HDPE as a nsf approved cutting board
Next time you're chopping fruits and vegetables on the slicing board, take the time and look at it, the material most likely to be used as a HDPE Polyethylene Cutting Board - Sheets cutting board is Polyethylene. Because it should be FDA and National Sanitation Foundation approved as well as stain, moisture and odor resistant, Polyethylene is the best choice for chopping boards.
Many cutting boards cut from wood are vulnerable to bacteria and residual odors because they lack the desiredproperties that Polyethylene sheets offer, such as its non permeable work surface, chemical resistance and approval for food contact. Polyethylene material is certainly a durable and light-weight material that comes in lots of forms and is great for a wide variety of applications. There are various varieties of Polyethylene commercially available. The most typical are HDPE (High Density Polyethylene), LD Polyethylene, and UHMW (Ultra High Molecular Weight Polyethylene). The 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 very long repeating chain of atoms).

The High Density Polyethylene is frequently used for the standard gallon sized milk jugs and common food containers. Low Density happens to be used for packaging as well as plastic grocery bags. UHMW, which has higher molecular weight (2-6 million) that allows for an even transfer over the length of material which makes it stronger, so that it is able to be used for bearing applications for the great wear resistance. Very popularly used in the food processing and dairy industry, UHMW makes a great replacement for numerous industrial materials in addition to a fantastic treatment for many wear issues. All these polymers are made from the same polyolefin plastic materials family, but all have certain properties that make them a little different. HDPE provides great chemical resistance, has higher impact strength and great energy absorption. LD Polyethylene has many of the same properties as High Density yet it's not as dense at 9.15, whereas HDPE which is 9.34, in fact it is a softer material ( the soft coffee can lids). Further, it features a lower tensile strength as well as greater, easier formability.
UHMW is really a strong material which has great durability and low co-efficient of friction which make it an ideal for sliding applications. The best known material plastic material with a lower co-efficient of friction is Polytetrafluoroethylene - PTFE; which has a higher temperature and chemical resistance. The UHMW Polyethylene is designed with a lot of material possible choices and properties, and these materials have outstanding toughness which might be worthy of several applications. From the food industry to automotive, your home or maybe the warehouse, whatever your Polyethylene needs are - High Density, Low Denseness as well as UHMW, Polyethylene makes a great decision.
