Polypropylene Sheet is another very useful and versatile engineering plastic that has many uses within many varied industries and applications. Polypropylene Sheet has replaced many other plastics and resulted in reduced costs and improved performance for many component manufacturers.

Polypropylene Sheet Applications
Polypropylene Sheet is often used for lining or complete manufacture of acid and chemical tanks and Polypropylene is also sometimes used as back or chopping boards within the packing industry as it helps when the sharpened cutters penetrate the cardboard and acts as a substrate for the cutters edges. Polypropylene Sheet is also well known for its uses within the prosthetic industry as Polypropylene can be heated and molded to an excellent shape to particularly enable foot, leg or other limb supports being produced accurately. Another useful application for Polypropylene Sheet is the use within clean rooms for cladding walls and creating a durable barrier that is both tough and resistant to strong cleaning fluids. Other useful applications for Polypropylene Sheet include swimming pools due to its chlorine and water resistance and also battery boxes, this is due to Polypropylene having excellent acid resistance.

Polypropylene Sheet Grades
Polypropylene Sheet has two particular grades and they are Homopolymer grade Polypropylene and also copolymer grade Polypropylene. Homopolymer is a harder and more rigid grade that is available in natural and beige colour and has a larger range of size availability. Copolymer grade Polypropylene Sheet is more flexible and malleable, has better low temperature impact performance and is available in a much greater range of colours.

Polypropylene Sheet Sizes
Homopolymer grade Polypropylene is generally manufactured in sheet sizes of 2000mm x 1000mm and also 3000mm x 1500mm, the thickness range is generally from 1mm up to 50mm thick.

Copolymer grade is generally manufactured in sheet sizes of 2440mm x 1220mm and also 3000mm x 1500mm, the thickness range is generally from 1.5mm up to 15mm thick, although the above is the typical manufactured sizes, Polypropylene Sheet can sometimes be obtained in longer sizes to special order.

Polypropylene Sheet Advantages
Polypropylene Sheet is very light weight and has a density of only 0.91g/cm3 and is a plastic that actually floats and also can help with handling where large components are employed. Polypropylene Sheet also has a very low moisture absorption and at 0.03, this can improve product and component stability and also helps with bacterial resistance. Polypropylene Sheet has excellent acid and chemical resistance which helps in the production of chemical and acid tanks and also acid resistant seals. Polypropylene Sheet can also be easily shaped, formed and vac formed, this allows this material to be used in the fabrication industry and will produce high quality items that are used in many varied industries including automotive. Polypropylene Sheet is also very economical and can have equal performance of other materials at a much lower price. Polypropylene Sheet is almost impossible to bond with current adhesives, although future adhesives in this area may change this situation, until this time, Polypropylene can be welded with simple welding equipment and welding rod.

Polypropylene Sheet Manufacturing Process
Polypropylene Sheet is produced in two specific ways which is extruded sheet and also a process known as pressed, this latter process most commonly involves the sheet being planed. Extruded Polypropylene Sheet is a process that involves heating polymer to melting point and then extruded through dies/rollers to produce an accurate sheet. Pressed Polypropylene Sheet is a more expensive sheet but because this process does not involve the stress inducing extrusion process, it produces a material that is much more stable and after being machines into intricate components, remains more accurate due to reduced internal stress.
