High Density Polyethylene as a cutting surface
Next occasion you may be chopping green veggies on top of your slicing board, take the opportunity and look at it, the material most likely to be used as a High Density Polyethylene Cut Grade Material - Sheets cutting board is Polyethylene. Because it should be FDA and NSF approved and even stain, moisture and odor resistant, Polyethylene is an ideal choice for chopping boards.
Some other cutting boards constructed from wood are prone to bacteria and long term odors simply because they lack the sought afterproperties that Polyethylene sheets offer, including its non permeable work surface, chemical substance resistance and approval for food contact. HD Polyethylene most certainly a durable and lighter weight material that comes in numerous forms and is great for a wide range of applications. There are lots of varieties of Polyethylene commercially accessible. The most common are HDPE (High Density Polyethylene), Low Density Polyethylene, and UHMW (Ultra High Molecular Weight Polyethylene). The the main difference has to do with the molecular weight and branching;Â this occurs when a monomer or atom is replaced by a longer chain of polymers (an excessively long repeating chain of atoms).

The High Density Polyethylene is normally used for milk jugs and glad food storage containers. Low Density is frequently used for packaging or perhaps plastic baggies. UHMW, which has higher molecular weight (2-6 million) that allows for an even transfer over the length of material which makes it stronger, allowing it to be able to be used with regard to bearing purposes for the great wear resistance. Often employed in the food processing and dairy industry, Ultra High Molecular Weight Polyethylene is an effective replacement for numerous industrial materials as well as a great technique to many wear issues.  All these polymers are derived from the same polyolefin plastic family, but all have certain properties that make them just a little different. HDPE provides great chemical resistance, has exceptional impact strength and great energy absorption. LDPE has several of the same properties as High Density yet it's not as dense at 9.15, instead of HDPE which happens to be 9.34, in fact it is a softer material ( one gallon coffee can lids). It also has a lower tensile strength plus improved, simpler and easier formability.
UHMW is a strong material which includes great durability and low co-efficient of friction allowing it to be an ideal for sliding applications. Dupont makes the plastic material with a lower co-efficient of friction is Dupont Teflon - PTFE; which has a higher temperature and chemical resistance. Ultra High Molecular Weight Polyethylene features a lot of material choices and properties, and these types of materials have extraordinary longevity which might be properly suited for a number of applications. From the food industry to automotive, the kitchen and also the warehouse, whatever your Polyethylene needs are - High Density, Low Density or UHMW, Polyethylene is a nice alternative.
