Introduction Of Polyethylene In Diapers

Polyethylene in diapers, referred to as PE, is a thermoplastic resin obtained by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefins. Polyethylene in diapers, odorless, non-toxic, feels like wax, has excellent low temperature resistance (the lowest operating temperature can reach -100~-70 degrees Celsius), good chemical stability, and can withstand most acid and alkali erosion (not resistant to oxidizing acids). Insoluble in common solvents at room temperature, low water absorption, excellent electrical insulation.

Polyethylene in diapers has the following excellent properties:

1. High impact resistance

The impact resistance and impact absorption of ultra-high molecular weight polyethylene rank first among plastics, and it is difficult to crack it no matter it is a strong external impact or internal pressure fluctuations. Its impact strength is 10 times that of nylon 66, 20 times that of polyvinyl chloride, and 4 times that of polyethylene. Especially in low temperature environment, its impact strength reaches a higher value instead. This flexibility of ultra-high molecular weight polyethylene provides a safe and reliable guarantee for the delivery system.

2. High wear resistance

Among many pipeline materials, the friction coefficient of ultra-high molecular weight polyethylene is the smallest, and the ultra-high molecular chain is particularly long, so that the wear resistance of modified ultra-high molecular weight polyethylene pipes is better than that of steel pipes and stainless steel pipes when transporting various slurries. 4-7 times higher, about 10 times higher than PVC pipes and polyethylene pipes, greatly improving the service life of the pipes.

3. Corrosion resistance

UHMWPE is a saturated molecular group structure, so its chemical stability is extremely high, and it can resist the erosion of various highly corrosive media (acid, alkali, salt) and organic solvents within a certain temperature and concentration range.

4. Wide temperature adaptability

It can work at a temperature of -269 degrees Celsius to 80 degrees Celsius for a long time.
