Polylactic Acid (PLA)

Introduction:

Polylactic Acid (PLA) is a thermoplastic polymer synthesized through the chemical polymerization of lactic acid, which is produced via biological fermentation. It possesses excellent biocompatibility and biodegradability. PLA is derived from lactic acid as its primary raw material, which is abundant and renewable. Its production process is environmentally friendly, and the final product can biodegrade, allowing it to integrate into the natural cycle, making it an ideal green polymer material.

Basic Properties:

PLA (H-[OCHCH₃CO]ₙ-OH) exhibits good thermal stability, with a processing temperature range of 170–230°C. It has strong solvent resistance and can be processed using various methods such as extrusion, spinning, biaxial stretching, and injection blow molding.

Applications:

Products made from PLA not only offer biodegradability but also feature excellent biocompatibility, gloss, transparency, texture, and heat resistance. It is widely used as a packaging material, fiber, and nonwoven fabric, with applications in clothing (underwear, outerwear), industrial sectors (construction, agriculture, forestry, and papermaking), and medical and healthcare fields.
