Most of the thin sheets of polypropylene are used as a dielectric within specified high-performance pulse and low-loss RF capacitors.
Polypropylene can be used in the manufacturing piping systems; both ones concerned with high-purity which designed for strength and rigidity (e.g. those intended for use in potable plumbing, hydronic heating and cooling, and reclaimed water). This kind of material is usually chosen for its resistance to corrosion and chemical leaching, its resilience against most forms of physical damage, containing effect and freezing, its environmental advantage, and its ability to be joined by heat fusion rather than gluing.
Many items which can be made by polypropylene using in medical or laboratory because it can withstand the heat in an autoclave. heat stability also enables it to be used as the manufacturing material of consumer-grade kettles. Food containers cannot be melt in the dishwasher, and do not melt during industrial filling processes in hot condition. For this reason, most plastic tubs for dairy products are polypropylene sealed with aluminum foil cause those are heat-resistant materials. After cooling the product, the tubs are often given lids made of a less heat-resistant material, such as LDPE or polystyrene. Such containers provide a good hands-on example of the variance in modulus, since the rubbery (softer, more flexible) feeling of LDPE with respect to polypropylene of the same thickness is readily apparent. Rugged, translucent, recyclable plastic bottles made in a wide variety of shapes and sizes for consumers from various companies. although the lids are usually making from more flexible LDPE so they can snap on to the container to close it. Polypropylene is able to made disposable bottles to contain liquid, powdered, or similar consumer products, although HDPE and polyethylene terephthalate are normally used to make bottles. Plastic containers, car batteries, wastebaskets, pharmacy drug bottles, cooler containers, dishes and pitchers are frequently can be made from polypropylene or HDPE, both of which commonly have rather similar appearance, feel, and properties at ambient temperature.
A common usage for polypropylene is as biaxially oriented polypropylene (BOPP). Usually BOPP sheets are used to make a wide ranging of materials including clear bags. When polypropylene is biaxially oriented, it becomes crystal clear and can be an excellent packaging material for artistic and retail products.
Polypropylene, highly colorfast, is widely used in manufacturing carpets, rugs and mats to be used at home.
