TECHNIPOL® PA 2188 is a co-polyamide based thermoplastic adhesive for automotive filter industry.
In air engine filter manufacturing it can be used for edge sealing, for reinforcing beads and for pre-filter element bonding. Beside this, in oil engine filter manufacturing it can be used for first/last pleat bonding and for ecological end caps molding.
It is characterized by a quick setting time, a good flexibility, a good wettability and a good chemical resistance.
TECHNIPOL® PA 2188 contains more than 80% of raw materials coming from renewable resources (not-edible).
