Techsil and Power Adhesives Develop High-performance Polypropylene-based Hot-melt Adhesive

Techsil and Power Adhesives have developed a solution to the industry wide issue of bonding polypropylene to itself in a fast and efficient way. Its new high performance polypropylene based hot melt adhesive bonds polypropylene quickly and efficiently.

This new hot melt adhesive does not require pre-treatment of the surfaces. It is applied hot from a standard 195°c gun and has a medium / long open time. Once the heat has dissipated, the surfaces will be bonded and high tear, peel and lap shear values are achievable. These values increase over time as the polypropylene elements of the hot melt cross link further with the substrates.

Polypropylene (PP) is a high tonnage polymer which is commonly used in many industrial sectors such as Textiles, Automotive, Packaging and a wide range of consumer goods. The low cost processability and chemical inertness of PP are the main reasons why it is used in a variety of applications and manufacturing processes. However, the chemical inertness of PP has reduced the use in some industrial applications because it is difficult to bond to itself and other substrates such as aluminium and steel. To overcome this problem, surface pre-treatment has been used such as chemical etching, flaming and corona and plasma treatments. Such processes and expensive, slow and can involve chemicals.

Techsil and Power Adhesives have developed this new grade of hot melt to meet the changing demands for increased productivity in industries such as automotive seating, moulded parts and other industries looking to replace ABS for the more cost effective polypropylene parts.
