Plastic is synthetic macromolecular compound, usually named plastic or resin. ;塑料件的应用领域（Plastic Application）;塑料分类 (Plastic Classification);合成树脂:是塑料中最主要的成分,是决定塑料类型、性能及使用的根本因素. Synthetic Resin: the main component in the plastic, the decisive factor of plastic types, performance and use 2. 填充剂:可以提高塑料的强度和耐热性能，比如木粉、纤维、硅藻土等 Filler: can improve the strength and thermal properties of plastics, for example, wood powder\fiber\diatomite ;3. 增塑剂: 可增加塑料的可塑性和柔软性，降低脆性，使塑料易于加工成型 Plasticizers: can increase the plastic plasticity and flexibility, reduce the brittleness, easy processing molding 4. 稳定剂: 防止合成树脂在加工和使用过程中受光和热的作用分解和破坏，延长 使用寿命。比如硬脂酸盐、环氧树脂。 Stabilizers: prevent synthetic resin’s decomposition and destruction by light and heat in the processing and use, to extend the service life. For example, stearic acid salt, epoxy resin. ;5. 色母粒: 使塑料具有各种鲜艳、美观的颜色 Color Master Batch: make plastic has all kinds of bright, beautiful colors ; ;聚乙烯（PE）Polyethylene;历史 History Born：1898 Mother：汉斯?冯?派克曼 Father：雷金纳德?吉布森 埃里克?福西特 发现背景：聚乙烯是在两次试验事故中被发现的，第一次是1898年派克曼在一次试验中发生事故，在爆炸现场发现白色蜡状物质。第二次是1933年3月雷金纳德?吉布森和埃里克?福西特研究高压对化学反应的影响时，在反应器里发现蜡状固体，后来确定是聚乙烯。 Background: polyethylene that was found in the two expe
