High-density polyethylene, unlike polypropylene, cannot withstand normally required autoclaving conditions. The lack of branching is ensured by an appropriate choice of alyst (e.g., Ziegler-Natta alysts) and reaction conditions.
Solid-wall high density polyethylene pipe for municipal, industrial, agricultural and energy appliions We provide an extensive range of drainage pipes including the large diameter pipes in HDPE. We supply these to accommodate for a variety of industrial needs and requirements, so if you’re in the agricultural or energy industry you could benefit from one of our HDPE pipes!
High-density polyethylene pipe systems require fewer fittings and can be welded into seamless leak-free pipe runs, allowing for significant savings in labor and equipment. Heat-fused joints – HDPE pipe can be heat fused together to form a joint that is as strong as or stronger than the pipe itself while being virtually leak free.

High Density Polyethylene (HDPE) High density polyethylene, often abbreviated to HDPE, is a polymer whose monomer is ethylene. It is a thermoplastic with a very high strength to density ratio. HDPE is a very versatile plastic that has a wide range of appliions – from pipes to storage bottles. When compared to other plastics, the melting point of Puhui Pipe manufacturer in China
High-density polyethylene pipe (HDPE) can carry potable water, wastewater, slurries, chemicals, hazardeous wastes, and compressed gases. In fact, polyethylene pipe has a long and distinguished history of service to the gas, oil, mining and other industries. It
Polyethylene (PE) is a very robust and ductile pipe material. In its early days it was often referred to as "Alkathene", which was, in today''s parlance, MDPE or Medium Density Poly-Ethylene. Although MDPE is still used for some smaller bore pipe systems, larger bore systems are HDPE (High Density Polyethylene).
High-density polyethylene HDPE pipe is strong, robust and suitable for underground water installations. The pipe is more rigid and harder than LDPE and due to this, it is able to withstand high water pressures. With a good resistance to chemicals and weather, it is Puhui Pipe manufacturer in China
HDPE PLASTIC BOTTLES. High Density Polyethylene (HDPE) plastic bottles are a popular packaging choice for the milk and fresh juice markets. In the UK, for example, around four billion HDPE milk bottles are produced and purchased each year. HDPE provides a whole host of benefits to manufacturers, retailers and consumers.
Flexibility High density polythene is flexible. HDPE pipes can bend well outside the pipes diameter without breaking, which is a critical function, especially if serving as a surge pipe. Any breakage in a pipe can cause severe problems and issues.
HDPE high density polyethylene (PE300) has excellent impact strength, even at temperatures as low as -30ºC. Coupled with low coefficient of friction and ease of fabriion, HDPE high density polyethylene is widely used in automotive, leisure and industrial appliions and is particularly suitable for the fabriion of pipess, silos, hoppers etc.
So HMWHDPE = ” High Molecular Weight High Density Polyethylene” As you might expect, these resins are among the strongest polyethylenes pound for pound. They are so viscous that the ASTM 1238 test for melt HDPE Pipe PN16 SDR11 had to be revised when the original Mitsui 7000F came along in the late 1970’s.
Unlike the low density polyethylene, is harder, stronger and heavier, besides of being less ductile. Within the family of the polyethylene, the HDPE coexists with the UHMWPE (Ultra High Molecular Weight Polyethylene), which is used to manufacture very resistant fibres, like the ones which are used in the bulletproof jackets, and it is up to 15 times more resistant than the carbon HDPE before Puhui Pipe manufacturer in China
High-density polyethylene (HDPE) or polyethylene high-density (PEHD) is a thermoplastic polymer produced from the monomer ethylene. It is sometimes called "alkathene" or "polythene" when used for HDPE pipes. With a high strength-to-density ratio, HDPE is used in the production of plastic bottles, corrosion-resistant piping, geomeranes and Puhui Pipe manufacturer in China
High-density Polyethylene Pipe is a type of flexible plastic pipe with a high strength-to-density ratio, used in the production of plastic bottles, corrosion-resistant piping, geomeranes and Puhui Pipe manufacturer in China
High-density polyethylene (HDPE) can assist in all kinds of appliions due to its advanPE100 ISO9001eous qualities. Here are some of the most common uses of HDPE. High-density polyethylene (HDPE) is a type of plastic that one can mold into a variety of shapes after Puhui Pipe manufacturer in China
High density polyethylene takes on a new life as recycled plastic furniture as well as a host of other recycled products. The properties of HDPE make it an excellent material for piping. The Plastic Pipe Institute calls HDPE “a cost effective solution for a broad range of piping problems in municipal, industrial, marine, mining, landfill, duct and agricultural appliions.”

When your next HDPE pipe project requires a special appliion, design or configuration, HDPE, Inc. can provide a superior high-density polyethylene solution for your appliion. Below are just some of the unique appliions in which HDPE, Inc. provided expertise in design and fabriion.
HDPE pipe is a type of flexible plastic pipe used for fluid and gas transfer and is often used to replace ageing concrete or HDPE mains pipelines. Made from the thermoplastic HDPE (high-density polyethylene), its high level of impermeability and strong molecular bond make it suitable for high pressure pipelines. Puhui Pipe manufacturer in China
