高分子材料指的是分子量特别大的材料。常见的高分子材料可分成天然高分子材料和合成高分子材料。如淀粉和棉纤维是天然高分子材料。石油或天然气中经过一系列化学反应过程人工合成的高分子材料叫合成高分子材料,如工业上经常使用的尼龙、有机玻璃、ABS等。高分子材料可分成塑料、合成纤维、合成橡胶三大类。塑料按其热行为和成型工艺特点可分为热固性塑料和热塑性塑料两种。
Polymer materials refers to the material of particularly large molecular weight. Common polymer materials can be divided into natural polymer materials and synthetic polymer materials. Such as starch and cotton fiber is a natural polymer material. The synthetic polymer materials in petroleum or natural gas after a series of chemical reactions are called synthetic polymer materials, such as nylon, plexiglass and ABS which are often used in industry. Polymer materials can be divided into plastic, synthetic fiber, synthetic rubber three categories. Plastic according to its thermal behavior and molding process characteristics can be divided into two kinds of thermosetting plastics and thermoplastics.
