Arkema Specialty Polyamides for Sight Glass and Pneumatic Lubricators


Published on

As the world’s largest producer of long-chain polyamides (nylons), Arkema's Specialty Polyamides business offers and the largest high-performance polyamide range in the industry, including 100% bio-sourced Rilsan® PA11 resins. The sight glass and pneumatic lubricator applications are a particular interest as we know that we can offer transparent nylons with excellent chemical resistance while improving processability and cost-effective production of the final parts.
