TPE Expansion Joint Tape

Features & Benefits

• • Integrated Linear Waterproofing: the retractable lap design forms seamless linear connections across joints, realizing full-system waterproofing and eliminating hidden water leakage risks at splicing positions. It ensures the overall waterproof integrity of the entire engineering structure.
  • Permanent Low-Temperature Flexibility: the TPE raw material endows the tape with lasting softness and elasticity. It will not harden, crack or lose sealing performance even in low-temperature environments, suitable for use in cold regions all year round.
  • Excellent UV & Aging Resistance: formulated with anti-aging and UV-resistant components, the tape can withstand long-term outdoor sunlight exposure, rain and wind erosion. It resists aging, fading and performance degradation, extending the service life of the waterproof layer.
• • Acid & Alkali Resistant Polyester Fiber Base: the reinforced polyester fiber layer enhances tensile strength and structural stability. It features good acid and alkali resistance, adapting to complex underground, hydraulic and construction environments with corrosive media.
  • High Elasticity & Displacement Adaptability: superior stretch performance allows the tape to follow large-scale movement of expansion joints, avoiding tearing or detachment caused by structural displacement, vibration or temperature changes.
  • Customization Support: we provide customized colors to match different project design requirements, with standardized specifications and flexible order solutions to meet diverse engineering demands.
