Basic Knowledge of Plastic: What is PP?

Basic Knowledge of Plastic: What is PP?

A type of material called "general-purpose resin" among synthetic resins (plastics)! Introducing the basics of plastic knowledge.

PP, read as polypropylene, is a polymer made of carbon and hydrogen. It is a crystalline polymer compound (plastic) with a regular arrangement of propylene (gas), and it is the lightest among plastics, commonly used in everyday items. It is a type of thermoplastic resin that has plasticity (it can be deformed when force is applied, and does not return to its original shape when the force is removed) when heat is applied. 【Features】 ■ A type of material referred to as "general-purpose resin" ■ The second highest production volume among synthetic resins ■ A crystalline polymer compound with a regular arrangement of propylene ■ The lightest plastic, with a specific gravity of 0.9 ■ Commonly used in everyday items ■ A type of thermoplastic resin *For more details, please refer to the PDF document or feel free to contact us.

Basic Knowledge of Plastic: Characteristics of PP

Basic Knowledge of Plastic: Characteristics of PP

Mass production is possible at low cost! Adopted in a wide range of fields such as automotive parts, food containers, and medical devices.

Here is an introduction to the characteristics of PP as basic knowledge of plastics. Being a thermoplastic resin, it deforms when heat is applied. Additionally, it is a material that tends to warp easily, so it is necessary to design products in shapes that are less prone to warping. However, it excels in chemical resistance, abrasion resistance, impact resistance, and lightweight properties, making it durable and resistant to scratches. As a result, it is widely used in various fields such as automotive parts, food containers, and medical devices. [Characteristics] - Has a specific gravity of 0.9, making it the lightest among general-purpose plastics - Excellent in chemical resistance, abrasion resistance, impact resistance, and lightweight properties - Durable and resistant to scratches - Can be mass-produced at low cost - Also used in household goods, miscellaneous items, and packaging materials *For more details, please refer to the PDF document or feel free to contact us.

Basic Knowledge of Plastics: Advantages and Disadvantages of PP

Basic Knowledge of Plastics: Advantages and Disadvantages of PP

It has excellent mechanical strength, a hard surface, and good wear resistance! Suitable for injection molding and extrusion molding, etc.

Here is an introduction to the advantages and disadvantages of PP as basic knowledge about plastics. Due to its specific gravity being lower than 1, it has a lightweight property that allows it to float on water. It is also less affected by chemicals, making it widely used in scientific instruments and medical devices. However, it generally has disadvantages such as being weak against ultraviolet rays, and it turns white when exposed to sunlight, making it unsuitable for outdoor use. However, improvements can be expected by adding additives such as antioxidants. 【Advantages】 ■ Lightweight ■ Heat resistance ■ Chemical resistance ■ Excellent mechanical strength ■ Can be mass-produced at low cost *For more details, please refer to the PDF document or feel free to contact us.

Basic Knowledge of Plastic: Types of PP

Basic Knowledge of Plastic: Types of PP

Classified into three types! Introducing homopolymers, random polymers, and block copolymers.

PP is classified into three types in the form of copolymerization with comonomers (primarily ethylene). The "homopolymer" has a high melting point and excellent heat resistance and heat water resistance; the "random polymer" has a low melting point and low rigidity, with excellent transparency and surface gloss; the "block polymer" excels in low-temperature impact strength and has a good balance of rigidity and impact resistance. If you have any requests or concerns regarding the recycling and commercialization of plastics, please feel free to contact us. 【Features】 <Homopolymer> ■ High melting point ■ Excellent heat resistance and heat water resistance ■ Poor cold resistance ■ Low impact strength ■ Melting point: 160–165℃ *For more details, please refer to the PDF materials or feel free to contact us.
