Walendziewski and Steininger reported the thermal degradation of polyethylene in the temperature range 370–450°C. In the case of thermal degradation of polyethylene, an increase in degradation temperature led to an increase of gas and liquid products, but a decrease of residue (boiling point > 360°C).
Polythene, also known as polyethylene, is a thermoplastic, not a thermosetting plastic. Thermoplastics can be reheated and reshaped multiple times without affecting their properties, while thermosetting plastics undergo a chemical change during heating and cannot be reshaped once set.
it attrarts paper :P
The polythene becomes negatively charged.
Rubbing a piece of cloth with a polythene rod transfers electrons from one material to the other due to friction. This causes the cloth to become negatively charged and the polythene rod to become positively charged, leading to the attraction between them due to opposite charges.
Polythene.
The polymer "polythene".
Polyethene (polythene, polyethylene) is a chemical product.
Polythene - album - was created in 1996.
When polythene is exposed to heat, it softens and can ultimately melt. This is because the heat increases the kinetic energy of the polymer chains in polythene, allowing them to move more freely and weakening the overall structure of the material. Continued exposure to high heat can further break down the polymer chains and eventually lead to decomposition.
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.
hazards of polythene bags
When a steel spoon is rubbed with polythene, the transfer of electrons can occur due to friction between the two materials. This results in the spoon becoming negatively charged, while the polythene becomes positively charged. This static electricity interaction causes the two materials to be attracted to each other.
