On your next time you'll be cutting green vegetables on your own chopping board, take a moment and look at it, the material most likely to be used as a High Density Polyethylene Cutting Board Material - Sheets cutting board is Polyethylene. Simply because it should be FDA and high quality guaranteed NSF approved as well as stain, moisture and odor resistant, Polyethylene is the best choice for cutting boards.
Various other cutting boards manufactured from wood are predisposed to bacteria and long term odors given that they lack the sought afterproperties that Polyethylene sheets offer, which include its non porous work surface, chemical resistance and approval for food contact. HD Polyethylene is an extremely durable and light-weight material that comes in a lot of forms and is ideal for a wide variety of applications. There are a few forms of Polyethylene commercially accessible. The most typical are HDPE (High Density Polyethylene), Low Density Polyethylene, and UHMW (Ultra High Molecular Weight Polyethylene). The differences have to do with the molecular weight and branching; this occurs when a monomer or atom is replaced by a longer chain of polymers (a very long repeating chain of atoms).

High Density is normally used for milk jugs and Tupperware style food containers. Low Density is typically used for water bottles and plastic bags. UHMW, which has higher molecular weight (2-6 million) which enables for an even transfer over the length of material which makes it stronger, so that it is able to be used with regard to bearing usages due to the great wear resistance. Commonly utilized in the food processing and dairy industry, UHMW is an effective replacement for various other industrial materials in addition to a great technique to many wear issues. Each one of these polymers are produced from the same polyolefin plastic materials family, but they all have certain properties that make them just a little different. HDPE provides great chemical resistance, with higher impact strength and great energy absorption. Low Density Polyethylene has several of the same properties as High Density but it is not as dense at 9.15, opposed to HDPE which is 9.34, as well as being a softer material ( one gallon coffee can lids). Further, it provides a lower tensile strength as well as better, easier heat forming.
UHMW is really a strong material with 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 Polytetrafluoroethylene - PTFE; which has a higher temperature and chemical resistance. The UHMW Polyethylene offers a lot of material selections and properties, and all these products possess fantastic strength which might be suitable for numerous applications. From the food industry to automotive, your kitchen or even the warehouse, whatever your Polyethylene needs are - High Density, Low Denseness or even UHMW, Polyethylene makes a great option.
