Summary

Polypropylene is often referred to as a “commodity resin”, however, is this really the case?

Polypropylene is a versatile thermoplastic that can be processed through a variety of processing techniques. It is utilized in a wide range of applications, including packaging, automotive, infrastructure, appliances, healthcare, and electrical. It’s wide use is based upon several key strengths, including:

• Good chemical resistance
• Good electrical insulation properties
• Flexural strength and modulus
• Relatively low coefficient of friction
• Readily available and relatively inexpensive

The implication of the interchangeability of polypropylene resins does a disservice to the complexity of this material and the plastic industry in general. The properties of polypropylene are highly dependent on molecular weight and molecular weight distribution, crystallinity, type and proportion of comonomer and the tacticity.

Hopefully, at the conclusion of the webinar, attendees will

• Gain an understanding of the general properties of polypropylene.
• Have more insight into how the molecular structure of polypropylene determines its performance properties.
• Appreciate the diversity of polypropylene.
