A thermoset plastic is a nonmeltable plastic that was made by melting down a powder and when that happens, all the little plastic molecules theoretically combine to make one giant molecule. This is why you cant remlt it, all that would happen if you tried to melt the thermoset plastic, is the plastic would burn away. Think of it like this: think of roaps, and that each rope is a molecule, when you tie the ropes together you can pull them apart, think of that al melting normal plastic together, in that it still has a melting point where the molecules come apart. Now if you were to weave each strand together that makes up the rope, you wouldn't be able to pull it apart. Teoretically that's what happens in thermoset plastic, all the molecule come together and form a giant one. So that means we can think of the hood of a big rig to be one giant molecule.

What are thermoplastics and thermosets plastics?

Thermoplastics soften or melt when heated. Thermoset plastics harden or set when heated.


Why can't thermoset plastics change shape?

Because of cross linking in the chains. This happens when heat is applied to the plastic. Once this has taken place thermoset plastics can not change shape or change to a thermosoft plastic.


What are the characteristics 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


What are the different types of plastics?

Types of plastic - polyethylene (HDPE or LDPE) found in plastic bags and shampoo bottles - polystyrene (PS) found in computer cases - polypropylene (PP) found in dishwasher safe containers - polyethylene terephthalate (PET) found in soda bottles - polyvinyl chloride (PVC) More generally speaking in engineering, plastics are divided into thermoplastic plastics and thermoset plastics These are based on their properties upon reheating after the plastic is molded. Thermoplastic plastics when heated will melt whereas thermoset plastics will not melt but only burn This is due to the way the branches of polymers coordinate. Thermoplastic plastics governed by largely van der waals forces. Thermoset plastics are crosslinked by covalent bonds


What plastics are thermosetting?

Phenolic, epoxy, amino and unsaturated polyesters are thermosetting plastics. Due to their property of becoming set solids while processing due to chemical changes, they are named as thermoset plastics.


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.


What are the 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.


What happens when you heat thermoset?

Thermoset plastics are intially heat-treated to cure them and set them in their final form. Subsequent heating doesn't do much of anything unless it's so hot they actually burn.


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.
