PP Sheet Full Form

PP stands for polypropylene. It is also known as polypropylene. It is a polymer which that is used in many applications. These sheets are more resistant to chemicals and some solutions like salts, acids, and bases. It was first polymerized in 1951 by two scientists, Paul Hogan and Robert Banks. By 1957, the popularity of polypropylene increased and the products began across Europe. At present it has become one of the most produced plastic products in the world. Polypropylene sheet is nothing but a chemically resistant plastic.

It can be welded easily using a thermoplastic welding machine. It is fabricated into water and chemical tanks. These sheets have significant obstruction against any water sheets. These sheets are harder and highly resistant to heat, and the properties of polypropylene are similar to those of polyethylene. Syndiotactic was the first produced polypropylene by Natta.

Characteristics of Polypropylene

The most common properties of polypropylene are:

• Elasticity: It has a high elasticity property over a certain range of deflection.

• Toughness: The deformation of this material is done very easily, so it is a tough material.

• Chemical Resistance: Polypropylene doesn’t react with dilute acids and bases. So it is used for containers of such cleaning agents and liquids.

• Insulation: Polypropylene is highly resistant to electricity and used for the electronic components.

• Fatigue resistance: It maintains its shape even after a high bending or flexing.

• Transmissivity: It is used where there is a need for some light transfer.

Advantages of Polypropylene sheets

The major advantages of polypropylene sheets are:

• Hard, stiff and tough material

• Available in different formats and thicknesses,

• Thermoformable material

• Moisture resistant

• High impact resistant

• Scratch resistance material

• Food grade material

• Readily available and less expensive

• It has a slippery surface

Disadvantages of Polypropylene sheets

Some of the disadvantages of polypropylene are listed below:

• High thermal expansion coefficient that limits its high temperature applications

• Susceptible to UV radiation

• Poor resistant to chlorinated solvents

• Highly explosive and flammable

• Susceptible to oxidation

• Difficult to paint because of its poor bonding properties
