Performance benefits: Redefining performance and stability in eyewear design

  1. Hardness Enhanced CA (HECA) properties: Frames made from BioAcetate S70 exhibit enhanced hardness without being brittle, allowing for more stable and thinner designs (as little as 1.5mm) and striking a perfect balance between flexibility and stability.
  2. Compatibility with all lens types: From AC to PC lenses, BioAcetate S70 proves versatile, offering compatibility with all lens materials.
  3. Protection against deformity: BioAcetate S70 significantly improves the 4-point balance of eyewear by mitigating the deformities inherent in many softer traditional acetates.
  4. Versatile frame options: The same material can be used for various applications. Whether in traditional injection frames, injection acetate frames or handmade acetate frames, BioAcetate S70 ensures flexibility in the application without compromising performance.
  5. Superior surface finishing: The material’s superior surface finishing not only simplifies and makes processing more efficient but also results in a better end product for consumers.
  6. Bio-friendly hardness: The incorporation of Hardness Enhanced CA (HECA) properties in all frames made from BioAcetate S70 ensures durability and stability without brittleness, for an enhanced final product.
