Biopolyesters
Biopolyester is produced from micro organisms produced from oil plants. Their degradation occurs in a short time under natural conditions in anaerobic, aerobic or compound. It has characteristics of softness and heat resistance similar to those of polyethylene and polypropylene.
Major Characteristics
– Good processability and high tear strength
– Good bubble stability.
– High tensile strength.
