CO-POLYESTER
CO-PE

TECHNIPOL® 232 is an experimental co-polyester based thermoplastic adhesive designed for the production of air and oil filters in the automotive industry.

TECHNIPOL® 232 is an innovative development of TECHNIPOL® 32 which, maintaining the performances of TECHNIPOL® 32, achieves the double goal of a raw material cost reduction combined with a significant progress towards the circular economy model.

50% of monomers used in the synthesis of TECHNIPOL® 232 comes either from renewable sources (derivates of not edible vegetable oils) either from the selection and the treatment of post-consumer wastes. It is characterised by good chemical and thermal resistance and a high flexibility, that assures the integrity of the filter during all production steps.
