High Density Polyethylene Plastic
High density polyethylene hdpe is manufactured at low temperatures and pressures using ziegler natta and metallocene catalysts or activated chromium oxide known as a phillips catalyst.
High density polyethylene plastic. As one of the most versatile plastic materials around hdpe plastic is used in a wide variety of applications including plastic bottles milk jugs shampoo bottles bleach bottles cutting boards and piping. High density polyethylene is a plastic made from ethane. Pex is a medium to high density polyethylene containing cross link bonds introduced into the polymer structure changing the thermoplastic into a thermoset. Hdpe is commonly recycled and has the number 2 as its resin identification code.
Your strongest everyday plastic high density polyethylene hdpe sheet is extremely strong against impact abrasion resistant and exhibits a low coefficient of friction. But high density polyethylene or hdpe plastic has been courting my favor recently. High density polyethylene or polyethylene high density is a thermoplastic polymer produced from the monomer ethylene. High density polyethylene hdpe sheet this sheet can be heat formed shaped and welded to fabricate ducts hoods and much more.
It is used to make bottles jugs and other containers used as short term storage for milk detergent and bleach. Hdpe is easy to fabricate and weld using thermoplastic welding equipment making it an excellent choice for fabricated water tanks and chemical tanks. Hdpe can be translucent or opaque and the opaque varieties are stronger. The material is also moisture stain and odor resistant and is fda approved for use in the food processing industry mainly for cutting boards.
High density poly ethylene hdpe is a thermoplastic polymer made from petroleum. What is high density polyethylene. With a high strength to density ratio hdpe is used in the production of plastic bottles corrosion resistant piping geomembranes and plastic lumber. It is sometimes called alkathene or polythene when used for hdpe pipes.
The high temperature properties of the polymer are improved its flow is reduced and its chemical resistance is enhanced. High density polyethylene hdpe is a cost effective thermoplastic with linear structure and no or low degree of branching. It is coded as a number 2 plastic for recycling. The material cannot be cemented but it is easily welded with a plastic welder.
High density polyethylene hdpe is a strong durable lightweight and chemically resistant plastic material popular for a variety of applications. Not only is it one of the most versatile of plastics used in everything from hard hats to house wraps it s also widely recycled in both its rigid form e g containers and flexible form e g bags. Known for its outstanding tensile strength and large strength to density ratio hdpe plastic has a high impact resistance and melting point.
