Polypropylene, also known as PP, is a thermoplastic polymer that is widely used in different industries for its excellent chemical and mechanical properties. PP is considered as one of the most versatile and cost-effective polymers due to its high melting point, stiffness, toughness, and resistance to chemicals, UV light, moisture, and impact. In this blog, we will discuss the various applications of Polypropylene, its types and grades, and the leading PP supplier in Japan.
Types and Grades of Polypropylene
PP is classified into three types based on its molecular weight and morphology: Homopolymer, Random Copolymer, and Block Copolymer. Homopolymer PP is the most common type, which is used in applications where rigidity and strength are required, such as packaging, automotive, and construction. Random Copolymer PP has a higher clarity and flexibility, which makes it suitable for applications such as food containers, films, and medical devices. Block Copolymer PP has high impact strength and low-temperature resistance, which makes it ideal for automotive parts and appliances.
PP is also divided into different grades based on its melt flow rate (MFR), density, and additive content. The most commonly used grade is PP-Homopolymer QP83N, which has a high MFR of 56 g/10 min, a density of 0.905 g/cm3, and is suitable for injection molding and extrusion applications. PP grades with higher MFR, lower density, or with additives such as glass fiber, talc, or mineral fillers, are also available for specific applications.
Applications of Polypropylene
PP is a popular choice for various applications due to its excellent properties, cost-effectiveness, and ease of processing. Some of the significant applications of PP are listed below:
Packaging: PP is widely used for packaging applications due to its excellent strength, lightweight, and resistance to moisture and chemicals. PP packaging includes bottles, caps, containers, bags, films, and wraps used in industries such as food, beverage, healthcare, and consumer goods.
Automotive: PP is used in the manufacture of automotive components due to its low cost, durability, and weight reduction benefits. PP automotive applications include bumpers, interior trims, air intake manifolds, radiator grills, and battery cases.
Construction: PP is used in the construction industry as a building material due to its excellent strength, stiffness, and resistance to weather and chemicals. PP construction applications include pipes, fittings, roofing sheets, geotextiles, and insulation materials.
Electrical and Electronics: PP is used in the manufacture of electrical and electronics components due to its excellent electrical insulation and thermal resistance properties. PP E&E applications include wire and cable jackets, switch housings, and capacitor films.
Medical: PP is used in the medical industry due to its biocompatibility, sterilizability, and low toxicity. PP medical applications include syringes, IV bags, surgical instruments, and disposable medical devices.
