Properties of plastics
1)Plastic is chemically unreactive:Plastics do not react with air and water.Due to this,plastics are resistant to corrosion.They are also often unaffected by various chemicals.The plastic containers are used to store various kinds of materials,including many chemicals.
2)Plastics are poor conductor of heat and electricity:They do not conduct heat or electricity,so they be used as insulators.
The handles of cooking utensils are made of plastic so that we can hold the hot cooking utensils safely.
Since plastics are poor conductor of electricity,they are used as electrical insulator.
Electric wires have plastic covering as insulation so as to protect us from electric current passing through them.
The handles of screw drivers used by electricians are also made of plastic because it is an electrical insulator.
3)Plastics can be moulded into different shapes
Since plastics can be easily moulded,they are used to make a large variety of articles having different shapes and sizes such as buckets,mugs,furniture,bags,sheets,bags,sheets,slippers,electrical fitting.
4)Plastics are quite cheaper and easily made
They are cheaper than metals.They are now widely used for making many of the household and industrial articles .
5)Plastics is light,strong and durable
It is because of the lower price,easy availability,lightweight,good strength,durability and corrosion resistance of plastic that the plastic container are preferred for storing food, water, milk, jams, pickles, squashes and soft drinks.
Characteristics of synthetic fibres
1)Synthetic fibres are very strong
2)Synthetic fibres are more durable:They have high resistance to wear and tear.Due to this,clothes made of synthetic fibres are very durable.
Natural fibres have low abrasion due to which the clothes made of natural fibres are not much durable.
3)Synthetic fibres absorb very little water:Clothes made of Synthetic fibres dry very quickly.
Clothes made from natural fibres do not dry quickly.
4)Synthetic fibres are wrinkle resistant:The clothes made of Synthetic fibres do not get crumpled easily during washing or wear.
Natural fibres get crumpled easily during washing and wear.
5)Synthetic fibres are light weight
6)Synthetic fibres are extremely fine:The fabric made from from synthetic fibres have a very smooth texture whereas natural fibres are not so fine.
7)Synthetic fibres are not attacked by moths
8)Synthetic fibres do not shrink
9)Synthetic fibres are less expensive and readily available.
