Polylactic acid or polylactide (PLA, Poly) is a biodegradable thermoplastic aliphatic polyester derived from renewable resources, such as corn starch (in the United States and Canada), tapioca roots, chips or starch (mostly in Asia), or sugarcane (in the rest of the world).eing able to degrade into innocuous lactic acid, PLA is used as medical implants in the form of anchors, screws, plates, pins, rods, and as a mesh. Depending on the exact type used, it breaks down inside the body within 6 months to 2 years.
PlatilonÂ®. PlatilonÂ® is the brand name for our thermoplastic films made from aromatic or aliphatic polyurethane. PlatilonÂ® transparent or colored blow-extruded films combine outstanding mechanical, chemical and thermal properties with suitability for thermoplastics processing technology.ynamic lordosis systems, special wound dressings, bullet-proof vests or opaque blinds â these are just a few of the virtually unlimited potential applications for PlatilonÂ® films. Numerous forms of processing are possible, taking in everything from lamination and welding to thermoforming and back-foaming.
