Tie Layer Adhesive for Corrugated Pipe

In the modern infrastructure industry, the demand for spirally corrugated pipes is driven by the need for durability combined with flexibility. However, the core challenge in manufacturing these high-performance pipes lies in the structural bond between contrasting materials: the chemically inert polyethylene layers and the rigid metal reinforcement.
Our polymer adhesive compounds serve as the critical “tie layer,” acting as a molecular bridge between incompatible surfaces. By utilizing advanced functionalization technology, we have developed adhesives that chemically interact with both polar surfaces (metals like steel) and non-polar polymers (polyethylene). This dual-action bonding prevents delamination, ensuring that the pipe functions as a single, cohesive unit under pressure.

The longevity of a multilayer pipe depends entirely on the integrity of its intermediate layers. Our formulations are engineered to deliver:

Superior Interfacial Bonding: Maximizing peel strength to withstand mechanical stress and ground loads.
Long-Term Durability: Resisting environmental stress cracking and thermal fluctuations over the pipe’s service life.
Process Stability: Designed for consistent melt flow behavior, ensuring uniform coating during the spiral winding process.

We provide the chemical backbone that allows manufacturers to produce steel-reinforced polyethylene pipes of the highest caliber. Secure your infrastructure with adhesion technology designed for the future: Aria Adhesive 4100T319

Aria Adhesive 4100T319

Aria Adhesive 4100T319 is a premium maleic anhydride grafted PE (polyethylene) adhesive, engineered specifically to secure the integrity of spirally corrugated pipe production.
As a specialized tie layer adhesive, it addresses the critical failure points in multilayer structures. It serves as the vital bridge at the interface between inner/outer polyethylene layers and the intermediate steel reinforcement, ensuring a cohesive and durable pipe structure.
The bond between metal and plastic is naturally resistant to adhesion due to differing chemical polarities. Aria Adhesive 4100T319 acts as a high-performance compatibilizer, bridging the gap between these polar and non-polar materials.
By functioning as a chemical coupling agent, it eliminates the risk of delamination or structural separation. This results in a powerful, permanent bond between the polymer matrix and the metal profile, critical for the longevity of Steel Reinforced Corrugated Pipes (SRCP).

Key Advantages for Manufacturers include:

Optimized Peel Strength: The primary function of Aria Adhesive 4100T319 is to deliver high peel strength. By maximizing the interfacial adhesion between the steel ribs and the polymer body, it ensures the pipe maintains its structural integrity during handling, installation, and long-term service.
Enhanced Structural Stability: Beyond simple bonding, the adhesive contributes to the overall mechanical stability of the pipe. It allows the steel reinforcement to effectively bear loads while the polyethylene prevents corrosion, ensuring the “composite” nature of the pipe functions as intended.

Reliable Extrusion Processing: Formulated for thermal stability in demanding extrusion environments, this resin allows for smooth, continuous application. It maintains excellent flow properties without compromising line speed or finished product quality.

While primarily engineered as an extrusion adhesive for corrugated pipes, the unique chemical grafting of Aria Adhesive 4100T319 makes it the industry benchmark for any application requiring a robust bond between polyethylene and metal substrates.
