Knowledge Sharing | Anti-Corrosion Heat Shrinkable Tape: Core Process, Application Scenarios and Construction Advantages FAQ
In pipeline anti-corrosion projects, choosing an anti-corrosion material that can withstand the test of the environment is the key to ensuring pipeline service life. To help customers better understand our product advantages and scope of application, we have compiled this FAQ to give you an in-depth look at the core process and outstanding performance of our products.
Q1: What are the core process and materials of your products?
A: Our products are mainly composed of a polyethylene (PE) substrate compounded with EVA hot melt adhesive.
Outer substrate: Made from high-quality polyethylene as the main raw material, compounded with light stabilizers, antioxidants, tackifying resins, and polar materials, giving the product outstanding aging resistance and mechanical protection.
Inner hot melt adhesive: The main raw material is high-performance EVA. For working conditions with special high- or low-temperature requirements, our technical team can formulate dedicated adhesive recipes tailored to your needs.
Q2: Compared with similar products on the market, where do your core quality advantages lie?
A: Our products stand in the market on "very good quality", with core construction advantages reflected in the following three aspects:
Strong adhesion and extremely high peel strength: The composite layer forms an extremely firm chemical and physical bond with the pipe surface, effectively resisting extreme soil stress and mechanical damage.
Perfect fit, no edge lifting: Thoroughly overcomes the industry pain point of edge lifting and opening commonly seen with inferior materials after installation, ensuring a long-lasting, dense anti-corrosion layer.
Excellent temperature adaptability: The product has an extremely high softening point and remains stable without flow at high temperatures; it also offers excellent low-temperature workability, maintaining outstanding flexibility and bonding even when installed in severe cold, without cracking.
Q3: In which pipeline projects are the products mainly applied?
A: Thanks to their excellent anti-corrosion and sealing performance, our heat shrinkable tapes/sleeves are widely used in three major scenarios: long-distance gas pipelines, thermal insulation pipelines, and water supply and drainage pipelines.
Q4: The substrate conditions of long-distance gas pipelines are usually complex. How is the bonding performance?
A: Extremely excellent. The bonding substrate of long-distance gas pipelines is the most complex, yet our high-adhesion hot melt adhesive can simultaneously adapt to various materials including the steel body, polyethylene (PE) outer layer, residual solvents from paint layers, and dedicated anti-corrosion primers, achieving all-round dense wrapping and preventing the intrusion of moisture and corrosive media.
Q5: What are the construction characteristics of thermal insulation pipelines and water supply/drainage pipelines?
A: In these scenarios, the bonding surface structure is relatively simple, requiring bonding mainly with the polyethylene (PE) outer layer of the pipe. Thanks to the excellent compatibility between the PE substrate and EVA hot melt adhesive and the extremely high peel strength, construction is fast and efficient, easily achieving a "seamless fusion" sealing effect between pipes.
💡 Conclusion:
Whether it is low-temperature construction in freezing regions or complex long-distance pipeline substrates, we are always committed to providing you with the most reliable pipeline anti-corrosion solutions that do not lift at the edges, are high-strength, and dependable.
