What is Polypropylene?

Polypropylene (PP) is a thermoplastic polymer that can be classified into two main categories Polypropylene Homopolymer and Polypropylene Copolymer. The primary difference between PP homopolymer and PP copolymer lies in their molecular structure and arrangement of the polymer chains.

About Polypropylene Homopolymer

Polypropylene homopolymer (PPH) is the most widely utilized in the polypropylene family. PPH offers a high strength to weight ratio and boasts excellent stiffness, superior scratch resistance and good chemical resistance against most inorganic acids, alkalis and salts. Polypropylene homopolymer has superb weldability characteristics that allow this material to be used in many corrosion resistant structures.

Benefits of Polypropylene Homopolymer (PPH)

Polypropylene homopolymer generally exhibits high crystallinity, which results in greater stiffness. It tends to have better mechanical strength, chemical and thermal resistance than copolymers.



Excellent Stiffness

PP homopolymer exhibits high stiffness and strength, making it suitable for applications where structural integrity and rigidity are essential. This property is particularly beneficial in products like pipes, automotive components, and structural parts.

Low Moisture Absorption

Polypropylene homopolymer has low moisture absorption, making it resistant to water and humidity. This property is advantageous in applications where exposure to moisture could compromise the material's performance, such as outdoor applications and certain packaging.

FDA Approval for Food Contact

PP homopolymer is often approved by regulatory authorities, including the U.S. Food and Drug Administration (FDA), for use in food contact applications. This makes it suitable for producing food containers, packaging, and utensils.

Lightweight Nature

Polypropylene homopolymer is a lightweight material, which is advantageous in applications where weight reduction is essential. This is particularly relevant in automotive components, where lighter materials can contribute to fuel efficiency.

About Polypropylene Copolymer

Polypropylene copolymer (PPC) is a bit softer than PPH, but it has greater impact strength and is tougher and more durable than homopolymer polypropylene. Copolymer polypropylene tends to have better stress crack resistance and low-temperature toughness than homopolymer at the expense of small reductions in other properties.

Benefits of Polypropylene Copolymer (PPC)

Polypropylene copolymer (PP-C) is another polypropylene variant produced through copolymerization of propylene with a second monomer, typically ethylene. PP copolymer balances stiffness and impact resistance, making it suitable for applications that combine these properties. This balance makes it versatile for use in various consumer and industrial products.

Enhanced Impact Resistance

One of the primary benefits of polypropylene copolymers is their improved impact resistance compared to homopolymers. Incorporating ethylene in the polymer chain imparts greater flexibility and toughness, making it suitable for applications that require resistance to impact and stress.


Better Stress Crack Resistance

The copolymer structure enhances stress crack resistance, making PP copolymer suitable for applications where the material is subjected to dynamic or repetitive stresses. This property is advantageous in products like living hinge components and containers.

Greater Flexibility

Polypropylene copolymer is more flexible than homopolymer, making it suitable for applications that require bendability and flexibility. This characteristic is valuable in products like flexible packaging, tubing, and specific molded components.

Chemical Resistance

Like homopolymer, PP copolymer maintains good chemical resistance. This property makes it suitable for use in applications where chemical exposure is a concern, such as in chemical-resistant linings, containers, and pipes.

FDA Approval for Food Contact

Polypropylene copolymer is often approved by regulatory authorities, including the U.S. Food and Drug Administration (FDA), for use in food contact applications. This makes it suitable for producing food containers, packaging, and utensils.

Suitable for Living Hinge Applications

The flexibility and toughness of PP copolymer makes it well-suited for living hinge applications. Living hinges are thin, flexible sections of material used in products like caps, lids, and closures.
