There are almost countless numbers of things made from thermosetting plastics. Just a single example are the plastic forks, knives and spoons that we consider as "disposable" or "single use" utensils.
no
No. Although there may be some very rare exceptions, plastics are made from oil. Those which are made from vegetable sources may be sustainable in very small quantities but as soon as food crops are replaced for bio oil-production on a large scale, they cease to be sustainable.
Thermoset plastics cannot change shape because they undergo a irreversible chemical reaction during the curing process. This reaction, known as crosslinking, creates strong bonds between the polymer chains, making the material rigid and inflexible. Once set, thermoset plastics cannot be melted or reshaped like thermoplastics.
thermosettings and thermoplastics. A thermoplastic can be remelted and reused, a thermoset cannot.
Thermoplastic plastics melt when heated and therefore can be easily molded and recycled. In comparison, Thermoset plastics utilize a chemical reaction to cure and irreversibly set.
no
Mostly polyester resin, but some epoxy as well. Small dinghies can be made of thermoset plastics.

Thermosetting
Thermoplastic operations involve blowing a heated plastic into a mold. The end product is hollow. Thermoset plastics are sheets of plastic heated and place over two parts of a mold that come together. The end result is not hollow.

Urea-formaldehyde is a thermoset plastic. Once it is cured, it undergoes a chemical reaction that permanently sets its shape, making it hard and durable. Thermoset plastics cannot be reshaped or melted once they are formed.

there are two types of Plastics. the Thermoset and the Thermoplast. these Plastics all Melt, but @ different temperatures. the Thermoplast melts easily and can be recycled, while the thermoset has a property that makes it difficult to melt @ the temperature of the cooker that is being heated.this therefore explains why the Plastice does not melt because its thermoset Plastic and It has a higher temperature
Ideally all of it. All plastic should be recycled where possible, unless it's bio-degradable. Also, all plastic Items should be made from recyclable plastics. There are very few items these days that need to be made using thermoset plastics.
