Show Review 封 面 故
Show Review 封 面 故 事 CHINAPLAS 2015 Review CHINAPLAS 2015, held from 20-23 May 2015 in Guangzhou, has again set new records with unprecedented scale, with a gross exhibition area exceeding 240,000 m² and over 3,200 exhibitors from 40 countries and regions. After our show preview in the last issue, our reporters did not report about significant breakthrough developemnts in the field of bioplastics at this year’s Chinaplas. Thus we just present a few news from the Bioplastics Zone, that comprised again a total of 28 companies plus another 23 companies showcasing bioplastics products or services in other halls. Guangzhou Bio-plus Guangzhou Bio-plus Materials Technology Ltd (Guangzhou, China) is a high-tech company focusing on modification of bio-based and biodegradable materials. Their talented R&D team cooperates with Scientific Academia of China. Guangzhou Bio-plus successfully improved PLA in heat-resistance, impact strength and the ability to expand, which significantly widens the field of applications for PLA. The most challenging topic in PLA modification is to improve its foam ability. Recently Bioplus succeeded in developing a modified PLA for extruded foam sheet with butane or CO 2 , and the material is being used commercially now. Its expansion rate can be controlled from factor 3 to 20, and the structure of the foam can be open-cell or closed-cell. PLA foam sheet can be used in packaging material, disposable food boxes, trays, Hamburger boxes, coffee cups, etc. It is the best option to substitute polystyrene foam and paper products in above fields. It has been a challenging task, to foam PLA in the extrusion process over the past years. A lot of institutes and companies studied this topic for many years, without significantly overcoming the lab-scale. Bio-plus however, has now succeeded PLA foam sheet with butane or CO 2 in industrial production line continuously and stably. This is a milestone that PLA foam material can be promoted in scale. In one word, Bio-plus’s success in PLA foam is revolutionary, and it will push the bio-plastics industry go forward quickly. http://www.bio-plus.cn/en/ CJ Cheiljedang CJ Cheiljedang (CJ) from Seoul, South Korea, one of the largest producers of amino acids, has developed renewable chemicals for Nylons, Polyurethanes, and Resins. CJ introduced biobased diamines – Butanediamine (BDA) and pentanediamine (PDA) - which can be used for Nylon and Polyurethane. BDA is a raw material for Polyamide 4X engineering plastics. PDA is for Polyamide 5X, high functional fiber, and PDI (pentamethylene diisocyanate), a raw material of urethane coating. CJ also made a great advancement in D-Lactic acid. PLA is a biodegradable polymer from renewable resources with about 200,000 tonnes market volume. PLAs made with D-LA (e.g. stereocomplex-PLA) have better heat resistance and mechanical properties than conventional PLA. Thus, they are more broadly applicable. Lignolic phenol is studied as bio-friendly chemical, but technological barrier limits its applicability. Innovative technology enables CJ to produce cost-efficient lignolic phenol, the preceding material of phenolic resins used in various industrial products. http://www.cj.co.kr/cj-en bioplastics MAGAZINE bioplastics MAGAZINE for the first time introduced a special Chinese language version of the magazine (16 pages “Best of 2014”). It was printed in 1000 copies and distributed at Chinaplas in addition to the 1000 copies of the regular, international issue. 山 西 金 晖 集 团 2015 年 5 月 A pdf-version of the complete Chinese issue can be read online at www.issuu.com/bioplastics or bit.ly/1AxH9BF www.bioplasticsMAGAZINE.COM 生 物 塑 料 杂 志 中 文 专 刊 26 bioplastics MAGAZINE [03/15] Vol. 10
