The next time you may be slicing green veggies on the cutting board, spend some time and look at it, the material most likely to be used as a High Density Polyethylene Cut Grade Material - Sheets cutting board is Polyethylene. Simply because it can be FDA and NSF approved not to mention stain, moisture and odor resistant, Polyethylene is an ideal choice for chopping boards.
Other kinds of cutting boards manufactured from wood are at risk to bacteria and long term odors because they lack the desiredproperties that Polyethylene sheets offer, which include its non permeable work surface, chemical resistance and approval for food contact. Polyethylene certainly a durable and lighter weight material that comes in many forms and is ideal for a range of applications. There are various varieties of Polyethylene commercially accessible. The most common are HDPE (High Density Polyethylene), Low Density Polyethylene, and UHMW (Ultra High Molecular Weight Polyethylene). The only difference has to do with the molecular weight and branching; this occurs when a monomer or atom is replaced by a longer chain of polymers (a long repeating chain of atoms).
The High Density is commonly used for milky white gallon milk jugs and common food containers. Low Density is often used for milky colored bottles in addition to plastic grocery bags. UHMW, which has higher molecular weight (2-6 million) which allows for an even transfer over the length of material which makes it stronger, making it able to be used for bearing applications for the great wear resistance. Regularly employed in the food processing and dairy industry, Ultra High Molecular Weight Polyethylene is really a good replacement for various industrial materials as well as a great method for fixing many wear issues. These polymers are derived from the same polyolefin plastic family, but all have certain properties that make them a little different. HDPE provides great chemical resistance, with extreme impact strength and great energy absorption. LDPE has lots of of the same properties as High Density but it's not as dense at 9.15, the lowest in comparison to HDPE which is 9.34, as well as being a softer material ( the soft coffee can lids). Additionally it has a lower tensile strength and superior, more convenient formability.
UHMW can be described as strong material that has great durability and low co-efficient of friction rendering it an ideal for sliding applications. The only plastic material with a lower co-efficient of friction is Teflon - PTFE; which has a higher temperature and chemical resistance. UHMW Polyethylene delivers a wide range of material alternatives and properties, and these materials have fantastic longevity which really can be worthy of numerous applications. From the food industry to automotive, the kitchen or maybe the warehouse, whatever your Polyethylene needs are - High Density, Low Density or even UHMW, Polyethylene is really a good option.
