PP plastic is a common plastic in our lives, the English full name is Polypropylene, referred to as PP. It has excellent physical properties, chemical stability and thermal stability, and is widely used in various fields, such as aerospace, automotive industry, electronic appliances, building materials and daily necessities. This article will introduce the concept, advantages and applications of PP plastics.

1. PP plastic concept

PP plastic is a polyolefin plastic, is a saturated hydrocarbon polymer. It belongs to the same class of plastics as polyethylene (PE), polypropylene (PP), polybutadiene (PBD), etc. PP plastic has the advantages of low viscosity, low density, good crystallinity, high transparency and good mechanical properties. It is an excellent engineering plastic. In addition, it is an environmentally friendly plastic that can be recycled and meets environmental standards. The advantages of

2. PP plastic

1. Good physical properties. PP plastic has high hardness, strength and wear resistance, and is not easy to deform, good durability.

2. excellent chemical stability. PP plastics are stable in strong acids, alkalis and organic solvents.

3. Good thermal stability. PP plastic can withstand high temperatures and maintain good mechanical properties, and can be used in a wide temperature range of -20 ℃ ~ 120 ℃.

4. Environmentally friendly plastics. PP plastic can be recycled, will not cause pollution to the environment, in line with environmental standards.

5 low production costs. Compared with other plastics, the production cost of PP plastics is lower, thereby reducing production costs and improving economic benefits.

3. PP plastic application

1. daily necessities field. PP plastics are widely used in various daily necessities, such as water cups, beverage bottles, hand sanitizer bottles, etc. The bottle made of PP plastic has a beautiful appearance and can be processed into various shapes with good sealing and durability.

2. Automotive industry. PP plastic has high heat resistance and high impact resistance, so it is widely used in the automotive industry, such as instrument panels, interior accessories, window frames, etc.

3. Medical device field. PP plastic is a non-toxic, tasteless, medical grade engineering plastic with good corrosion resistance and temperature resistance. Therefore, it is widely used in the field of medical devices, such as medical syringes, infusion sets, surgical instruments, etc.

4. Packaging field. PP plastic has good transparency and mechanical properties, so it is widely used in packaging fields, such as food packaging, cosmetic packaging, daily chemical packaging, etc.

To sum up, PP plastic is an excellent engineering plastic with excellent physical properties, chemical stability and thermal stability, and is an environmentally friendly plastic. It is widely used in various fields, such as automobile industry, medical equipment field, packaging field, etc. In the future, the application prospect of PP plastics is broader, and more fields will be applied to PP plastics.
