Much like Acetal, polypropylene is a plastic with a naturally glossy surface when properly manufactured. Its chemical resistance and elastic properties make it useful for a wide variety of food-related applications, including plastic kitchenware, dishwasher safe plates, and storage containers. Polypropylene is also commonly used to make toys, hard luggage containers, and even external car parts.

Advantages of Polypropylene:

1. Chemical Resistance – doesn’t react with most bases and acids
2. Fatigue Resistance – retains its shape after a lot of bending and flexing
3. Electrical Resistance – strong insulation properties
4. Elasticity – can bend, flex and deform without actually breaking
