Plastic - Wikipedia. Household items made of various types of plastics. Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient. Their plasticity makes it possible for plastics to be molded, extruded or pressed into solid objects of various shapes.

17 Οκτ 2024 · Plastic, polymeric material that has the capability of being molded or shaped. This property of plasticity, often found in combination with other special properties such as low density, low electrical conductivity, transparency, and toughness, allows plastics to be made into a great variety of products.
Plastic pollution puts animals' lives in danger and is in constant fear of extinction. Marine wildlife such as seabirds, whales, fish and turtles mistake plastic waste for prey; most then die of starvation as their stomachs become filled with plastic. They also suffer from lacerations, infections, reduced ability to swim, and internal injuries ...
Crude oil is one of the main ingredients needed to make plastic. But it’s also a fossil resource, which means there’s a limited amount of it on our planet. Happily, for one key component in plastic, called aniline, we discovered a way to create it from biomass (materials such as corn, straw and wood) instead of oil.
16 Μαΐ 2022 · Plastics are (mostly) synthetic (human-made) materials, made from polymers, which are long molecules built around chains of carbon atoms, typically with hydrogen, oxygen, sulfur, and nitrogen filling in the spaces.

Two main processes are used to produce plastics – polymerisation and polycondensation – and they both require specific catalysts. In a polymerisation reactor, monomers such as ethylene and propylene are linked together to form long polymer chains.
