Contour Stick,Essence Cushion Sunscreen Makeup SPF 50 Guangzhou Shishi Daily Chemical Co.,Ltd. , https://www.cosmeticok.com Danish company Borealis has developed a new type of polypropylene for making caps and stoppers. This polypropylene, called HG385 MO, uses the company's Controlled Crystallinity Polypropylene (CCPP) technology.
CCPP is a PP that improves the level of nuclei formation, and nucleation is desirable because it can make the hardness higher and thus may reduce part weight.
