Product Description

Polylactic Acid Introduction

Polylactic acid, also known as polylactide, is a biodegradable polymer material polylactic acid prepared by further purification and polymerization with corn, potato and other starch based biomass or straw cellulose as raw materials. Polylactic acid (PLA) has excellent biodegradability. After being discarded, it can be completely degraded by microorganisms in the soil to produce CO₂ and H₂O without polluting the environment
lactic acid will be extracted, then PLA will be produced through a process of refining, dehydration polymerization, high temperature.

Application
As a biodegradable material, polylactic acid has the characteristics of environmental protection, non toxicity and degradability. It is the biodegradable material with the largest output, the widest application range, the highest cost performance and the closest to petroleum based polyester in the international market. Polylactic acid can be processed into films, sheets, staple fibers and filaments by injection molding and blistering. There is a large-scale demand in the fields of plastic industry, packaging industry, manufacturing industry and pharmaceutical industry. Polylactic acid is considered as the main material to replace petroleum based plastics (PE, PP, PVC, etc.) and petroleum based chemical fibers (PET, PTT, PBT, etc.) in the future.

(1) Green fiber made of polylactic acid can replace Petrochemical Fiber and be used in underwear, sports and leisure clothing, carpets, curtains, bedding, etc.
(2) Through extrusion, injection molding, blow molding and other processes, polylactic acid can be made into green plastics to replace petroleum plastics, such as household plastics (cups, plates, boxes, bottles, etc.), industrial plastics (car, ship, aircraft interior and parts, home appliance shell, etc.), film plastics (food packaging film bag, plastic bag, agricultural film, two-way tensile film, etc.), medical materials (surgical line, bone nail, etc.), 3D printing, etc;
(3) Polylactic acid polyols can be used to produce biological polyurethane, which can be used in many fields such as artificial leather, oil film, hard foam, soft foam and so on;
(4) The wood plastic materials produced by polylactic acid as adhesive do not contain bisphenol A and formaldehyde (urea formaldehyde resin and phenolic resin). They are widely used in indoor and outdoor decoration, furniture manufacturing, office furniture, etc.
