller to press repeatedly from the center outward, removing trapped air and ensuring complete adhesive contact without bubbles.
Joint Reinforcement Treatment
Apply additional tape layers at important areas such as membrane ends, double-layer overlaps, corners, and construction joints for enhanced sealing.
Final Protection & Inspection
Allow sufficient bonding time before reinforcement installation or concrete pouring. Check all joints to ensure complete waterproof sealing.
