Biodegradable plastics are plastics that are degraded by environmental microbes after disposal and eventually completely converted into mineralized inorganic salts of carbon dioxide, water and the elements they contain. From raw materials, mainly include: polycaprolactone (PCL), polybutylene succinate (PBS), polylactic acid (PLA), polyhydroxyalkanoate (PHA), etc., the most well-known biodegradable plastics. It is polylactic acid.
Polylactic acid (PLA for short), melting point of about 160 ° C, density of 1.24g / cm3, PLA monofilament produced by Xindike, wire diameter range of 0.07 ~ 3.0mm, environmentally friendly non-toxic, superior degradability.
PLA monofilaments are commonly used in high-grade toothbrush filaments, dental floss, surgical sutures, tea bags, 3D printing, and the like.
