PP (Polypropylene)

What is PP (Polypropylene)?

Thanks to its unique properties, PP is widely used in several industries, from the packaging industry to the automotive and construction sectors. Its combination of mechanical, chemical and thermal properties makes it particularly suitable for many different applications.

Important properties of PP (Polypropylene)

• Low density and light weight – PP is lightweight, making it easy to handle and transport without compromising strength.
• Good chemical resistance – The material is resistant to most acids, bases and solvents, making it ideal for use in chemical-resistant products and packaging.
• High temperature resistance – PP can be used at temperatures up to approximately 100°C without deforming, making it suitable for products exposed to heat.
• Impact resistance and flexibility – PP copolymer in particular is more flexible and has better impact resistance than the homopolymer, making it perfect for sports equipment and technical components.
• Excellent electrical insulation – Polypropylene has good insulating properties, making it useful in electronic components and cables.
• Easy to injection mold and process – PP can be easily shaped by injection molding, making it an ideal material for mass production of high-precision parts.
• Recyclable and more environmentally friendly than many other plastics – PP can be recycled and reused, reducing its environmental impact.

Different types of PP (Polypropylene) and their uses

Polypropylene is available in several different varieties, the most common of which are:

• PP Homopolymer – Has high stiffness and is often used in industrial applications, packaging, pipes and medical products.
• PP Copolymer – Divided into random and block copolymer.
• Random copolymer – Has better transparency and flexibility, often used in food packaging and medical products.
• Block copolymer – Has higher impact resistance and is used, for example, in the automotive industry, sports equipment and technical parts.

How do we use PP (Polypropylene) in our production?

We use PP in a variety of applications where its properties provide the best results.

Some of the most common uses are:

• Industrial components – Thanks to its chemical resistance and wear resistance, PP is used in technical parts for machines and production equipment.
• Packaging & containers – PP is used in packaging solutions, from food packaging to protective packaging, where low weight and hygiene are important factors.
• Sports and leisure products – In our collaborations with the sports industry, PP is used to create durable and lightweight details in sports equipment.
• Automotive industry – Polypropylene is used in several parts of vehicles, such as interior details, mudguards and air filter components.

Why do we choose PP (Polypropylene)?

PP is one of the most cost-effective materials and offers a balanced combination of strength, formability and chemical resistance. It is also one of the most recyclable plastic materials, making it a more sustainable choice.

By using different additives, we can optimize PP for specific applications, for example:

• Fiberglass reinforcement for increased stiffness and strength.
• UV stabilizers for better outdoor durability.
• Antistatic additives to reduce dust and dirt accumulation.

In summary, polypropylene is a versatile, durable and cost-effective material that we use in many different products to meet our customers' needs.
