Natural and White Polypropylene Sheet and Sheets
Polypropylene Sheet and Sheets come in Natural and White
Let’s start by clarifying what Natural and White means. The natural color of Polypropylene is a translucent straw color, not yellow – not white, more of a very lite translucent – almost transparent beige. The white color is a bright white with a slight blue tint, or blue white. This white color is opaque, and is a white color that blends well with other materials. Polypropylene sheet is also available in the color Black.
Polypropylene sheet materials are available in an opaque black color as well. There is also a grade of Polypropylene sheets that carries a FR – UL 94 V-0 rating. When fabricating a ‘wet bench’ for the electronic industry, the new requirement is FM4910. This new specification is from Factory Mutual Insurance, and the requirements are very stringent. The purpose of this specification is that the FM4910 means it won’t burn, and will put off no toxic fumes or excessive smoke.
This rigid plastic sheet can be cut with standard cutting tools, drilled, routed, machined and processed easily. Clean and sharp tools will provide a clean cut, and occasionally will produce stringy burrs that are easy to remove with standard deburring tools. It fabricates very much like HDPE (High Density Polyethylene Sheet), and has many similar properties. The chemical resistance of Polypropylene approaches the excellent resistance of Dupont PTFE Sheet.
Polypropylene sheet materials have excellent chemical resistance
The main claim to fame for polypropylene in sheet is the excellent chemical resistance. This material is used extensively in the manufacture of chemical tanks. This chemical resistance means also that it can not be bonded together (glues and cements peel right off!), and thus it must be ‘welded’ together for fabrication. The preferred method of welding is a hot air welder – which supplies a fine stream of very hot air on the exact area that you may wish to weld together. This weld, when done properly will yield a very strong bond, and will enable a water tight tank or box to be fabricated.
This great building block material can be used in numerous industrial and chemical type applications. The list of great properties is extensive, here are a few of the highlights:
- Self Lubricating and Low Co-Efficient of Friction
- High Chemical Resistance
- Abrasion, Moisture and Electrical Resistance
- Stiffness, Rigidity, or Cut Resistance
- Low Specific Gravity (Floats in Water)
Polypropylene sheet and sheeting provide years of use, and can be cleaned with most chemical cleaners. Sheets are available in thicknesses ranging from .032″ – 2.0+ thick, and standard sheet sizes are 48″ X 96″ and 48″ X 120″, plus other sizes can be special run.
