Polyethylenes

Polyethylene is a lightweight material which does not absorb water and features good chemical resistance. Polyethylenes are used where componentry is required to be in direct contact with items of food, and is also made into parts subject to high impact stresses.
There are several grades of polyethylenes available, each having similar properties and capabilities. Polyethylenes are graded as per their molecular weight. As the grade or molecular weight of these plastic products increase, so does their quality, characteristics and performance. The different grades of polyethylene we supply are:

HDPE (High Density Polyethylene) – Polyethylene 300: 
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 weatherability are required. This is a good food grade general purpose polyethylene, making it a great choice for use as chopping/cutting boards in commercial kitchens.
HMWPE (High Molecular Weight Polyethylene – Polyethylene 500:
Featuring excellent mechanical properties, rigidity and creep resistance, making this polyethylene ideal for use in the food industry as underlays in food preparation, machined parts and conveyor line change parts.
UHMWPE (Ultra High Molecular Weight Polyethylene) – Polyethylene 7000:
Formulated for optimum sliding characteristics and resistance to wear and abrasion, this polyethylene is virtually unbreakable. In addition to its immense strength, UHMWPE reduces friction, clogging, noise and never needs lubrication. Problems with cohesive, wet or sticky materials can be overcome with the use of UHMWPE in various industrial situations ranging from fine foods to the mining industry. Polyethylene 7000 is rated better than carbon steel for sliding abrasion applications.
