Effect of Glycerine on Plastics

Glycerine is vegetable fat organic compound. It is colourless and has no smell( odorless). This experiment was to test to see the end result test the glycerine effect on the plastics.

This experiment hypothesis was that the : A biodegradable plastic can be smother depending on how much of the glycerin is is added, because plastic is made from polymers and we can whoop out some of those polymers by eating the chemical in a. On research it is said that glycerin is very soft liquid. It can be used to moisturizer by this i mean it can be used to prevent or treat skin like rough,dry etc skin. The reason why glycerin makes the plastic smoother is because the glycerin has a chain between polymers that give sit a soft surface and a soft glow. (Agriculture at work of bioplastic). The glycerine has a great function which by it feels the spaces between the polymer chains in the bioplastics thus making the plastic more stretchy ( Odec).

• Corn starch 10g
• Water 50ml
• Vinegar 5ml
• Glycerin 5ml
• Food dye ( optional )
• Beaker
• Stirrer
• Aluminum Foil
• Lighter
• Bunsen burner

Independent variable: In this experiment the independent variable is the glycerine because the more glycerin is add the smother the texture of the plastic would be and this is something that could be changed. Dependent variable: In this experiment the dependent variable is the end result which is the biodegradable plastic having a smooth texture because to point was to see the effect that glycerin would do to the plastic and that can be explained and observed when the experiment is done this experiment was to c, which let to a smooth blue plastic.

• Pour 50 ml of water to 10 ml of the cornstarch and Glass rod together by mixing.
• Add 5 ml of glycerin and make sure to add 5 ml of vinegar then mix it. Later add 3 drops of colouring to the mixture.
• Take the bunsen burner and light it up and gently put the baker to the bunsen burner to warm the mixture and stir the mixture while heating.
• After that take the baker and remove the mixture with a spoon by putting it to a baking paper. Now put it aside and let it for several days.

Were the results the same for each group? No the was not the same result for each group but very close. Other groups their plastic texture were less and more sifter The reason why is because each group that took part of the experiment did not exactly follow the procedure exactly the same way. They might have measured amount of the substances that should be mixed not exactly the same amount. As it is different maybe other groups add less glycerin ·

What variable might affect plastic? The variable that the experiment have at temperature. During the experiment while hitting the mixture of the substances, when the temperature increase the substances started to boil bubbles increasing by going up and. On the experiment the mixture should be stare while being heated If not it would have gotten the shape of becoming more solid.

According to ( Sciencelearn) the reason is because the particles are less densely pack then in the liquid state.

Conclusion: ​The purpose of this experiment was to determine if the effect that the glycerine will have in the plastic was an exceptional plastic. It was proved to be true by the observations. it was difficult to determine if the layer of paint was distributed equally across the surface of the plastic. Glycerin could be eco friendly and efficient substance because it is composed of all organic compounds and can be very easily produced.

The Product is the very future of plastics because it will change the environment since it does not require that many days to biodegrade and it will create better options for human beings to keep toxic chemicals out of our bodies. The tests results themselves prove that cornstarch plastic is exceptional and has many properties to it that could replace harmful plastics such as plastic bags. Glycerin is very simple to make and requires very little time to create. it requires at least 24 hours to dry. Glycerine will be be a good recommendation for the future because it is efficient, requires a very minimal cost and has minimal effects on the environment. Hopefully in the future the plastics will be hazardous chemical free, and that the environment that us people live in will be safe and economically friendly.

Evaluate: Since it was proven on the experiment that glycerine is the substance to gives a smooth texture to the plastic. This shows that glycerine is really great material that we can use to smoothen plastic and biodegradable plastic with. They are being improved by different type of starch in different forms with many synthetic polymers that are both non biodegradable and biodegradable to achieve great biodegradation. They have been having problems of the starch exhibit poor materials like tensile strength, yield strength etc and also poor moisture stability. Glycerin can be used to make other production. Mostly skin care production which is the reason why their or mostly used to make soap. which will have to include renewability meaning they can be capable of being renewed.

Reflection:In this experiment what went well was the end result. What i found easy was lighting a bunsen burner and knowing why the result turned into a solid at the end and. I think i didn't do much because i was not given much work. What i found hard was when we had to measure the amount of each material we had to put. Also when we had to stare the mixture while its heating, because i had to reduce the level of heat that was heating so much on the other tube before the mixture boils up and starts spilling off. I could not stare the mixture and trying to take up and down the heating temperature. What i should do next time is read the procedure carefully and also ask for some help to my friends when i need trouble.
