Thermal Crack Wax, derived from high - temperature cracking of hydrocarbons like polyethylene or polypropylene resins, is a specialty wax with unique properties. It typically has a relatively high molecular weight, presenting as a solid at room temperature. This wax shows excellent high - temperature stability, remaining stable under harsh processing conditions. 

In the plastics industry, Thermal Crack Wax serves as an outstanding external lubricant in PVC products such as profiles, pipes, and fittings. It offers good late - period lubricating ability, which not only gives products a more glossy appearance but also reduces processing torque. In masterbatch production, it functions as an efficient dispersant, ensuring better dispersion of inorganic components and pigments for a more appealing product look. It's also an excellent external lubricant in PVC stabilizers, especially ca - zn stabilizers. When combined with suitable internal lubricants, it can significantly enhance the overall performance of stabilizers.
