Thermosetting and thermoplastic
Two common plastic groups used for heat and moulding plastics are thermoplastics, which can be melted and remoulded multiple times through heating and cooling processes, and thermosetting plastics, which undergo a chemical change during moulding and cannot be remelted or reshaped after the initial moulding process.
A list of board certified plastic surgeons can be obtained by contacting The American Society of Plastic Surgeons and The American Board of Plastic Surgery. Both organization have websites with tools for searching for certified members. These groups are the most prominent sources of plastic surgery certification information.
Molecules containing a large number of hydroxyl groups are known as polyols or polyalcohols. They are commonly found in natural compounds such as sugars and polyols serve as important building blocks in the chemical industry to produce polymers, plastics, and other materials.
Plastic name badges or name tags are used for new groups or clubs so everyone can get to know everybody else's name. It is a simple way to help people introduce themselves.

The essential reaction is between phosgene and bisphenol.
Bisphenol A, commonly abbreviated as BPA, is an organic compound with two phenol functional groups. It is a difunctional building block of several important plastics and plastic additives.
Yes,Plastics can be classified by chemical structure, namely the molecular units that make up the polymer's backbone and side chains. Some important groups in these classifications are the acrylics, polyesters, silicones, polyurethanes, and halogenated plastics. Plastics can also be classified by the chemical process used in their synthesis, such as condensation, polyaddition, and cross-linking.
Because paper and plastic are recycled through completely different processes. As a matter of fact many plastics are recycled in different ways.

It's when light breaks up the chemical (covalent) bonds in the plastic's molecules, causing the plastic to break up into (hopefully) fluid substances, which either evaporate, sink into the ground and flow away, or are more easy to dispose of. There are some metallic ions and organic groups which are good at absorbing light, so these can be used to help get light into the target bonds. However these additives may lead to the products of the plastics' degradation being toxic.

The red color comes from the large amounts of Iron Oxide (or rust) in the clay. Clay is generally made up of groups of minerals that include the kaolin, smectite, illite, and chlorite groups. Also see the related link.
