UHMW stands for Ultra High Molecular Weight. Now it depends what the monomer is. UHMWPE would be thermoplastic not thermoset. But other UHMW polymers can be thermoset. It depends.
Thermosetting
Thermoset
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.
no
The answer is thermoset :)
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.
i think its a thermoplastic I'm not too shore but when its heated it melts so yeah i guess so :)
thermoplastic
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
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.
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.
