Manufactured by a variety of manufacturers under several tradenames: Polyboard®, Polymar®, Hostalen®, Polystone®, Hitec® HDPE, Corrtec®, Sanalite®, UltraEthylux®, Polycarve®, and Densetec®.
For great abrasion resistance, very low density, and FDA/NSF compliance, Polyethylene products are an excellent choice.
Self-lubricating and a low coefficient of friction
Very High Chemical Resistance
Low Specific Gravity (Floats in Water)
Can be Heat Welded or RF Welded
High Impact Strength and Energy Absorption
Exceptional Low Temperature – Brittle at -110° F
Does not chemically bond
HDPE/LDPE are ITAR compliant, and HDPE/LDPE are RoHS compliant
Main Differences:
HDPE – Harder material, little to no flex, better tensile strength LDPE – Softer, very flexible, lower tensile strength
Applications – HDPE:
Cutting Board and Food Preparation Surfaces
FDA, USDA, NSF Compliant Machined Parts
Heat Formed and Vacuum Formed Parts
Dasher Board For Ice Rinks – Impact Parts
Welded Tanks, Hoppers, Silo Linings and Slide Chutes
Chemical and Structural Tanks and Covers
Food Processing Equipment, Valve, and Pump Components
Other applications include cement molds, body boards, transfer boards, death beds, mortician boards, cooler storage boards, spine board, tank liners, wear guides, and many, many more.HDPE is used in thousands of applications, from interiors of freezers, bed liners for trucks to personal protection gear.
HDPE is available in stock in natural (milky white) and black. Other colors are available with minimum runs.

Playground HDPE is UV stabilized for outdoor applications that is available in a variety of colors.
These properties are for evaluation purposes only. This information is not to be construed as a warranty, guarantee or assurance that you may achieve the same results. Materials made from different resin types, manufacturing techniques and manufacturers will react differently. The information should be used to compare against other materials only, and each user should make his own tests to determine suitability. No warranty as to this materials suitability are either expressed nor implied.
Next time you are cutting vegetables on your cutting board, the material most likely to be used is Polyethylene. Because it is stain, moisture and odor resistant, Polyethylene is a perfect choice. Other cutting boards made out of wood are more susceptible to bacteria and odors because they lack the properties that Polyethylene sheets offer, such as its chemical resistance and FDA approval for food contact. Polyethylene is a very durable and lightweight material that comes in many forms and is a great for a wide variety of applications.
NSF Approved Cutting Boards
The HDPE is available in .500″ thick in several FDA / NSF approved colors, and is great for use in kitchens where cross contamination is a problem.
The Ultimate Cutting Board
Polyethylene has many names. The most common are HDPE, LDPE, and UHMW. The difference has to with the molecular weight and branching which is when a monomer or atom is replaced by a longer chain of polymers (a long repeating chain of atoms). High Density is commonly used for milk jugs and food containers. Low Density is commonly used for bottles and plastic bags. UHMW, which has higher molecular weight (2-6 million) allows for an even transfer over the length of material which makes it stronger and able to be used for bearing applications due to its great wear resistance. Commonly used in the food and dairy industry, UHMW is a great replacement for other materials and solution to many problems. All of these polymers are derived from the same family but all have certain properties that make them a little different. HDPE provides great chemical resistance, with high impact strength and great energy absorption. LDPE has most of the same properties as High Density but is not as dense at 9.15, opposed to HDPE which is 9.34. It also has a lower tensile strength and easier formability.
UHMW is a strong material that has great durability and low co-efficient making it an ideal for sliding applications. Polyethylene offers a wide range of material choices and properties and has great durability that can be suitable for a number of applications. From the food industry to automotive, the kitchen or the warehouse, whatever your Polyethylene needs are; High Density, Low Density or UHMW, Polyethylene is a great choice.
