| Message: | SC 90A is based on Fischer-Tropsch synthetic wax produced by domestic coal-to-oil manufacturers as raw materials. It is prepared through pretreatment, short-path distillation, hydrorefining and other processes. It has high melting point, low oil content, small penetration, hard and wear-resistant. It is almost free of impurities such as sulfur, nitrogen and aromatic hydrocarbons, and is mainly used in hot melt adhesives, PVC heat stabilizers, inks, coatings, plastic processing lubricants, rubber and plastic processing, masterbatch dispersants and other fields.
