Trasy Enterprises make machines to do Hot melt adhesive coating on foam. It is a common technique used in various industries, such as packaging, automotive, and upholstery. It involves applying a hot melt adhesive to a foam surface to bond materials together, create a protective layer, or provide structural integrity.
Here’s how the process typically works:
Hot melt adhesives are solid at room temperature and are typically applied in molten form. The adhesive is heated in a special melter to a specific temperature, turning it into a liquid. Once the adhesive is melted, it is applied to the release liner through a slot die. After the adhesive is applied, it cools and solidifies, then it is laminated to foam where it is transferred to foam sheet. Depending on the adhesive used, the bond can provide flexibility, durability, or a variety of other properties.
Key Benefits:
Quick setting: The adhesive sets quickly as it cools, allowing for faster production cycles.
Versatility: Can bond to various types of foam (polyurethane, polyethylene, etc.) and other materials.
Durability: Once set, hot melt adhesives are often strong and durable, with good resistance to heat and moisture.
