Optics, Eyewear

Frames and lenses for glasses, goggles, protective eyewear, and other optical applications require lightness and high impact resistance from transparent yet flexible polymers. Full portfolio of biobased options.

High Transparency

Transparency is important to allow for creative and beautiful design of glasses. Rilsan® Clear resins can even be more tranparent than glass.

Lightweight Resins

Compared to alternative transparent materials like PMMA, PC, and PEI, Rilsan® and Pebax® solutions are much lighter without sacrificing strength and toughness.

Biobased Solutions

The Rilsan® Clear and Pebax® Rnew® product ranges both have partially biobased grades, up to 65%.  This is acheived by putting oil from castor seeds through a series of chemical reactions before it is ultimately polymerized into high performance, long chain polyamide resins. These resins are also BPA and BPS free.
