Some examples of common products with PP are dairy and medication containers. Polypropylene is suitable for hot fill applications of up to 165°F and is therefore great for autoclaving. It is not recommended for cold or sub-freezing temperatures. The Cary Company has an assortment of polypropylene plastics available for purchase, such as plastic caps and jars, which have a higher tolerance for chemical products.
