In thermoplastic polyurethanes , phase separation dose not exist but in thermoplastic elastomer polyurethanes phase separation has occured .

The main difference between polyurethane and thermoplastic polyurethane is that PU is chemical bonded while TPU is heat bonded. TPU tends to feel softer and more like fabric than PU which has a more plastic feel.


thermoplastic resin doesn't need cross-linking agent in application because it dries only by solvent evaporation. Thermoset polyurethane using cross-linking agent such as melamine resins and then stove in certain temperature usually over 100 deg Celsius in order to cure in application

There isn't too much of a difference between elastomers and plastics. The only real difference between them is how far you can stretch them. Other than that they are really similar.



Thermoplastic and thermoset materials both fall under the broad category of Polymers. The biggest difference between a thermoplastic and thermoset is that a thermoplastic can be recycled. Whereas a thermoset irreversibly cure. Thermoplastic: PE, PP, PVC. Thermoset: Bakelite, Epoxy.


the difference between thermosetting plastic and thermoplastic is thermosetting plastic is a plastic that can irreversibly cures the cure may be through heat) and thermoplastic is a type of plastic that can be vacuum formed.hope this helps you :)


A thermoplastic can be remelted and reused, thermosetting plastics cannot.


You have stated the difference in your question - one is essentially oil, the other is water.


thermosetting plastic becomes hard when heated and deteriorates by excessive cross linking and thermoplastic becomes soft and can be moulded into any shape.


A Thermoplastic can be reshaped when reheated, like bowls wheras and thermosetting plastic are bonded permanently when heated and set hard as they cool like plugs etc


The major difference difference arises on the basis of the forces... In Elastomers, the polymer chains are held together by weakest intermolecular forces while in fibers, the intermolecular forces are strong like hydrogen bonding.

ACT has thermoplastic insulated wires. AC is old MC is the modern cable.


Polyurethane isn't epoxy, but they're both resins. They're also both reaction copolymers--you get either one through a chemical reaction between two components. The difference is, epoxy contains epoxide and polyamine; polyurethane contains a complex alcohol (either a "diol" or a "polyol") plus an isocyanate.


Polyvinyl chloride, (IUPAC Poly(chloroethanediyl)) commonly abbreviated PVC, is the third most widely used thermoplastic polymer after polyethylene and polypropylene. Chlorinated polyvinyl chloride (CPVC) is a thermoplastic produced by chlorination of polyvinyl chloride


THHN is a heat resistant thermoplastic insulated conductor, usually a single conductor. Romex is a brand name for a nonmetallic sheathed cable.


The terms are used to categorise cable insulation according to its properties, such as its operating temperature, rather than the ingredients from which it is are made.These terms are now used by the IEE Wiring Regulations to describe insulation formerly described, for example, as 'pvc' (a 'thermoplastic' material) or rubber ( a 'thermosetting' material).


I would use a primer in between.


The difference in properties:Thermoplastics lack cross-links, which makes them weaker than thermosetting plastics and thus, easier to melt and bend.Thermosetting plastics have cross-links, which makes them stronger and harder to melt and bend/ break.


A Thermoplastic can be reshaped when reheated, like bowls wheras and thermosetting plastic are bonded permanently when heated and set hard as they cool like plugs etchope this helps you :)A Thermoplastic can be re-shaped when re-heated, like bowls where as thermosetting plastics are bonded permanently when heated and set hard as they cool. Examples include telephone cases, transferred teeth etc.1. A thermoplatic material is softened by heating but the process is reversible.2. In the case of thermosetting materials the process is not reversible.thermosetting plastic can be reused by melting but thermoplastic can not


A thermoset is a material that cures or sets into a given shape, generally through the application of heat. A cured, thermoset material will not remelt or otherwise regain the processibility it had before being cured. Curing changes the material forever. A thermoplastic material softens (becomes pliable and plastic) when heated, but it does not cure or set. It can be reheated to be reformed.


Thermoplastic structures only have weak forces/bonds between molecules. Thermosetting molecules however have strong inter-linked cross links and strong bonds between their molecules. This would effect their melting point etc.


The Young modulus and the yield strength are very different for these types of polyurethane,


thermo setting plastic sets really fast and thermoplastices are used in tarps and stuff and are usually nylon. to do this they pull them out into long strands then weave them. this makes them flexible. one of them is flamable but i cant remember which
