PBS Xinjiang Lanshan Tunhe TH803S
Xinjiang Blue Mountain Tunhe TH803S PBS (Polybutylene Succinate)
TH803S PBS is a bio‑based and biodegradable resin produced from renewable resources such as sugarcane and corn. It delivers mechanical properties comparable to PP and ABS, good heat resistance (heat‑deflection temperature close to 100 °C), excellent biodegradability and low environmental impact. It has obtained multiple international certifications for biodegradability and food‑contact safety including EU EN13432 and US BPI.
Main Applications
Food Packaging: Disposable tableware, cling film (compliant with FDA food‑contact requirements). Agricultural Products: Agricultural mulch films, seedling pots (controllable degradation under natural conditions). Medical Consumables: Medicine bottles, cotton‑swab sticks (low cytotoxicity).
