Sheets that consist of polypropylene are utilized in a wide variety of applications, such as manufacturing equipment for labs, creating labels and manufacturing loudspeakers, and the polymer is also used to make shelves of all colors. These products can generally resist the damaging impact of chemicals more effectively than items that are made of standard plastic.
The material was first created in 1951. By 2008, enterprises were selling 45.1 million tons of polypropylene per year, and these companies generated annual earnings of $65 million in total. According to several studies, the sales of polypropylene will produce $145 million in revenue by 2019.
The Material’s Properties
Polypropylene is particularly dense, yet it is quite flexible. In order to further increase its toughness, some enterprises add ethylene to the material. The polymer will not become chipped and is especially resistant to pressure, and as a result, it is commonly used to insulate pipes. Moreover, polypropylene is rarely affected by high temperatures.
Unlike the colors of some types of plastic, the tone of the material usually does not fade over time. If color is not added, the material is generally translucent.
Resistance to Ultraviolet Rays
Polypropylene is not impacted as negatively by ultraviolet radiation as standard plastic. Furthermore, numerous studies have shown that UVA rays can’t permeate the material as deeply as they are able to penetrate paper and cloth.
Several types of molding consist of polypropylene. The material is commonly found in chairs, and due to its durability, certain companies use it to manufacture brackets that hold lights in place.
Many enterprises purchase PP sheets online in order to create large signs that will be placed outdoors or behind windows, and certain companies put sizable lights directly behind the advertisements. Some businesses add fillers to the signs that cause the polypropylene to be more resistant to fire.
Numerous types of auto parts are made of polypropylene, and some of these include housings for electrical components, interior trims and liners that are positioned underneath the fenders. According to one analysis, polypropylene is found in at least 27 percent of the cases that hold automotive batteries.
Packaging and Containers
The material is utilized to make bags and several types of boxes. When shipping valuable items, many companies place thick films that are made of the polymer around the objects in order to prevent them from becoming scratched. Packaging that solely consists of polypropylene may have a reduced impact on the environment because the material is fully recyclable.
