<\/FONT>PE<\/FONT>:<\/FONT>Polyethylene PE resin is non-toxic and odorless white particles or powder. It looks milky white and feels like wax. It is flammable with an oxygen index of only 17.4%. There is low smoke and dripping when burning, and the flame is yellow at the top and bottom. Blue, with paraffin smell; low water absorption<\/FONT><\/P>

Polyethylene PE molecules contain a small amount of double bonds and ether groups, so PE has poor weather resistance. Sun and rain will cause aging, so antioxidants need to be added. , light stabilizer to improve the thermal stability of polyethylene PE in inert gas, and the decomposition temperature can reach more than 300\u00b0C; however, when the temperature exceeds 50\u00b0C in a heated state, hot oxygen will cause a degradation reaction, so it is necessary to add anti- Oxygen is used to improve it, such as main antioxidant 1010 and auxiliary antioxidant 168; PE’s heat resistance in the air is not good, which improves with the increase of molecular weight and crystallinity; but PE’s low temperature resistance is very good, Its low-temperature embrittlement temperature is below -50\u00b0C, and can reach as low as -140\u00b0C as the molecular weight increases; PE has a high thermal conductivity. <\/FONT><\/P>
