What is polypropylene?

Polypropylene (PP) is a distinct polyolefin, slightly more robust than polyethylene.This versatile commodity plastic boasts low density and remarkable heat resistance, making it ideal for packaging, automotive, consumer goods, medical applications, cast films, and more. Its molecular formula is represented as (C₃H₆)_n. Polypropylene is flexible in its processing, accommodating virtually all methods. The most prevalent processing techniques include:

Injection Molding with PP

When embarking on PP injection molding consider the following crucial conditions:

1. Melt temperature ranges optimally from 200-300°C
2. Mold temperature should be set between 10-80°C
3. As long as storage is proper, drying is a non-essential step
4. Elevated mold temperature significantly enhances part brilliance and appearance
5. Mold shrinkage rates fall between 1.5 and 3%, influenced by:
   • specific processing conditions,
   • polymer rheology, and
   • the thickness of the end product

PP Tips

How is PP Produced? Unveil the fascinating journey of Polypropylene production!

Polypropylene is meticulously crafted through the polymerization of propene monomer, unlocking its versatile capabilities. There are two primary, innovative synthesis methods to produce high-quality polypropylene:

• Ziegler-Natta polymerization, a traditional and trusted approach,
• or Metallocene catalysis polymerization, a cutting-edge technique.

Upon polymerization, PP can form three distinct chain structures, each defined by the strategic placement of methyl groups:

• Atactic (aPP): Distinguished by an - Irregular methyl group (CH₃) arrangement, offering unique properties.
• Isotactic (iPP): Characterized by - Methyl groups (CH₃) uniformly aligned on one side of the carbon chain, enhancing its strength.
• Syndiotactic (sPP): Features an - Alternating methyl group (CH₃) arrangement, providing distinct flexibility.

Basic Chain Structures of PP: A key to unlocking diverse material characteristics.

Depending on its production and formulation, polypropylene exhibits a remarkable range of characteristics:

• It can be tailored to be hard or soft,
• opaque or transparent, offering aesthetic versatility,
• light or heavy, optimizing for weight-sensitive applications,
• insulating or conductive, for dynamic electrical applications,
• and can be used neat or reinforced with various materials-be it cost-effective mineral fillers, short or long glass fibers, natural fibers, or even self-reinforced for enhanced performance.

What are the Properties of PP? Discover the exceptional traits that make polypropylene a standout material choice!

PP - Main Types & Their Comparison

What are the types of PP?

The major types of polypropylene available in the market are as follows:

Polypropylene Homopolymer

PP Homopolymer This is the most widely utilized general-purpose grade of polypropylene. It is composed solely of propylene monomer in a semi-crystalline solid form. Its primary applications span across packaging, textiles, healthcare, pipes, automotive, and electrical sectors.

Polypropylene Copolymer

This category is crafted by polymerizing propene and ethane. It is further sub-divided into random copolymers and block copolymers.

1. PP Random Copolymer These are produced by polymerizing ethene and propene together, typically featuring ethene units up to 6% by mass. These units are intricately integrated into the polypropylene chains. The result is a polymer that is flexible and optically clear. Such properties make these polymers ideal for applications necessitating transparency and an excellent visual appearance.


2. While in PP Block Copolymer, a higher ethene content ranging from 5% to 15% is present. Its co-monomer units are arranged in regular patterns or blocks. This regularity results in a thermoplastic that is tougher and less brittle than its random counterpart. These polymers excel in applications requiring high strength, especially in industrial settings.

The potential applications of PP homopolymer and PP copolymer are nearly equivalent. Due to their extensively shared properties, the decision between these two materials often hinges on non-technical criteria, some of which are highlighted in the table below.

PP Homopolymer	PP Copolymer
High strength-to-weight ratio and stiffer & stronger than copolymer Good chemical resistance and weldability Good processability Good impact resistance Good stiffness Food contact acceptable Suitable for corrosion-resistant structures	Bit softer but has better impact strength; tougher and more durable than homopolymer Better stress crack resistance and low-temperature toughness High processability High impact resistance High toughness Not preferable for food contact applications

Polypropylene, Impact Copolymer

Propylene Homopolymer is enhanced with a co-mixed PP Random Copolymer phase, featuring an ethylene content of 45-65%. It is excellent for parts that require superior impact resistance. Impact copolymers are predominantly used in packaging, houseware, film, and pipe applications. They also find extensive use in the automotive and electrical sectors.

How to process PP?

Polypropylene is exceptionally versatile and can be processed using virtually all processing methods. The most common techniques include:

Injection Molding with PP

The processing conditions for PP injection molding are as follows:

1. Melt temperature: 200-300°C
2. Mold temperature: 10-80°C
3. Drying is not necessary if stored adequately
4. A higher mold temperature enhances the brilliance and appearance of the final part
5. Mold shrinkage for our Premium Recycled Polypropylene Resin is expertly managed to fall between 1.5 and 3%. This precision is influenced by:
   • the meticulous processing conditions,
   • the sophisticated rheology of the polymer, and
   • the carefully considered thickness of the final piece.

Sustainability Aspect of PP: A Journey Towards a Greener Future
Is PP recyclable? The definitive answer is:
Yes, PP is 100% recyclable, embodying a commitment to environmental responsibility.

All plastics are identified by a 'Resin Identification Code/Plastic Recycling Code' that reveals the type of resin used. Our Polypropylene stands proud with a code of 5, signaling its 100% recyclability.


Polypropylene recycling process: From Waste to Worth

Our innovative PP recycling process includes these crucial steps:

Initially, waste plastic is expertly melted at a high temperature of 250°C, effectively eliminating contaminants.
Subsequently, residual molecules are efficiently removed under vacuum, followed by solidification at around 140°C.

The resulting high-quality recycled PP can be seamlessly blended with virgin PP at an optimal rate of 50%, ensuring strength and durability.


PP recycling - Overcoming the Main Challenge

The primary challenge in PP recycling is its lower consumption rate. Currently, only 1% of PP bottles are recycled, a stark contrast to the impressive 98% recycling rate of PET & HDPE bottles combined. Our mission is to close this gap.
