Product Classification

High-molecular-weight polylactic acid (HM-PLA)

Categories：

New biological materials

Product Name: High Molecular Weight Polylactic Acid (HM-PLA) - Superior molecular architecture :D‑isomer content of only 0.7%(vs.1%in standard PLA)and an internal crosslinking degree as low as 0.03%(vs.0.3%)ensure a highly linear chain structure,imparting higher melt strength and processing stability. - Significantly lower melt flow rate :MFR at 190°C/2.16kg is just 0.6 g/10min(vs.5 g/10min for regular PLA),making it particularly suitable for extrusion sheet,film forming,and blow molding processes where melt shape retention is critical. - Enhanced mechanical properties :Key indicators such as impact strength and flexural strength are improved by approximately 10%over standard PLA;elongation at break rises from 3%to 5%,markedly boosting toughness and product durability. - Improved thermal stability :Melting point(177°C)and glass transition temperature(62°C)are both elevated,with a heat deflection temperature of 56°C,enabling broader application scenarios.

Product Details

Henan Huiyang Bio-New Materials Co.,Ltd. (hereinafter“Huiyang Bio”)is a state-controlled high-tech enterprise located in Hebi City,Henan Province,China.The company is a joint venture between Henan Investment Group,Henan Bio-industry Group,Hebi Investment Group,and the internationally renowned Mitsubishi Chemical Corporation(via its subsidiary),benefiting from strong provincial state-owned enterprise backing and global technical expertise.Huiyang Bio is a sister company of our firm, Henan New Tuoyang International Trade Co., Ltd., both being members of the same parent group.

Huiyang Bio focuses on the R&D and pilot-scale production of High Molecular Weight Polylactic Acid(HM-PLA) .Derived from renewable biomass such as corn and cassava,this material boasts low carbon emissions throughout its life cycle and is fully biodegradable,making it an ideal substitute for conventional petroleum-based plastics and a key driver for green and sustainable development.

Core Technical Advantages

Compared with commercially available low‑fluidity PLA,Huiyang Bio’s HM-PLA delivers comprehensive improvements in molecular structure and macroscopic performance:

- Superior molecular architecture :D‑isomer content of only 0.7%(vs.1%in standard PLA)and an internal crosslinking degree as low as 0.03%(vs.0.3%)ensure a highly linear chain structure,imparting higher melt strength and processing stability.

- Significantly lower melt flow rate :MFR at 190°C/2.16kg is just 0.6 g/10min(vs.5 g/10min for regular PLA),making it particularly suitable for extrusion sheet,film forming,and blow molding processes where melt shape retention is critical.

- Enhanced mechanical properties :Key indicators such as impact strength and flexural strength are improved by approximately 10%over standard PLA;elongation at break rises from 3%to 5%,markedly boosting toughness and product durability.

- Improved thermal stability :Melting point(177°C)and glass transition temperature(62°C)are both elevated,with a heat deflection temperature of 56°C,enabling broader application scenarios.

Wide-Ranging Applications

Thanks to its excellent biocompatibility,transparency,antibacterial properties,gloss,and gas barrier performance,HM-PLA finds extensive use in:

- Medical&Healthcare :Bone screws,medical stents,surgical sutures,drug delivery carriers

- Aesthetic Medicine :Cosmetic microspheres,nanofibers

- Food Packaging :Eco-friendly containers,fresh-keeping films,foaming materials

- Industrial&Consumer Goods :3D printing filaments,engineering plastics,textile fibers
