Polypropylene is a thermoplastic made from the combination of propylene monomers, and is today one of the most commonly produced plastics in the world. Product Components Corporation is proud to offer many Polypropylene products to its valued customers.
Polypropylene has a more slippery surface than Acetal and other plastics, guaranteeing lower friction in applications like gearing and furniture (and other manufacturing) contact points. However, that smoothness also makes it difficult for to bond and adhere well to certain glues used in manufacturing.
There are many other advantages of Polypropylene, including:
• Low density, more lightweight than other plastics
• Resistance to organic solvents, fats at room temperature, and oxidation at higher temperatures
• Ability to be manufactured (via several methods) into a living hinge, which are used in non- or low-load bearing applications like the snapping lids on ketchup and shampoo bottles, meaning it won’t break when repeatedly bent with ordinary force
• Superior insulating capabilities, making it ideal for cooler bags, tumblers, thermoses and other like products, as well as electrical and cable insulation
• Floats, quick drying, mold-resistant, doesn’t absorb water, so good for marine and outdoor use
• Massively produced therefore relatively inexpensive
• High flexural strength due to its semi-crystalline nature
• Good fatigue resistance
• Good impact strength
• Tensile strength of 5,800 PSI
• Although Polypropylene can be made transparent, its normal production results in a natural, opaque color. Thus, it is a good option where some transfer of light is either necessary or of aesthetic value.
• Myriad other diverse applications, such as car bumpers, chemical tanks, gas cans, carpet fibers – and more!
There are, of course, some disadvantage inherent in Polypropylene, including: a high thermal expansion coefficient which limits its high temperature applications; susceptible to UV degradation; poor resistance to chlorinated solvents and aromatics; difficult to paint as it has poor bonding properties; highly flammable.
BUT: with its positive attributes far outweighing the negatives, Polypropylene is an ideal material choice for a wide range of projects. To learn more about Polypropylene and its advantages and uses, please call Mary at Product Components Corporation at (800) 336-0406.
