Analyze the characteristics and application fields of PVC materials

   First, the characteristics of PVC material

   PVC material, polyvinyl chloride, is one of the world's largest production of plastic products. It has the characteristics of low price and wide application. PVC resin is white or light yellow powder, can not be used alone, must be modified. A variety of hard, soft and transparent products can be made by adding an appropriate amount of plasticizer to polyvinyl chloride resin. PVC material is widely used in building materials, packaging, medicine and other industries, especially suitable for ceiling and other decoration fields.

   Second, the difference between soft PVC and hard PVC

   Soft PVC material contains softener, easy to form addition, non-toxic and pollution-free, so it has great development and application value. The rigid PVC material is an amorphous thermoplastic resin made from vinyl chloride monomer through polymerization reaction, adding additives such as stabilizer, filler, lubricant and so on. Rigid PVC material does not contain softeners, so it is toxic. Therefore, the standard for judging whether PVC materials are toxic is whether they contain softeners.

   Third, the application field of PVC materials

   PVC material is widely used in building materials, packaging, medicine and other industries. In the field of building materials, PVC material is often used in the surface packaging of various panels, known as decorative film or adhesive film. In the field of packaging, PVC materials are often used to make plastic bags, plastic bottles and other packaging materials. In the field of medicine, PVC materials are often used to make infusion bags, infusion tubes and other medical devices.

   Fourth, the environmental advantages of PVC materials

   PVC manufacturing has a low consumption of energy, and at the later stage of use, PVC materials can be recycled and converted into other new products or incinerated to obtain energy. This feature makes PVC materials have advantages in environmental protection and meet the requirements of sustainable development.

   PVC material is a plastic that has a wide range of applications. Soft PVC material is non-toxic and pollution-free, suitable for various decoration fields. And hard PVC material contains softener, toxic. PVC manufacturing is low in energy consumption and has the advantage of being recyclable. Therefore, when choosing PVC materials, it is necessary to choose according to the specific use needs and environmental protection requirements.
