1、Introduction 

       TZ812 is an opaque PLA resin modified with inorganic nucleating agents. It features fast forming speed, good dimensional stability,

       and is suitable for 3D products requiring high dimensional accuracy

2、 Physical & Mechanical Properties

3、Recommended Processing Conditions

General‑purpose screw: L/D ratio 24:1 to 30:1 Compression ratio 2.5:1 to 3:1 

4、Drying Process 

 TZ812 undergoes crystallization and drying before shipment (crystallinity > 30%, moisture < 400 ppm). PLA is hygroscopic. 

Re-drying is required after air exposure  more than 30 min or when recycled material is incorporated.

drying conditions are as follows:

5、Hazards & Handling

PLA exhibits few toxicity. Under normal use, accidental ingestion, eye or skin contact will not lead to adverse health effects. Nevertheless, appropriate care shall be taken during handling, storage, processing and disposal.

Good housekeeping is required for safe operation to minimize dust generation. Heat‑resistant gloves shall be worn for protection when contacting molten resin.

Steam and dust may form during handling and processing, which can irritate eyes and upper respiratory tract. An approved dust‑mask should be worn.

Adequate and comprehensive ventilation is required in the processing area.

6、 Waste Disposal

Do not discharge waste material into sewers or groundwater. For unused, uncontaminated PLA, recycling is the preferred option. 

Otherwise send to incinerators or other thermal‑treatment facilities. For used or contaminated PLA, the same disposal route applies, subject to prior risk assessment.

All disposal activities must comply with applicable local laws and regulations.
