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.
What else can I help you with?
Why can't thermoset plastics change shape?
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.
Can you show thermo plastic and thermoset plastics?
no
What are the two main plastics?
thermosettings and thermoplastics. A thermoplastic can be remelted and reused, a thermoset cannot.
Why are thermoset plastic rigid?
Thermoset plastics are rigid because their molecular structure undergoes a curing process that forms strong cross-links between polymer chains. This cross-linking creates a three-dimensional network that stabilizes the material, preventing it from softening or melting when heated. Unlike thermoplastics, which can be re-melted and reshaped, the hardened structure of thermosets gives them excellent mechanical strength and thermal stability. As a result, thermoset plastics maintain their shape and rigidity under stress and elevated temperatures.
What are advantages of thermoplastic?
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.

Can you show thermo plastic and thermoset plastics?
no
What are the methods of preparation of Thermoplastics and Thermoset plastics?
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.
Two types of plastics?
thermoset which can withstand higher temperatures in comparison to the other type thermo plastics
Is urea formaldehyde thermoset or thermoplastic?
Thermosetting
What are the two main plastics?
thermosettings and thermoplastics. A thermoplastic can be remelted and reused, a thermoset cannot.
What type of plastics are used to manufacture boats?
Mostly polyester resin, but some epoxy as well. Small dinghies can be made of thermoset plastics.

Why the plastic handle used in the pressure cooker doesn't melt?
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
Is urea-formaldehyde thermoset or thermoplastic?
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.
What are advantages of thermoplastic?
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.
Is thermoset the same thing as bakelite?
Thermoset is a category of polymers that harden irreversibly when cured, while Bakelite is a specific type of thermoset resin made from phenol and formaldehyde. Bakelite was one of the first synthetic plastics and is known for its durability and electrical insulation properties. While all Bakelite is a thermoset, not all thermosets are Bakelite, as there are various other types of thermosetting polymers.
