World’s First Plant-Based Bioplastic Eyeglasses by Teijin
Here is yet another development by Teijin Group Company with its first application for Eyeglasses. The new plant-based, heat-resistant bioplastic BIOFRONT is an advance polylactides with comparable heat resistance characteristics to oil-based plastics. BIOFRONT will be used for all plastic parts of eyeglasses frames including the temples, replacing the acetate which is commonly used for the plastic parts of eyeglasses. BIOFRONT unlike the acetate which cause bleaching in its contact with cosmetics or hire-styling products does not bleach. Furthermore, BIOFRONT has an antibacterial properties targeted to be used for eyeglass nose pads in avoiding skin rashes. BIOFRONT melting point is at 210 degrees Celsius which is 40 degrees higher than that of conventional polylactides and same is PBT a leading engineering plastic. Reduction of hydrolysis in developing BIOFRONT has been made possible through use of polymers and molecular-level control mechanisms technologies. The application of BIOFRONT is not limited to eyeglasses, its heat resistance properties can extend its application to automotive and electronics which requires high resistance to heat as well as humidity. The next step for Teijin in production of BIOFRONT is to enhance the environmentally friendliness of this plant-bases bioplastic by exploring possibilities for the chemical recycling of used BIOFRONT products. Teijin is planning to mass produce 5,000 tons of BIOFRONT in 2010 fiscal year, with expected sale of 50,000 to 100,000 pairs of BIOFRONT eyeglasses per year.
