INDUSTRY PROFILE IMPORTANCE OF subway system INDUSTRY We shall look at the prefatory data about commove plates and particularly those properties, which argon of intake in practical on the job(p) with plastics. Plastics are manmade literals. The oldest untoughened materials for producing plastics are carbonaceous materials obtained anatomy coaltar (benzene, phenol). now the majority of naked as a jaybird materials are obtained form Petro Chemical sources and they potful be economically produced in large-scale quantities. Plastics have changed our universe and day-by-day they are becoming important. They feature their winner to whole series of advantages which they have over accomplished materials much(prenominal) as 1) Light charge 2) Excellent retch ability 3) Attractive colours 4) humble postal code requirement for convention 5) beginning labour & cost of manufacture 6) Low maintenance 7) spunky qualification weight ratio 8) Corrosion resistance 9) Aesthetic without develop treatment Although plastic have strength to weight ratio, they are not as strong as metals and deform permanently chthonian load. They cannot project extremely abundantly or low temperature give care materials and new(prenominal) metals such as firm bricks. Modern invention of ice-skating skating rink or carbon-black as reinforcing fillers pave the way for making elevated strength feeling plastics and they at times replace steel. thinning MATERIALS & CHEMICALS The important raw material in manufacturing of pipes PVC resin (Poly Vinyl Chloride).

Chemicals 1) Tbls ( Tribasic check Sulphate 2) Dbls (Dibasic lead sterate 3) Ls(Lead sterate 4) Cs ( atomic derive 20 sterate 5) Sa ( Steric acid 6) Paraffin wax 7) CaCO3 (Activated calcium carbonate 8) Tritanium dioxide 9) Carbon black colour Compositions of raw materials & chemicals (As per ISI 4985—88) for the batches are as follows.
