Polypropylene Compounds. PP Compounds

Polypropylene is the second-most widely produced commodity plastic (after polyethylene) and it is often used in packaging and labeling. Polypropylene has similar properties as Polyethylene but its slightly harder and more heat resistant. These compounds are thermoplastic resins and are produced using a mixture of one or more base polyolefins with various components as impact modifiers, fillers and strengtheners (e.g. mineral fillers and glass fibre), pigments and additives.
