honestly no one knnows it just comes from the earths core.
thats not what i heard:
polythylene was created by accident by a German chemist Hans Von Pechmann in
1898 while he was heating diazomethane. when his coleages saw a white, waxy substance. whisch was then name polymethylene, it was changed after to polythylene.
What else can I help you with?
Does polythene paper cause global warming?
Polythene paper does not directly cause global warming. However, the production of polythene, which is a type of plastic, releases greenhouse gases that contribute to global warming when not disposed of properly. It is important to manage and recycle polythene products to reduce their environmental impact.
What charge develops on rubbing plastic straw with polythene?
When you rub a plastic straw with polythene, the plastic straw becomes negatively charged due to the transfer of electrons between the materials. Electrons are transferred from the polythene to the plastic straw, leaving the straw with a negative charge.
Rub one refill pen refill with polythene and place it carefully in a glass tumbler rub the other refill with polythene and bring it closer to the first refill placed in the glass what do you observe?
When you bring the polythene-rubbed refill pen closer to the other refill pen in the glass, you may observe them repelling each other. This is due to the buildup of static electricity on the pens from the rubbing of polythene, causing them to have like charges and repel each other.
Why is sodium packed in polythene?
Sodium is packed in polythene to prevent it from reacting with air or moisture, which could lead to degradation and reduced effectiveness of the substance. The polythene helps to create a barrier that keeps the sodium away from these elements, thus ensuring its stability and purity until it is ready for use.
What bag is the strongest biodegradble bags or a polythene bag?
I believe biodegradable bags are the strongest because they are made to withstand pressure, weather changes, or just about any force. The strength and quality of these bags are made to last a lifetime.

When was Polythene - album - created?
Polythene - album - was created in 1996.
Is polystyrene biodegradable?
Polystyrene is NOT biodegradable
Why does polythene have a negative charge with a cloth?
When polythene is rubbed with a cloth, electrons are transferred from the cloth to the polythene, causing the polythene to become negatively charged. This transfer of electrons creates an imbalance of charges between the two materials, resulting in the polythene having a negative charge.
What is rigid polystyrene?
Rigid polystyrene is a hard plastic Rigid polystyrene is a hard plastic
