Polypropylene (PP) Mesh Membrane Tape
YUXI’s polypropylene (PP) mesh membrane is a self-adhesive sealing tape designed for structure reinforcement, waterproofing and corrosion prevention in construction and maintenance applications.It can be used for the corrosion prevention of underground or overhead steel pipelines carrying oil, gas, and water, as well as waterproofing for roofs, tanks, and culverts.
Description
This cold applied tape consists of three integral layers: a potent adhesive layer formulated with a butyl rubber bituminous compound for strong bonding; a reinforced, tear-resistant mesh backing crafted from stabilized woven polypropylene fabric for durability; and a silicone-treated interleaf that serves to prevent the tape from sticking to itself during storage and handling, ensuring ease of use.
—— Features ——
Our polypropylene mesh membrane tape features high bond strength and excellent conformability with a consistent uniform thickness. It offers superior weather resistance and can be applied over a wide temperature range. With outstanding resistance to cathodic disbondment, it’s a versatile and reliable solution for diverse applications.
- High bond strength: adheres securely to surfaces, ensuring a robust and dependable connection.
- Excellent conformability and consistent uniform thickness: easily conforms to various shapes and maintains a uniform thickness, providing a snug fit and reliable coverage.
- High resistance to bad weather environment: offers superior resistance to adverse weather conditions, safeguarding against deterioration over time.
- Can be applied over a wide temperature range: can be applied over a broad temperature spectrum, ensuring flexibility and adaptability in various environments.
- Excellent resistance to cathodic disbandment: demonstrates exceptional resistance to cathodic disbondment, maintaining structural integrity and performance.
—— Practical Application ——
Our tape is widely used for multiple critical applications. It serves as an essential corrosion prevention material for underground or overhead steel pipelines transporting oil, gas, and water, ensuring their durability and safety. It effectively waterproofs roofs, tanks, and culverts, safeguarding structures from water damage and reducing maintenance costs.
