What is the difference between thermoplastic polyurethane and thermoplastic elastomer?
In thermoplastic polyurethanes , phase separation dose not exist but in thermoplastic elastomer polyurethanes phase separation has occured .
What is the difference between a polyurethane PU coating and a thermoplastic polyurethane TPU coating?
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
what is the difference between the strenght of thermoplastic rubber and latex
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.
it's just the same thing
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 :)
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 remelted and reused, thermosetting plastics cannot.
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
You have stated the difference in your question - one is essentially oil, the other is water.
Rigid PUR foam is stiff as a board, and is sometimes used as a board. Flexible foam is soft and squishy.
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.
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
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.
polyethylene Average: 1.42 polyurethane Average: 0.25
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).
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.
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 hope 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… Read More
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.
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.
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
THHN is a heat resistant thermoplastic insulated conductor, usually a single conductor. Romex is a brand name for a nonmetallic sheathed cable, it has multiple conductors inside, the insulated ones are insulated with THHN insulation.
I would use a primer in between.
The basic difference between Thermosetting and thermplastic material is that when we heat the materials the thermosetting material gets hardened the first time and if we again heat it, just burns without deforming while the thermoplastic materials on heating loses its toughness and come into plastic state where it can be moulded to any shape of desired nature. The thermosetting materials are hard and have atomic structure that bound each other strongely and on heating… Read More
1 coat epoxy = 60 coats of polyurethane paint - less finish appearance. requires more time to cure. Requires mixing of activator/catalyst with paint just before application, any not used after mixing must be thrown away. Requires min 50 Fahrenheit condition for application. Less UV tolerant. Hard. Polyurethane - good glossy finish. Expensive. No mixing of activator/catalyst with paint needed. Any temperature conditions possible to apply. Less curing time.
Southwire, a manufacturer of this type of cable defines ACT as a multiple conductor thermoplastic insulated cable with steel spiralled interlocking armour. The armour has the appearance of flexible conduit. AC cable is also known as BX cable. Common insulation materials thermoset and thermoplastic as used in AC cable. Type AC cable have different identifiers and insulation type. Type ACTHH has 194 degree (90 degree Celsius) thermoplastic insulation. Type ACTH has 167 degree (75 degree… Read More
Urethane rubber is actually not rubber. It is known as urethane elastomer and is cheaper than Silicone rubber. However, it does not last a long and requires the application of a release agent before every casting. It is cheaper than silicone rubber and has a higher tear strength.
Did you know all plastics fall into only 2 categories when it comes to their reaction to heating? These 2 categories are called Thermoplastic and Thermosetting. Thermoplastic materials become soft when they are heated and solid when cooled to room temperature. This is similar to heating and cooling wax. Thermoplastics are materials such as acrylics, cellulosics, polyamide, polystyrene, polyethylene, fluoroplastics, polyvinyls, polycarbonate, and polysulfone. Thermosetting materials cannot be reheated and softened again. Once these are… Read More
Plastics are developed for various purposes, and often blended together to achieve what the company is looking for in performance. In the case of polyurethane, there are versions that are soft foam for mattresses, rigid foams, other in between, and also rigid.
cuz it has a lot of air particles in between which allows the sound to travel slower.
This is sourced from <a href="http://www.spray-lining.com">Spray-Lining Source</a> Polyurea Polyurea is typically hard and not very flexible. It resists abrasion and tearing due to high tensile strength. However, its harder surface allows cargo to slip because typically it is smoother than a softer polyurethane application. Polyureas are more expensive than polyurethanes and require specialized application tools and protective equipment to spray. Polyurethane Polyurethane can be flexible and much softer than polyureas. Like anything there is a… Read More
Thermoplastic materials can be heated and cooled numerous times from a rigid to a flexible form (i.e., acrylic, polycarbonate sheet, etc) while thermosetting plastics (i.e., polyester and epoxy resins) change from a liquid form (most common) to a one-time (non-remeltable) solid form.
Polyurethane. I used a clear gloss polyurethane spray can that I bought from Home Depot, and it worked pretty well. I put about 4 coats on it, and sanded in between each coat with a 1000 grit sand paper, except on the last coat.
How can you tell the difference between water based and oil base polyurethane once it is on the floor?
Generally a colour difference is the thing to be looking for. An oil based poly will generally have a browning effect on the timber that increases with age. A waterbase poly will generally give very little if any tonal change. Bear in mind that newer waterbased polys are 100% polyurethane products that will exhibit very litlle tonal change in their lifetime, but earlier products (and some "new") are co-polymers that sometimes seemed to bleach or… Read More
The main difference between them is that thermoset is irreversible and thermoplastic is reversible. Another difference is that when thermoset when heated does not go soft whereas thermoplastic does. A thermo-plastic is mechanically bonded and as such will melt when exposed to heat. The amount of heat varies with the polymer involved. Thermoplastics can be recycled and are polymers such as P.T.F.E, P.E.T, C.O.C, H.D.P.E, L.D.P.E, acrylic, acetate and thousands more. A thermo-setting polymer does… Read More

LSZH or LSHF cables are not flame retardant. Some cables use polyurethane jackets that while emitting low levels of nasties, actually burn at a fast rate dripping burning plastic onto whatever is below. If flame retardant cables are required, look for FRNC (Flame Retardant Non-Corrosive).
ThermoplastIc materials (such as polyethylene, nylon, etc ) are melt-processable, meaning that they can be heated to a melt (liquid) phase, forced into a mold, and then cooled to form a pre-determined shape. Typical processes include injection molding, compression molding, and blow molding. Thermoplastic materials can, many times, be potentially ground up and re-processed many times as there is no chemical reaction that occurs. Thermoset materials (such as epoxy, and some polyesters), on the other… Read More
