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.
Can plastics be sustainable?
yes.
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 injection mold therosetting plastics?
Yes, both thermoset and thermoplastic plastic be injection moulded. But different injection molding machine is needed. The technology for injection molding of thermoset is developed well now. We have rich experience in making thermoset mould, such as bakelite. if you need more information, you can contact sinomould-13@hotmail.com
