HDPE Overview
What is HDPE?
HDPE (High Density Polyethylene) is a type of plastic that is strong and durable, resistant to many chemicals, and has a high strength-to-density ratio. HDPE is used as a lumber replacement in certain applications such as outdoor furniture, decks, and docks. It is also used in automotive, agricultural, and medical device components, as well as for industrial drums and containers, packaging, and consumer products.
HDPE is a strong industrial grade plastic known for its long-term durability and high impact strength. HDPE also has strong resistances to a variety of chemicals, different types of weather, and abrasion.
What are HDPE Plastics used for?
HDPE is a versatile plastic that tolerates a wide array of substances and environments and is used in many applications across a wide range of industries. In marine applications, HDPE is used for boating seats, floors, cabinetry, and countertops. Along with general consumer goods such as folding chairs and tables, HDPE is used to make bottle caps, food containers, and laundry detergent bottles. HDPE's chemical resistance allows it to serve as the base for chemical and corrosion resistant piping and tank linings. HDPE replaces lumber in the construction of outdoor furniture and patio decks, and has applications in the automotive industry as well as the agriculture and medical industries.
What does HDPE plastic mean?
HDPE is an acronym for High-Density PolyEthylene, a versatile thermoplastic made from petroleum. HDPE is a durable, lightweight, and mechanically strong plastic with chemical and corrosion resistances that is widely used for many applications across industries worldwide.
What are the disadvantages of HDPE?
The disadvantages of HDPE include susceptibility to UV degradation, high flammability, and sensitivity to stress cracking. These downsides are offset by HDPE's benefits, including its high strength-to-density ratio, durability, low moisture absorption, and corrosion resistance.
