PP is commonly used for packaging applications such as bottles, containers, and bags. It offers good barrier properties, moisture resistance, and durability. PP is used in the manufacturing of various automotive parts, including bumpers, interior trim, and dashboard components. It provides excellent impact resistance and can withstand high temperatures.
PP material is polypropylene, polypropylene is non-toxic, odorless, tasteless milky white high crystallization polymer, density is only 0.90 --" 0.91g /cm3, is one of the lightest varieties of all plastics. It is particularly stable to water, water absorption rate is only 0. 01%, molecular weight of about 8,000-150000. Formability is good, but because of the shrinkage rate is large (1%~2.5%). Thick wall products are easy to sag, for some parts with higher dimensional accuracy, it is difficult to meet the requirements, the product surface luster is good.
Polypropylene, a kind of plastic, it is a kind of high density, no side chain, high crystallization will be linear polymer, with excellent comprehensive properties. Common products: basin, bucket, furniture, film, woven bag, bottle caps, car bumper, etc.
