Read： 1025 Time：20months ago Source：Transform the World with Simplicity

PPR(Polypropylene Random Copolymer) is an amorphous copolymer polypropylene material, which is widely used in the field of chemical production raw materials. It has excellent properties and a wide range of uses, and has become an important material in many industries. This article will detail the nature and use of PPR.

1. PPR properties

1. Physical properties
PPR is a translucent, colorless, odorless, non-toxic plastic material with high density and hardness. It has good impact resistance, can maintain good toughness at low temperatures, and is not easy to embrittle. At the same time, PPR also has good heat resistance and can be used at high temperatures.

2. Chemical properties
PPR has good chemical corrosion resistance and can resist the corrosion of many acids, alkalis, salts and other chemicals. At the same time, PPR also has good oil resistance and can be used in oily environments.

3. processing properties
PPR has good processing properties, and can be made into various shapes of products by injection molding, extrusion, blow molding and other processing methods. At the same time, PPR also has good welding performance and can be connected by hot melt welding.

2. PPR uses

1. Piping system
PPR is widely used in piping systems, including cold water pipes, hot water pipes, heating pipes, air conditioning pipes, etc. Because PPR has good heat resistance, pressure resistance and corrosion resistance, it has become one of the preferred materials in the pipeline system.

2. Chemical equipment
PPR can be used to manufacture chemical equipment, such as storage tanks, reactors, agitators, etc. Because PPR has good chemical corrosion resistance and processing performance, it has become one of the commonly used materials in chemical equipment.

3. Automotive industry
PPR can be used in the manufacture of automotive industry, such as bumpers, dashboards, door panels, etc. Because PPR has good impact resistance and processing performance, it has become one of the important materials in the automotive industry.

4. home appliance
PPR can be used in the manufacture of home appliances, such as washing machines, refrigerators, air conditioners, etc. Because PPR has good heat resistance, pressure resistance and processing performance, it has become one of the commonly used materials in home appliances.

In conclusion, PPR, as an excellent raw material for chemical production, has a wide range of applications. In the future development, with the continuous progress of science and technology and the continuous expansion of application fields, PPR will be applied in more fields.
