Application in Plastic & Rubber
Lactic acid is used in Plastic & Rubber where it is the primary component for manufacturing polylactic acid (PLA) plastics. Those bioplastics are an almost fossil-free substitute to classic polymeric elements based on petroleum. Also, it is plasticiser for rubber products in process which increase the elasticity and the resistance to heat. This is very useful in fabricating flexible but strong material that are more common to your everyday products, with a special attention to biodegradability.
