1. Characteristics of (polypropylene)
Physical properties
Pure is translucent ivory white, waxy is non-toxic and odorless , odorless milky white highly crystalline polymer with the lightest density among general plastics. The molding shrinkage rate % is particularly stable to water, and the water absorption rate in water is . The surface of the product has good gloss and is easy to color.
Mechanical properties
(Polypropylene) has high crystallinity, regular structure, and good mechanical properties. Its strength, hardness, and elasticity are relatively good, but its impact strength is poor at room temperature and low temperature. When the molecular weight increases, the impact strength also increases, but the molding performance becomes worse. (Polypropylene) The most outstanding property is its resistance to bending fatigue. The dry friction coefficient is similar to nylon, but not as good as nylon under lubricating oil.
