Polypropyleenwaaks (waaks mei hege smeltpunt)
Polypropyleenwaaks (PP WAX), wittenskiplike namme fan polypropyleen mei leech molekulêr gewicht. It smeltpunt fan polypropyleenwaaks is heger (it smeltpunt is 155 ~ 160 ℃, wat mear as 30 ℃ heger is as polyethyleenwaaks), it gemiddelde molekulêre gewicht is sawat 5000 ~ 10000mw. It hat superieure smering en fersprieding.
