One version is made from injection-molded plastic, while the other is HDPE from an extrusion line. Furthermore, researchers are now developing a cutting board made from HDPE plastic waste as a more environmentally friendly option. These cutting boards use calcium carbonate for filler, and glass fiber as reinforcement. [6]
HDPE is known for its high strength-to-density ratio. [4] The density of HDPE ranges from 930 to 970 kg/m 3. [5] Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength (38 MPa versus 21 MPa) than LDPE.

Plastic cutting boards. Research published last year in the journal Environmental Science & Technology found that using a plastic cutting board can create up to 7,680 flecks of plastic, which can ...
Polypropylene can also be made into disposable bottles to contain liquid, powdered, or similar consumer products, although HDPE and polyethylene terephthalate are commonly also used to make bottles. Plastic pails, car batteries, wastebaskets, pharmacy prescription bottles, cooler containers, dishes and pitchers are often made of polypropylene ...
“Wooden boards are considered to be a porous material, so cutting things like meat, poultry and fish on them may make it harder to fully clean and disinfect them afterward, increasing the risk ...
Medium-density polyethylene (MDPE) is a type of polyethylene defined by a density range of 0.926–0.940 g/cm 3. [1] It is less dense than HDPE, which is more common.. MDPE can be produced by chromium/silica catalysts, Ziegler-Natta catalysts or metallocene catalysts.
