PS型材——纳米塑木材料。
PS型材是继PVC发泡材料后新一代材料，完全替代木材。
不仅完全保留了传统木质装饰材料的性能，更以其环保、轻颖、高强度、防腐、防蛙、坚固耐用等无可以拟的优点。
上海天杰塑料制品有限公司近几年来一直从事PS型材项目的开发和研究，逐步形成了整套完整的新型材料系列。
目前，该新型材料已得到中国科学院上海科技查新咨询中心的认可，PS型材-纳米塑木材料被评为国内领先，国际先进的科技创新项目。
另外，和该项目相关的产品系列创新开发专利申请也已提交国家知识产权局，已提交专利申请的产品系列为：PS发泡型材、浴缸裙板和外墙护板。
随着时间的推移，更多的专利产品将被推向市场，走向全世界。
PS shaped bar is a kind of wood-like nanometer plastic material. The new material, which succeeds PVC, can completely  take the place of wood. It not  only pocesses the all charecters of triditionnal wood , it also has more advantages which wood is unable to poecsses, such as environmental protection, novelty, burliness ,antisepsis,mothproof,everlasting,and so on .Shanghai Tianjie Plastics Co.,Ltd .has been engaged in the development and research projects of the PS bar materials in recent years,and gradually formed a complete set of new material series. At present,the new material has been confirmed by the Chinese Academy of Sciences of the Novelty Search Center of Shanghi,the PS nano-wood materials is considered as the leading domestic,international advanced scientific and technological innovation projects. In addition,and the project related to the development of product line innovation patent applications have been submitted to the State Intellectual Property Office,Patent applications have been submitted for the product line:PS foam materials,tub skite panels and the external wall cladding panels.Over time,more proprietary products will be introduced to the market and to all over the world.
