A large proportion of polypropylene production is melt-spun into fibres. Polypropylene fibre is a major factor in home furnishings such as upholstery and indoor-outdoor carpets. Numerous industrial end uses exist as well, includingropeand cordage, disposable nonwoven fabrics for diapers and medical ...
Limited resistance to aromatic and halogenated hydrocarbons and oxidizing agents Flammability:PP is a highly flammable material. PP retains mechanical & electrical properties at elevated temperatures. This occurs in humid conditions and when submerged in water. It is a water-repellent plastic. ...
The molecular weight and molecular weight distribution, crystallinity, form and proportion of comonomer (if used), and isotacticity all influence the properties of polypropylene. The methyl groups in isotactic polypropylene, for example, are oriented on one side of the carbon backbone. This structure...

It is a type of plastic that is known for its excellent combination of properties, such as high strength, chemical resistance, and low density. In this document, we will explore the key characteristics, uses, and processing methods of polypropylene. 1. Properties of Polypropylene Polypropylene is...
HDPE is a stronger, more rigid polymer that is often used in bottles, pipes, and buckets. Polypropylene vs. Polyethylene: Applications and Uses Both polypropylene and polyethylene are versatile polymers that can be used for many different purposes. Some common uses for polypropylene and polyethylene...
It has good chemical and stress crack resistance, is autoclavable, and has excellent dielectric properties. Polypropylene becomes brittle at low temperatures (typically below –32°C) and is not weather or radiation resistant unless additives and impact modifiers are compounded into it. Clear grades...
