Polypropylene Cartridges - High Heat Resistance At 320â°f, Ideal For Moisture-prone Environments - Durable And Easy To Dye

The melting point of polypropylene cartridges is very high compared to many other plastics, at 320A F (160A C), which means that the hot water used when washing dishes will not cause polypropylene dishware to warp. This contrasts with polyethylene, another popular plastic for containers, which has a much lower melting point. Polypropylene is also very easy to add dyes to, and is often used as a fiber in carpeting which needs to be rugged and durable, such as the carpet one finds around swimming pools or paving miniature golf courses. Unlike nylon, which is also often used as a fiber for rugged carpeting, polypropylene doesn't soak up water, making it ideal for uses where it will be constantly subject to moisture.
