What is polyesterine?
It appears there may be a typo in your question. If you meant "polyester," it is a synthetic fabric made from polymer fibers that is often used in clothing, upholstery, and other textiles. If you meant "polystyrene," it is a synthetic polymer commonly used in packaging materials, disposable containers, insulation, and other applications.
What are the key differences between natural amber and synthetic amber?
Natural amber is formed from fossilized tree resin over millions of years, while synthetic amber is created in a laboratory using artificial resins. Natural amber often contains inclusions like insects or plant matter, while synthetic amber is usually free of inclusions. Additionally, natural amber tends to have a higher value and is considered more valuable than synthetic amber in the jewelry market.
What are disadvantages of synthetic rubber?
Some disadvantages of synthetic rubber include a higher cost compared to natural rubber, potential environmental impact during production, and the inability to biodegrade as easily as natural rubber. Additionally, some synthetic rubbers may not have the same elasticity or durability as natural rubber.
Is aluminium natural or syntheti?
Aluminium is an element, it is not synthetic.
What is a large covalently-bonded molecule that has a repeated structural unit?
A polymer is a large covalently bonded molecule that has a repeated structural unit. Examples of polymers include proteins, DNA, and synthetic plastics like polyethylene.
Is polyvinyl chloride synthetic or natural?
It is a synthetic addition polymer.
Is spider webs natural polymers or a synthetic polymer?
is a spider web a polymer
What are natural and synthetic polymers?
A natural polymer would be rubber which is obtained from nature. A synthetic polymer would be polybutadiene which behaves like rubber.
Is basketball polymer natural or synthetic?
neither
Is rayon a synthetic polymer?
Not truly. Neither is it a natural fibre. It is manufactured from cellulose, which is a naturally occurring polymer. It's regarded as "semi-synthetic", or "artificial".
Is an eraser a synthetic or natural polymer?
different erasers are different materials so both. some are made from rubber that comes from trees and others are made syntheticly
What is acrylic paint Mae of?
a natural or synthetic pigment in an acrylic polymer emulsion
Is natural rubber is a protein?
No nitrile rubber is a synthetic rubber polymer
How is the polymer classified?
For example thermoplastic and thermosetting polymers, natural and synthetic polymers.
Is starch a synthetic or natural polymer?
natural, starches are a form of sugar, potatos have a form of starch. I'm sure there are also some synthetic ones as well.
Which polymer exists in both synthetic and natural forms?
Polyethylene is a polymer that exists in both synthetic forms, widely used in plastic manufacturing, and natural forms, found in plants and trees as a waxy coating.
Why are synthetic materials made?
Because you can design a synthetic polymer to exactly meet your needs. You can modify a natural polymer sometimes if it's not what you need, but at that point is it really a "natural" polymer? Take cellulose--a perfectly serviceable natural polymer, they build millions of homes every year out of it. But what if you need a polymer you can see through? Cellulose won't work for you there unless you dissolve it in acetic acid (cellulose acetate) or nitric acid (cellulose nitrate). By the time you're done, you have a polymer that's no longer really "natural."
