In this article, we delve into the question: What Is Tie Layer Adhesive? We aim to answer it in simple terms, focusing on the real-life applications of tie layer adhesives. Stay with Aria Polymer in the following sections:
What Is Tie Layer Adhesive?
Tie Layer Adhesive (also known as Multilayer Adhesive), as the name suggests, is a type of adhesive, but its application sets it apart from regular adhesives. This adhesive is specifically used when a polymeric layer, such as polyethylene (PE), needs to be bonded to a non-polymeric layer, such as metal. In other words, when different materials need to be joined, like PE to steel, tie layer adhesive provides the necessary bonding strength and compatibility.
The image above shows a tie layer adhesive. This adhesive typically comes in granule form and is widely used, especially in pipe manufacturing.
A granule is a small polymeric particle. Polymer-based materials such as polypropylene, polyethylene, and polymer additives like masterbatches are mostly produced in the form of granules. Granules are melted during the production process to manufacture plastic products.
MultiLayer Adhesive Applications
Tie layer adhesive is primarily used in pipe manufacturing, where bonding multiple layers is necessary to form a multi-layered structure. For instance, in five-layer pipes, the inner and outer layers are typically made of polymer, while the middle layer is aluminum. Tie layer adhesive is used to bond these different materials together, ensuring structural integrity and performance.
Tie layer adhesive is also used in the manufacturing of corrugated and PEX/PERT pipes. Its application is not limited to pipes alone, it is also widely used in the production of packaging film and automotive spare parts.
Packaging films, despite their thin appearance, are composed of multiple layers. These layers are bonded together using tie layer adhesive.
Tie Layer Adhesive Quality
The quality of tie layer adhesive directly affects the lifespan of a pipe. Under the same conditions, a pipe using high-quality adhesive will last significantly longer than one using medium or low-quality adhesive, as the adhesive is responsible for bonding the pipe’s layers together. These layers often need to withstand high pressure, elevated temperatures, and even underground conditions, making the adhesive a crucial component.
The quality of an adhesive largely depends on the raw materials used in its production, but the application method and mixing proportions are also critically important.
