①大多数塑料质轻,化学性稳定,Most of the plastic light weight,chemical stability,and will not rust
②耐冲击性好：Good impact resistance
③具有较好的透明性和耐磨耗性：Has good transparency and abrasion resistance
④绝缘性好,导热性低：Good insulation,low thermal conductivity
⑤一般成型性、着色性好,加工成本低：General molding,color is good,low processing costs
⑥大部分塑料耐热性差,热膨胀率大,易燃烧：Most of the poor heat-resistant plastics,thermal expansion rate,easy burning
⑦尺寸稳定性差,容易变形：Dimensional stability is poor,easily deformed
⑧多数塑料耐低温性差,低温下变脆：The majority of poor low-temperature-resistant plastic,low temperature embrittlement
⑨容易老化：Easy to aging
⑩某些塑料易溶于溶剂：Some plastics soluble in solvents.
