Functions and Dosage of various PVC Lubricants-2 3. Fischer Tropsch WaxFischer Tropsch synthetic wax has a linear structure which gives high-temperature resistance, lower viscosity and softening points between 65-105°C. It increases the fusion time and stability of PVC while decreasing the fusion torque required for the processing of PVC. Its linear structure provides an excellent metal release effect and reducing the form…
