What is the difference between mdpe and hdpe

It has high crystallinity and thus does not dissolve easily. It is resistant to dissolving at room temperature. Because of its characteristics, HDPE is used for manufacturing packaging products, detergents, garbage containers, etc. HDPE has great inertness so it is easy to assemble and has excellent strength when used in manufacturing water and pressure pipe systems.

MDPE has excellent chemical resistance and is very stable at room temperature. It does not dissolve at room temperature. MDPE has very good drop resistance and shock resistance. It is less sensitive and has a higher stress-cracking resistance than HDPE. It is used for varied purposes, but some primary usages are for gas pipes manufacturing, carrier bags, packaging film, etc. HDPE has the density 0. However, the stress cracking resistance is higher. This material is used mainly in the production of gas pipes, sacks, fittings, packaging films, carrier bags, etc.

These polymers form when ethylene molecules undergo polymerization under different reaction conditions. Available here 2. Available here. With a mind rooted firmly to basic principals of chemistry and passion for ever evolving field of industrial chemistry, she is keenly interested to be a true companion for those who seek knowledge in the subject of chemistry.

HDPE is high-density polyethylene, a polymer material that forms from the polymerization of ethylene monomers.

How can PE pipe be connected to other pipe materials? Products: Valves Are PE valves available? Can PE pipe be connected to metal valves? Products: Traceability How can I verify the origin of the pipe and fittings? Quick access. Last update Thursday 31 May MDPE is also a thermoplastic that is prepared by applying low pressure with the help of using transition metal catalysts like metallocene catalysts.

It is comparatively less opaque when compared with HDPE. It is extremely crack resistant but less rigid and hard. It is less expensive and easily affordable. It is flexible and thus used in manufacturing bags. This is stronger but not tough enough. This is produced on a smaller scale when compared with other density polyethylene.

It is both stiff as well as flexible at the same time. It has less chemical resistance and rigid. It is used in the manufacture of pipes due to its favorable mechanical qualities like high ductility, impact strength, and also low friction. It has favorable properties that make it suitable for a lot of commercial applications.

It is resistant to both acid and base and also resistant to oxidants and reducing agents. There is a high demand in the market for this thermoplastic due to its good quality, affordable price, and also sue to its favorable mechanical properties.

Gas pipes, water, waste, and sewage are carried through the pipes of MDPE polymers. It is also used in agriculture due to its flexibility and easiness.
