- From wiki: Polyethylene or polythene is the most common plastic in use today. It is a linear, man-made, addition, homo-polymer, primarily used for packaging. As of 2017, over 100 million tonnes of polyethylene resins are being produced annually, accounting for 34% of the total plastics market. Wikipedia
Formula: (C2H4)n
Melting point: 115-135 °C (239-275 °F; 388-408 K)
Density: 0.88-0.96 g/cm3
Magnetic susceptibility (χ): −9.67×10−6 (HDPE, SI, 22°C)
Abbreviations: PE
Log P: 1.02620
Ethylene can exist in various types based on whether side groups exist and how long they are. High-density polyethylene HDPE has no branching, linear low-density polyethylene LLDPE has small branching, and low-density polyethylene LDPE has large branching. Applications just as parts, packaging, bottles.
Short and efficient thank you for really good help in my polymers study for college
Glad to help!
solid work
💪🏻💪🏻💪🏻
Well done in time frame.
nice polymer, good chemical compatibility.
Ya, such a versatile material!
How does hdpe mfg affect environment in close proximity???
Nice but I still get one tapped in with .366 geksa
