Dongteng special wax characteristics

  • Using petroleum wax as the basic raw material, paraffin wax that adapts to special properties and specific site requirements is prepared through special processing or blending of added components.

  • The basic composition of special waxes is a saturated hydrocarbon structure, and the content of aromatic hydrocarbons, nitrogen, oxygen, sulfur and other substances is approximately zero.

  • Special waxes are mineral oils that have been specially deeply refined.Due to this super refining depth, it is difficult to implement heavy fractions in the actual manufacturing process, so the molecular weight of special waxes is usually in the range of 250 to 450, and it does not corrode fiber textiles.
