The " Plastic Effect "- Know Your Plastic

Friends with my third post again here i am...

after reading my last two posts i hope you people would have been started saving papers...Ahhhaaann !!

Hey i am just kidding guys... :)

so do you know what is steaming tonight in my mind????  Guesses???  Yeahh??...okkhhaayy..

It is nothing but the material we people are using since decades...so what is that??

My friends that is Plastic...which is used on large scale in Domestic,Commercial and Industrial purposes...
so what say...shouldn't we take a sight on plastic and its "Plastic Effects"

Do you really think,you know about this plastic completely?
I don't think so !!        okkkhhaayyy....okkkhhaayy....

Let's check your Plastic knowledge then...

Q:   What Is Plastic???

A:   " A material made from petroleum capable of being molded, extruded or cast into various shapes "

 A plastic material is any of a wide range of synthetic or semi-synthetic organic solids that are modifiable. Plastics are typically organic polymers of high molecular mass, but they often contain other substances. They are usually synthetic, most commonly derived from petrochemicals, but many are partially natural.

                                                      Did You Know   ? ? ? ? ?

 The word plastic is derived from the Greek " Plastikos " meaning capable of being      shaped or molded, from " Plastos " meaning  molded

Q : Categories of Plastic???

A : i would like to tell you,your Plastic has these several categorizations

you must be aware of them...so..here we go...

other used forms are....

• Polyester (PES) – Fibers, textiles.
• Polyethylene terephthalate (PET) – Carbonated drinks bottles, peanut butter jars, plastic film, microwavable packaging.
• Polyethylene (PE) – Wide range of inexpensive uses including supermarket bags, plastic bottles.
• High-density polyethylene (HDPE) – Detergent bottles, milk jugs, and molded plastic cases.
• Polyvinyl chloride (PVC) – Plumbing pipes and guttering, shower curtains, window frames, flooring.
• Polyvinylidene chloride (PVDC) (Saran) – Food packaging.
• Low-density polyethylene (LDPE) – Outdoor furniture, siding, floor tiles, shower curtains, clamshell packaging.
• Polypropylene (PP) – Bottle caps, drinking straws, yogurt containers, appliances, car fenders (bumpers), plastic pressure pipe systems.
• Polystyrene (PS) – Packaging foam/"peanuts", food containers, plastic tableware, disposable cups, plates, cutlery, CD and cassette boxes.
• High impact polystyrene (HIPS) -: Refrigerator liners, food packaging, vending cups.
• Polyamides (PA) (Nylons) – Fibers, toothbrush bristles, tubing, fishing line, low strength machine parts: under-the-hood car engine parts or gun frames.
• Acrylonitrile butadiene styrene (ABS) – Electronic equipment cases (e.g., computer monitors, printers, keyboards), drainage pipe.
• Polyethylene/Acrylonitrile Butadiene Styrene (PE/ABS) – A slippery blend of PE and ABS used in low-duty dry bearings.
• Polycarbonate (PC) – Compact discs, eyeglasses, riot shields, security windows, traffic lights, lenses.
• Polycarbonate/Acrylonitrile Butadiene Styrene (PC/ABS) – A blend of PC and ABS that creates a stronger plastic. Used in car interior and exterior parts, and mobile phone bodies.
• Polyurethanes (PU) – Cushioning foams, thermal insulation foams, surface coatings, printing rollers (Currently 6th or 7th most commonly used plastic material, for instance the most commonly used plastic in cars)

in the above picture it is advised to avoid  (1)PET, (3) PVC, (6)PS, (7)Others .


Q:   Properties of Plastic?

A:   The properties of plastics are defined chiefly by the organic chemistry of the polymer such as hardness, density, and resistance to heat, organic solvents, oxidation, and ionizing radiation. In particular, most plastics will melt upon heating to a few hundred degrees celsius. While plastics can be made electrically conductive, with the conductivity of up to 80 ks/cm in stretch-oriented poly acetylene, they are still no match for most metals like copper which have conductivities of several hundreds ks/cm.

Some facts :

1. Early plastics were bio-derived materials such as egg and blood proteins, which are organic polymers. Treated cattle horns were used as windows for lanterns in the Middle Ages.
2. In the 1800's the development of plastics accelerated with Charles Goodyear's discovery of vulcanization as a route to thermoset materials derived from natural rubber. Many storied materials were reported as industrial chemistry was developed in the 1800's.
3. The plastic material, parkesine, was patented by Alexander Park es, In Birmingham, UK in 1856. It was unveiled at the 1862 Great International Exhibition in London.
4. The first so called plastic based on a synthetic polymer was made from phenol and formaldehyde, with the first viable and cheap synthesis methods invented in 1907, by Leo Hendrik Baekeland, a Belgian-born American living in New York state
5. Plastics were the material pegged to change the world; and they have had an amazing impact. But for all the technology and convenience borne from the polymer family, untold perils are becoming realized as well.
   
6. The average American produces a half-pound of plastic waste every day; while around the world, 300 million tons of the exceedingly durable material are produced each year.
7. Electrical and Electronic equipment and Motor Vehicle markets together accounted for 58 % of plastics demand in 2003.
8. 200 million tonnes of plastic manufactured annually around world And consumption rate is 61.5 pounds of plastic per person per year.
9. With the growth in consumption, plastic production in India is likely to grow by 60 % to touch 12.75 million tonne by 2012, according to a industry body.

so that's all guyz.... I'll be back soon with the Effects of plastic...Do read it and get some time to comment on it...your suggestions are most welcome......

Keep tracking...
Take care of You and Our Earth...
