What are the functions of PVC plastic film?

聚氯乙烯薄膜大致可分为两类，一类是增塑pvc薄膜，又称软质pvc薄膜，另一类是未增塑PVC薄膜，又称硬质PVC薄膜。聚氯乙烯塑料薄膜作用一般在电气方面用量最大，即电工胶粘带，根据其特性还可用于保护胶粘带、箱包粘胶带、标识胶粘带、广告贴、管路胶粘带等。在日常生活中也有广泛的应用，如，鞋业、玩具、雨衣、台布、雨伞、农用膜等。

PVC films can be roughly divided into two categories: plasticized PVC films, also known as soft PVC films, and unplasticized PVC films, also known as hard PVC films. Polyvinyl chloride plastic film is generally used in the largest amount in electrical aspects, namely electrical adhesive tape. According to its characteristics, it can also be used for protective adhesive tape, luggage adhesive tape, identification adhesive tape, advertising tape, pipeline adhesive tape, etc. It is also widely used in daily life, such as footwear, toys, raincoats, tablecloths, umbrellas, agricultural films, etc.

聚氯乙烯薄膜均不溶解于水、酒精、汽油，在醚、酮、氯代脂肪烃和芳烃中能溶胀或者溶解，常温下，耐浓盐酸、90％的硫酸、50％－60％的硝酸以及20％以下的烧碱溶液。

PVC film is insoluble in water, alcohol, gasoline, and can swell or dissolve in ethers, ketones, chlorinated fatty hydrocarbons, and aromatic hydrocarbons. It is resistant to concentrated hydrochloric acid, 90% sulfuric acid, 50-60% nitric acid, and less than 20% caustic soda solution at room temperature.
