Wood-plastic composite. Wood–plastic composites (WPCs) are composite materials made of wood fiber/wood flour and thermoplastic(s) such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), or polylactic acid (PLA).
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.

HDPE is impervious to most acids, and toxic chemicals clean from them more easily. Some plastic pallets can collapse from plastic creep if used to store heavy loads for long periods. Plastic pallets cannot easily be repaired, and can be ten times as expensive as hardwood, [ 11 ] so they are often used by logistics service providers who can ...
In the last six months average lumber prices have ranged from $475 to $625 per thousand board feet, about one-third the peak in 2021. Trump has threatened to add 25% tariffs on goods from Mexico ...
Lumber’s price drop has been particularly dramatic in just the last 90 days in the futures market, with contract prices for July falling 28% to $466 per thousand board feet (futures prices are ...
Plastic lumber is composed of virgin or waste plastics including HDPE, PVC, PP, ABS, PS and PLA.The powder or pellets are mixed to a dough-like consistency at roughly 400 °F (204 °C) and then extruded or molded to the desired shape.

Ultra-high-molecular-weight polyethylene (UHMWPE, UHMW) is a subset of the thermoplastic polyethylene.Also known as high-modulus polyethylene (HMPE), it has extremely long chains, with a molecular mass usually between 3.5 and 7.5 million amu. [1]
