高分子新材料逐步代替钢铁、玻璃等传统材料,在汽车、电子电气等行业得到广泛应用。与此同时,生物基等可降解塑料及部分新型材料也开始投入应用,且发展潜力巨大。但在发展背后,却是行业内低端产品产能严重过剩,高端产品进口依存度居高不下,部分产品加工及合成技术尚不成熟。全国塑料加工工业协会公布的数据显示,我国有3 000多家塑料改性企业,但市场占有率却仅达30%。对此现
Polymer new materials and gradually replace steel, glass and other traditional materials, in the automotive, electrical and electronic industries are widely used. At the same time, bio-based biodegradable plastics and some new materials have also begun to put into use, and the great potential for development. However, behind the development, it is a serious overcapacity of low-end products in the industry and a high import dependence on high-end products. The processing and synthesis technologies of some products are not yet mature. Data released by the National Plastics Processing Industry Association show that there are over 3,000 plastic modified enterprises in our country, but the market share is only 30%. Right now
