Biodegradable Resin PBAT/PBS by Xinjiang Blue Ridge Tunhe
As a subsidiary company of Xinjiang Blue Ridge Tunhe Chemical, Xinjiang Blue Ridge Tunhe Polyester Co., Ltd is an innovative company, relying on the advantages of Xinjiang’s local plentiful natural resources, boasting of the most advanced production facilities in the industry and concept of green development. The company is dedicated to producing biodegradable and compostable resin PBAT and PBS with current capacity 70000 mt per year (one of the biggest around world). Thanks to the cooperation with Tsinghua University to get cutting- edge continuous production technology and our 21 years of polymerization experience in polyester industry, the quality of our PBAT and PBS are widely recognized by customers around the world.
Tunhe’s PBAT and PBS are completely compostable according to various international standards and regulations like European standard EN 13432 and American Standard ASTM 6400, which will be eventually biodegraded to carbon dioxide, water and biomass when metabolized in the soil or compostable under standard conditions. Our resins are also certified by Ok Compost, BPI, ABAM, JBPA, FDA, EU Food Contact regulations, etc.
Compared with other biodegradable plastics, PBAT and PBS have excellent mechanical performance, almost same as PP and ABS, good heat resistance and outstanding processability allow it to be variously processed on conventional blown film plants, it is the best biodegradable plastic in terms of processability in current market and can be blended with a great quantity of calcium carbonate and starch etc. to produce cost effective products.
PBAT
Poly (butylene adipate-co-terephthalate)
Grade：TH801T
Molecular formula：H-(O-(CH2)4-O-CO-(CH2)4-CO-)n-（O-(CH2)4-O-CO-C6H4-CO-）m-H CAS NO：55231-08-8
Color：Natural white
Raw material：BDO (1,4-butanediol), PTA (terephthalic acid) Adipic Acid
Application：Film bags mulching films paper coating labels 3D printing other packaging materials
Technical Data：
Storage：
Temperatures during transportation and storage should not exceed 70 oC. Keep resin in dry and ventilated warehouse to prevent moisture. Avoid contacting with soil, water and sludge, and no exposure to direct sunlight and extreme temperature. The maximum shelf life is 2 years in ambient temperature of 23oC if the package has been tightly sealed.
Drying：
It is recommended to pre-dry the material prior to getting the best processing performance. If the moisture of the resin is less than 0.05% pre-drying may not be needed. Typical drying conditions：2 hours at 80oC (175oF).
