1889. Eastman Kodak successfully filed a patent for the celluloid film. [6] 1890s. Galalith, a plastic derived from casein developed by Wilhelm Krische and Adolph Spitteler. [7] 1890s. Auguste Trillat discovered the means to insolubilize casein by immersion in formaldehyde, producing material marketed as galalith.
Infobox references. Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene. Polypropylene belongs to the group of polyolefins and is partially crystalline and non-polar.
In the European Union (EU), too, heavy investments have been made in the plastics industry, which employs over 1.6 million people with a turnover of more than 360 billion euros per year. In China in 2016 there were over 15,000 plastic manufacturing companies, generating more than US$366 billion in revenue.
J. Paul Hogan. John Paul Hogan (August 7, 1919 [1] – February 19, 2012) [2][3] was an American research chemist. Along with Robert Banks, he discovered methods of producing polypropylene and high-density polyethylene. [1]
The plastic kits and covers are mostly made of synthetic polymers like polythene, and tires are manufactured from polybutadienes. [1] However, due to the environmental issues created by these synthetic polymers which are mostly non-biodegradable and often synthesized from petroleum, alternatives like bioplastics are also being considered. They ...
Biodegradable plastic. Biodegradable plastics are plastics that can be decomposed by the action of living organisms, usually microbes, into water, carbon dioxide, and biomass. [1] Biodegradable plastics are commonly produced with renewable raw materials, micro-organisms, petrochemicals, or combinations of all three. [2]
A thermoplastic, or thermosoftening plastic, is any plastic polymer material that becomes pliable or moldable at a certain elevated temperature and solidifies upon cooling. [1][2] Most thermoplastics have a high molecular weight. The polymer chains associate by intermolecular forces, which weaken rapidly with increased temperature, yielding a ...
Plastic recycling is the processing of plastic waste into other products. [ 1 ][ 2 ][ 3 ] Recycling can reduce dependence on landfill, conserve resources and protect the environment from plastic pollution and greenhouse gas emissions. [ 4 ][ 5 ] Recycling rates lag behind those of other recoverable materials, such as aluminium, glass and paper.
