Polyolefins (LDPE, HDPE, PP) are a major type of thermoplastic. [10] LDPE is widely used for manufacturing various containers, dispensing bottles, wash bottles, tubing, plastic parts for computer components, and various molded laboratory equipment. Its most common use is in plastic bags. Other products made from it include:
Nalgene is a brand of plastic products developed originally for laboratory use, including items such as jars, bottles, test tubes, and Petri dishes, that were shatterproof and lighter than glass. The properties of plastic products make them suitable for work with many substances in various temperature ranges.
Most wash bottles are made up of polyethylene, which is a flexible solvent-resistant petroleum-based plastic. Most bottles contain an internal dip tube allowing upright use. Wash bottles may be filled with a range of common laboratory solvents and reagents, according to the work to be undertaken.
LLDPE has penetrated almost all traditional markets for polyethylene; it is used for plastic bags and sheets (where it allows using lower thickness than comparable LDPE), plastic wrap, stretch wrap, pouches, toys, covers, lids, pipes, buckets and containers, covering of cables, geomembranes, [1] and mainly flexible tubing. In 2013, the world ...
Starch is most commonly used as a biodegradable additive for both low-density polyethylene (LDPE) and high-density polyethylene (HDPE). [8] Since polyethylene is used for a wide range of uses, from plastic bags to plastic water bottles to outdoor furniture, large amounts of PE plastic is thrown away each year, and determining ways to increase ...
Key Takeaways from Chlorinated Polyethylene Market Study: The market is set to expand from USD 889.3 million in 2024 to USD 1,780.7 million by 2034, with a CAGR of 7.2%. The construction sector remains the largest end-use industry, accounting for a substantial share of demand. Asia-Pacific dominates the market, driven by strong growth in China ...
There are a wide range of applications for linear alpha olefins. The lower carbon numbers, 1-butene, 1-hexene and 1-octene are overwhelmingly used as comonomer in production of polyethylene. High-density polyethylene and linear low-density polyethylene use approximately 2-4% and 8-10% of comonomers, respectively.
Polyethylene was first synthesized by the German chemist Hans von Pechmann, who prepared it by accident in 1898 while investigating diazomethane. [12] [a] [13] [b] When his colleagues Eugen Bamberger and Friedrich Tschirner characterized the white, waxy substance that he had created, they recognized that it contained long −CH 2 − chains and termed it polymethylene.
