HD Polyethylene as a FDA approved cutting board
During your next time you're slicing fruit and vegetables on the cutting board, spend some time and look at it, the material most likely to be used as a HDPE Polyethylene Cutting Board Material - Sheets cutting board is Polyethylene. Because it is normally FDA and National Sanitation Foundation approved in addition to stain, moisture and odor resistant, Polyethylene is an ideal choice for chopping boards.
Many cutting boards made of wood are prone to bacteria and residual odors given that they lack the desiredproperties that Polyethylene sheets offer, which include its non permeable surface, chemical substance resistance and approval for food contact. Polyethylene material is certainly an durable and lightweight material that comes in many forms and is perfect for a wide variety of applications. There are many different types of Polyethylene commercially available. The most common 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;Â which is when a monomer or atom is replaced by a longer chain of polymers (a very long repeating chain of atoms). Â

High Density Polyethylene is frequently used for the standard gallon sized milk jugs and glad food storage containers. Low Density happens to be used for containers in addition to plastic sandwich bags. UHMW, which has higher molecular weight (2-6 million) that enables for an even transfer over the length of material which makes it stronger, rendering it able to be used with regard to bearing uses for its great wear resistance. Typically employed in the food processing and dairy industry, Ultra High Molecular Weight Polyethylene is a brilliant replacement for various industrial materials as well as a great means to many wear issues.  All these polymers are produced from the same polyolefin plastics family, but they all have certain properties that make them just a little different. HDPE provides great chemical resistance, has very high impact strength and great energy absorption. Low Density Polyethylene has many of the same properties as High Density but it is not as dense at 9.15, the lowest in comparison to HDPE which happens to be 9.34, and is also a softer material ( the soft coffee can lids). Additionally, it features a lower tensile strength and better, simpler and easier heat processing.
UHMW is definitely a strong material which includes great durability and low co-efficient of friction making 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. Ultra High Molecular Weight Polyethylene provides for a range of material possible choices and properties, and these kinds of products have excellent toughness which could be worthwhile for several applications. From the food industry to automotive, the kitchen as well as the warehouse, whatever your Polyethylene needs are - High Density, Low Density or perhaps UHMW, Polyethylene is a popular option.
