Polyurethanes / Elastomers PPC Polyol from CO 2 Jiangsu Jinlong-CAS Chemical Co., Ltd., a Chinese company focusing on the reuse of carbon dioxide emissions to create new chemical materials, has developed a highly efficient catalytic system and innovative technology to produce biodegradable aliphatic polypropylene carbonate polyol (PPC polyol) by copolymerizing CO 2 with propylene oxide (PO). This kind of polyol, that has been proven to show a high reaction activity, may be widely used in the polyurethane (PU) industry. The company has developed the world’s first 10,000 tonnes per annum production line for PPC polyol. They own the intellectual property rights, including 15 Chinese patents concerning the catalyst preparation, polymerization technology, reaction (production) equipment etc. Polypropylene Carbonate Polyol Polypropylene carbonate polyol (PPC polyol) is a kind of colourless or yellowish viscous liquid with a rather complex molecular structure and a molecular weight ranging from 2000 to 5000 Daltons. It is made with more than 30% by wt CO 2 . PPC polyol shows a better hydrolysis resistance compared to common polyester polyols, as well as physical and mechanical properties superior to polyether polyols. PPC polyol could replace PTMEG (Polytetramethylene ether glycol) partially in superior artificial leather, that would exhibit good touch and feel properties and light weight quality – but also a certain toughness. The new polyol has also proven that it can be used to produce high adhesive strength coating materials (PU adhesive) and may be widely used in cast polyurethane (CPU) and thermoplastic polyurethane (TPU) elastomers. PPC Thermoplastic Polyurethane (PPC-TPU) PPC-TPU is a new kind of biodegradable polymer copolymerized from PPC polyol, BDO (1,4-butanediol) and MDI (Methylendiphenyldiisocyanat). It shows excellent biodegradability with the final level of biodegradation (ISO 14855) being higher than 90% after 130 days. The physical properties of PPC-TPU are similar to traditional TPU. It shows excellent impact strength, tear resistance and low temperature performance, as well as excellent adhesion etc. The product can be used for example for the production of industrial packaging materials or as an impact modifier additive for engineering plastics.

Not all chemicals are created equal TM By Jingdong Zong Jiangsu Jinlong-CAS chemical CO., LTD Taixing, Jiangsu, China Another advantageous property of PPC-TPU film is its relatively high barrier performance to O 2 and water vapour compared to other bioplastics. By blending with other biodegradable plastics such as PBS, PLA etc. PPC-TPU may improve the tear resistance of the compound. Jiangsu Jinlong-CAS successfully converted such blends into film that can be used for degradable mulch, shopping bags and waste bags, etc. Other compounds Jiangsu Jinlong-CAS is also cooperating with a partner to develop other new compound materials made with PBS, PLA, natural fibres (such as rice husk, plant straw ) and inorganic ingredients. By now they have successfully developed new heat resistance blended materials (up to 100°C). These materials can be used for the positive pressure and vacuum assisted thermoforming processes and for injection moulding. The main fields of application are food packaging and industrial packaging. www.zhongkejinlong.com.cn Application examples Myriant produces high performance, bio-based chemicals using renewable feedstocks that are not derived from food sources.
