What is Non-woven Fabric Butyl Tape?
Non woven butyl tape is a high-performance sealing and bonding material that combines a high-purity butyl rubber sealing layer with a polyester/polypropylene non-woven fabric substrate. It is an environmentally friendly solvent-free product.
Structural composition:
• Butyl rubber sealing layer: low water vapor transmission rate, resistant to aging and oxidation, and maintains a soft and plastic state for a long time.
• Non woven substrate layer: provides structural reinforcement, tear resistance, can expel air during construction to avoid bubbles, and is suitable for various irregular and rough surfaces.
Performance advantages:
The advantage of non-woven butyl tape lies in its unique material properties:
• Good weather resistance: The adhesive is made of high-quality butyl rubber, which is permanently non curing and adapts to the movement and deformation of the structure. It can easily cope with the thermal expansion and contraction of building materials caused by seasonal changes.
• Good waterproof performance: Long term effective waterproof sealing, no water leakage, excellent waterproof performance.
• Multi layer waterproofing: The adhesive surface has excellent adhesion and is compatible with plastics, cement mortar, concrete, metal products, stone, etc. Its non-woven fabric surface has good plastering properties and good adhesion with cement mortar, firmly connecting each layer of waterproof layer.
• High and low temperature resistance: The colloid does not become brittle or crack at low temperatures of -40 ° C, and does not flow at high temperatures of 120 ° C.
