Optics, Eyewear

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

SUSTAINABILITY AND PREMIUM PERFORMANCE

Arkema is the leader of high performance and biobased materials for optical applications, coming from castor oil.

Castor oil has a very favorable carbon footprint when it comes to making high performance polymers. The castor crop is inherently drought resistant, requiring very little irrigation or fertilization. It can grow in arid regions of the world where little else can sustainably be farmed.

High Performance Products for optical applications

Rilsan® Clear : For bio-based transparency

Arkema is the first manufacturer to provide high performance, bio-based transparent polyamides. Rilsan® Clear materials are ideally suited for optical solutions with high performance properties, offering lightweight, high transparency, flexibility for comfort and chemical resistance. Arkema offers two major references, especially developed for the injection of frames:

  • Rilsan® Clear G850 Rnew®: flagship of our range, this grade contains 45% bio-based carbon. This grade has been especially designed for injection molding applications and is ideally suited for high end eyewear frames.
  • Rilsan® Clear G820 Rnew®: With a high biobased carbon content of 65%, Rilsan® Clear G820 Rnew has an outstanding chemical resistance. Offering a high flowability, this material can be injected even for challenging designs and is excellent in overmolding, even over itself.

Pebax® Rnew® : Biobased elastomers

Arkema is the leader of high performance and bio-based elastomers, containing 30% to 97% biobased carbons coming from castor oil (based on ASTM D6866). The Pebax® Rnew® elastomers offer a wide range of flexibility, lightweight and has a high impact resistance. Moreover, it offers a good overmolding with Rilsan® Clear, offering a complete freedom for designing frames

Rilsan® PA11 for 3D Printing : 100% bio-based

Long-chain Polyamides are the reference materials in powder bed fusion processes like laser sintering (LS). This technology is used for manufacturing small series of personalized and uniquely desgined frames. Arkema offers polyamide 11 fine powders, providing flexibility, rigidity and impact resistance that other 3D printing plastics cannot obtain with 100% biobased carbon
