Next occasion you are slicing veggies against your chopping board, take the opportunity and check out it, the material most likely to be used as a High Density Polyethylene Cutting Board - Sheets cutting board is Polyethylene. Given it is generally FDA and National Sanitation Foundation approved in addition to stain, moisture and odor resistant, Polyethylene is the perfect choice for cutting boards.
Alternative cutting boards made from wood are vulnerable to bacteria and long term odors because they lack the properties that Polyethylene sheets offer, including its non porous surface, chemical resistance and approval for food contact. Polyethylene is undoubtedly a durable and lighter weight material that comes in a good many forms and is ideal for a wide variety of applications. There are several kinds of Polyethylene commercially available. The commonest are HDPE (High Density Polyethylene), LD Polyethylene, and UHMW (Ultra High Molecular Weight Polyethylene). The the main 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 (an excessively long repeating chain of atoms).

The High Density Polyethylene happens to be used for milk jugs and food containers. Low Density is commonly used for milky colored bottles as well as plastic 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, making it useful for bearing products for its great wear resistance. Commonly used in the food processing and dairy industry, Ultra High Molecular Weight is a great replacement for numerous industrial materials along with a fantastic resolution to many wear issues. Every one of those polymers are made from the same polyolefin plastic materials family, but they all have certain properties that make them 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 however it's not as dense at 9.15, as an alternative to HDPE which is 9.34, and it is a softer material ( flexible coffee can lids). Additionally, it provides a lower tensile strength along with much better, simpler heat processing.
UHMW is definitely a strong material that possesses great durability and low co-efficient of friction rendering it an ideal for sliding applications. Dupont makes the 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 wide range of material solutions and properties, and these types of products include outstanding strength that can be best with numerous applications. From the food industry to automotive, your kitchen or the warehouse, whatever your Polyethylene needs are - High Density, Low Density or even UHMW, Polyethylene is a popular decision.
