Can you name 10 different facts about thermoplastics?
* acrylonite butodine styrene * acrylic * celluloid * cellulose acetate * ethylene-vinyl acetate * styrene-acrylonitrile * polyvinylidene chloride * polyvinyl chloride * polyvinyl acetate * polyurethane
What happens to glass after it is recycled?
according to an article i just read only about 24 percent of glass is recycled, it is remelted and the savings are about 20 percent from making new glass.
What is the use of poly vinyl chloride?
it is used for making toys it is an example of thermoplastics
Is acetate can be recycled?
yes it can be recycled
Can nickel be recycled?
yes it can be recycled.
Can we substitute thermosetting plastics with thermo plastics?
Thermoplastics are the only ones that can be recycled. Thermosets cannot be recycled.
What happens to thermoplastics when it is being recycled?
It gets melted and then moulded into another object
Why can thermoplastics be recycled?
Because it can be melted down , also it can be re-used as it can be reshaped.
Can thermoplastic be recycled?
Yes, thermoplastics are actually most of the plastic that we recycle.
What are the similarities between thermo plastic and thermosetting plastic?
There are a few differences between the two. Thermoplastics usually contain additives to change the properties of the material such as polypropylene. Thermosets usually contain catalysts that change the state of the material at the molecular level. The main difference between thermoplastics and thermosets is that: -Thermoplastics can be re-melted and recycled fairly easily -Thermosets typically are cured and molded into shape and are not recycled as easily
What are the advantages of thermoplastics?
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.
Two types of thermoplastic?
thermoplastics and thermosetting plastics thermoplastics go soft when exposed to heat thermosetting plastics set (harden) when exposed to heat only thermoplastics are recyclable
What kind of Plastics are Thermoplastics?
Thermoplastics are plastics that can be melted and recycled. Thermoplastics are used for many objects such as bottles, bags, records, hoses, clothes, containers, etc. There are a variety of different types thermoplastics and can have many different qualities to combat the environment. They are different from "thermosetting" plastics in this way.Thermosetting plastics are typically heated and compressed in a mold to achieve a desired shape or mixed from a resin and a hardener as used for composite material. When they are in contact with high temperatures they burn instead of melt, which is why they cannot be recycled. They are generally used for kitchen utensils like a spatula but are often used for telephones, computers etc.Thermoplastics:ABSVinylPETEPPPEHDPEPolyesterPSThermosetting plastics:Vulcanized rubberBakeliteDuroplastUrea-formaldehydeMelamine resinEpoxy resinPolyimides
Why are thermoplastics used for packaging?
Thermoplastics are used for packaging because they can be softened and reshaped as many times as the material can take. This is good, because then they can be recycled and the plastic can be used again. Thermosetting plastics however, can only be shaped once, as the polymers bond together and are inseparable. This would mean for every piece of packaging more plastic would have to be made, which would be very bad environmentally, as a lot of crude oil and other resources would need to be used up. This cannot be sustained, therefore, thermoplastics are used instead.
Are milk bottles thermoplasic or thermosetting plastic?
If it has the recycled number on the bottom (probably code 2 HDPE) it is definately thermoplastic. One characterisitics of thermoplastics is that they can melt and be remoulded whereas thermosetting plastics can not (they will char). Therefore, it logically follows that if it can be recycled it will be a thermoplastic polymer.
Pvc is a thermoplastic give the main advantage of thermoplastics?
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 is meant by polythene is a thermo plastic?
Thermoplastics become less viscous or melt when heated. such plastics may be recycled that means may be moulded into another shape on melting. Thermoset plastics do not - for instance melamine.
