HDPE as a cutting board
On your next occasion you're the one chopping vegetables and fruits against your slicing board, take the time and check out it, the material most likely to be used as a High Density Polyethylene Cutting Board Material - Sheets cutting board is Polyethylene. Because it is generally FDA and NSF approved together with stain, moisture and odor resistant, Polyethylene is the perfect choice for chopping boards.
Different cutting boards made of wood are at risk to bacteria and long term odors because they lack the sought afterproperties that Polyethylene sheets offer, such as its non permeable surface, chemical substance resistance and approval for food contact. The Polyethylene is certainly a durable and light-weight material that comes in several forms and is perfect for a wide selection of applications. You can find several kinds of Polyethylene commercially available. The most widespread are HDPE (High Density Polyethylene), Low Density Polyethylene, and UHMW (Ultra High Molecular Weight Polyethylene). The key difference has to do with the molecular weight and branching; which happens when a monomer or atom is replaced by a longer chain of polymers (a very long repeating chain of atoms).

High Density Polyethylene is frequently used for gallon sized milk jugs and common food containers. Low Density is often used for milky colored bottles or perhaps plastic sandwich 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, which make it useful with regard to bearing products due to its great wear resistance. Commonly used in the food processing and dairy industry, Ultra High Molecular Weight Polyethylene is an excellent replacement for many other industrial materials together with wonderful means to many wear issues. Most of these polymers are created from the same polyolefin plastic materials family, but all have certain properties that make them just a little different. HDPE provides great chemical resistance, with higher 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, whereas HDPE which happens to be 9.34, and it's a softer material ( the one gallon coffee can lids). Also, it has a lower tensile strength plus superior, simpler heat processing.
UHMW can be described as strong material with great durability and low co-efficient of friction which makes it an ideal for sliding applications. One of the only 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 provides a wide range of material alternatives and properties, and all these materials include extraordinary toughness which could be just the thing for a number of applications. From the food industry to automotive, your kitchen or the warehouse, whatever your Polyethylene needs are - High Density, Low Denseness as well as UHMW, Polyethylene is a fantastic choice.
