Show Preview Xinfu
Show Preview Xinfu Zhejiang Hangzhou Xinfu Pharmaceutical Co., Ltd. is, among other things, a global leading manufacturer of vitamin B5. In addition XINFU specializes in the field of biochemicals, fine chemicals and Eco-Materials. Biocosafe is a type of biodegradable macromolecular polymer synthesized from diacid and diols by a direct process of condensation polymerization catalyzed by a highly effective non-toxic catalyzer that is developed by XINFU. It is certified compostable as to EN13432 and ASTM D6400. The Biocosafe resin series includes Biocosafe 1803 (PBSA), Biocosafe 1903 (PBS) and Biocosafe 2003 (PBAT), which can satisfy the different processing requirements of injection moulding, extrusion, blown film, fibre, bristle, straw and tube. Xinfu also have a research team to develop resin modification and product applications. XINFU is seeking opportunities to cooperate with different partner in order to develop biodegradable plastic market. www.xinfupharm.com N3K03 Fukan Plastics* Shanghai Fukun New Material Science & Technology Co. Ltd., presents AddiFlex oxo-biodegradable plastic additive as a viable, practical and easy to use solution for the present plastic littering situation in China. It was developed in Europe and the USA over the last 15 years. The picture demonstrates a real life test indicating oxidative degradation of an HDPE polymer carrier bag within 6 weeks in outdoor weather conditions similar to those in China, i.e. general weather conditions between 18°C and max 40°C, sunlight and rain. The results have been backed by a parallel test in Germany under weather conditions between 5°C and max 28°C, sunlight and rain. • The first stage of the degradation process leads to macromolecular chain breakdown due to the decomposition of peroxides which drives the auto-accelerating oxidation of the polymer, and it is this decomposition which is accelerated by the transition metal catalysis. Oxidation, technically known as degradation, as per ASTM D6954 • The second stage, known as the biodegradation stage, is when the material from stage one is metabolized by microorganisms resulting in biomass, water and carbon dioxide. www.fukan-cn.com N3S51 WinGram WinGram Industrial, a Hong Kong based company specialized in cellulose acetate (CA) material, started with traditional CA 15 years ago. WinGram is a major CA material supplier to most of the spectacle frame makers in China who produce European and US high quality branded frames. Two years ago they started developing biodegradable CA and successfully formulated their own 100% biodegradable polymer material which was recently certified to ISO14855. After the biodegradable material launch not only do the spectacle frame makers now ask for the material to build up their own Eco line, but also toy manufacturers started to test the material. An important advantage of working with WinGram CA material is that there is no need to modify or alter existing tooling or injection machines. The material passed comprehensive testing, such as impact, drop and hardening tests. Three grades are available: S70 is a 100% biodegradable CA. It is specially formulated for spectacle frame production and it is highly transparent if needed. It is suitable for both injection moulding and sheet extrusion. S72 is a 100% compostable CA. It is slightly yellowish but it is good for semi-transparent injection moulding and sheet extrusion processes for toys or other plastic products. S73W: This grade is a hybrid of CA and traditional plastic, or formulated as 100% compostable upon-request. Ready for coloring is an injection moulding grade material for toys or household products. The results exceeded the performance seen in controlled laboratory tests www.ecoplant.hk N3S39 30 bioplastics MAGAZINE [02/12] Vol. 7
Show Preview Hisun In 2012 Zhejiang Hisun Biomaterials Co. Ltd., heatresistant PLA resin received more and more attention from manufacturers of branded cutlery. Therefore, Hisun improved the existing type REVODE213 and developed a new heat-resistant modified PLA resin, Revode213S, which is perfectly suitable for durable heat-resistant tableware. Revode213S has excellent heat-resistance, higher safety, easier colour matching and brighter gloss, as well as better processing and mechanical properties. In terms of the cost, properties, food contact safety and many other characteristics, Revode213S performs better than high-end melamine products in the current market. In 2009, Hisun launched a cost-effective modified PLA resin, Revode213, with a heat-resistance of 90°C, which overcomes the low heat-resistance problems of traditional PLA and is better than starch-based products in processing and mechanical properties. All of these characteristics were quickly growing in popularity with the majority of tableware manufacturers. For better marketing, Hisun established a close cooperation with some professional green product manufacturers to focus on 100% biodegradable products such as disposable knives, forks and spoons. The product quickly won the international market’s recognition, a large number of orders from Europe and the United States pushed the manufacturers’ production capacity which was expanded several times in one year. At the same time Hisun also gained additional status through its heat-resistant PLA in the industrial field. www.plaweb.com N3L39 * As this preview is based upon an open invitation for editorial contributions from all exhibitors, it also contains information about companies presenting oxo-degradable products. However, we are still not convinced that these products will completely biodegrade. Until now, no independent scientific evidence has been presented to the editor. NatureWorks NatureWorks LLC is a company dedicated to meeting the world’s needs today without compromising the earth’s ability to meet the needs of tomorrow. NatureWorks LLC is the first commercial scale manufacturer and global supplier of polylactide biopolymer, which markets under the Ingeo brand name. Ingeo biopolymers are derived from 100% annually renewable resources with performance and economics that compete with oil-based plastics and fibres. By replacing petroleum with a renewable plant-based feedstock, NatureWorks production of Ingeo uses significantly less non-renewable energy, and generates significantly lower CO 2 emissions than all traditional petroleum-based polymers. The environmental credentials are backed by a rigorous, peer reviewed, published eco-profile. NatureWorks booth at Chinaplas 2012 will present a series of low-carbon-footprint products, including packaging, electronics, clothing, housewares, health and personal care, semi-durable, and the foodservice industry products which are made from Ingeo biopolymers. www.natureworksllc.com N3K31 Shenzhen Esun Founded in 2002, Shenzhen Esun Industrial Co.,Ltd not only inventively synthesize PLA in China, but also consider PLA modification as its overriding goal and obtain satisfactory achievement in PLA alloy. PLA alloy has excellent biocompatibility, good mechanical strength, elastic modulus, and thermoforming. Esun has launched two new PLA alloys: PLA/PBS alloy Esun 1323A and PLA/POM alloy Esun1604A. These two alloys contain a high amount of PLA. In line with pure PLA it can be processed easily on standard injection lines and converting equipment. Esun 1323A and Esun 1604A offer good toughness and impact resistance, shining surface and pigment ability, high mechanical strength, low shrinkage, can be used many applications. Esun PLA meets the requirements of EN13432 and ASTM D6400. www.brightcn.net N3M21 bioplastics MAGAZINE [02/12] Vol. 7 31
