Polyethylene Products
Polyethylene is available in several grades. All the grades have similar properties and perform along similar lines, but as the grades of these plastic products increase, so does the quality, performance and of course the price, as is the case with most plastic products and their grades. When the molecular weight increases in the polyethylene family, their characteristics also increase and enhanced performance is achieved. All the polyethylenes are lightweight and have good chemical resistance and do not absorb water. Polyethylenes are used where componentry is required to be in direct contact with food stuffs and also is made into parts subject to high impact stresses. Some of the different grades of polyethylene are listed below with a few of their specific applications and benefits.

HDPE Product Description
Polyethylene 300 (HDPE – High Density Polyethylene) is a rigid material which is available in large sheets for general use in plant engineering, tank construction and the wastewater industry, where all round chemical resistance and weather ability are required. This is a good food grade general purpose polyethylene, making it a great choice for use in commercial kitchens.
Key Features and Benefits of Polyethylene 300:
- Excellent abrasion resistance
- Very low co-efficient of friction
- Very high surface release properties
- High chemical resistance
- Excellent impact resistance
- Very good damping properties
- Good wear resistant material
- Cheaper than nylon
- Weldable (suitable for fabrication)
- Light weight (easy to handle without special equipment)
- Physiologically inert (approved for food applications)
- Electrical insulation
- Weatherproof
- Chemical resistance - resists corrosive chemicals (e.g. Sulphuric Acid, Caustic Soda)
- Withstands temperatures of –50 to +80 degrees centigrade
Applications of Polyethylene 300:
- Componentry in direct contact with foodstuffs
- Cutting and chopping boards
- Commercial cutting boards in abbatoirs, meat works and fish markets
- Spacers between steel plates
- Washers
- Butchers preparation tables
- Poultry processing plants
