Products Isosorbide
Isosorbide
Isosorbide is a biomass-based eco-friendly
material, and a carbon-neutral material
that can replace petrochemical materials.
Isosorbide is a fusion material made of food and chemical technology and
an Eco-friendly plastic raw material with 100% biomass content.
It is made by extracting starch from corn and then processing it into glucose and sorbitol.
Samyang Innochem produces and supplies Isosorbide first in Korea.
Applicable
Areas
Isosorbide, an eco-friendly plastic
raw material that is a high-profile material
across various industries.
Plastics, made of isosorbide extracted from vegetable raw materials, is not only eco-friendly but also has excellent transparency and a hard surface compared to conventional plastic.
As UV transmittance, heat resistance and chemical resistance are improved when ISB is used for durable plastics, it is in the spotlight in various industries, such as in exterior materials for electronic products such as TVs, various mobile devices, and liquid crystal films for smartphones, dashboards for automobiles, food containers, and eco-friendly building materials.
Polycarbonate, based on biomass
- Eco-friendly polycarbonate material with high bio-content and BPA free.
- Compared to conventional polycarbonate materials, improved optical properties
(low birefringence, high transmittance). - Excellent chemical, weather and scratch resistance and hardness.
- With excellent flow properties, easy to process.
