| Process Aids for PVC |  |
Advantages
The advantages of our Process Aids are:
• Accelerated fusion speed
• Increased productivity and decreasing processing temperature
• Better dispersion of additives
• More homogeneous PVC
• Lower possibility of pinhole, flow marks and melt fracture
• Improving vacuum formability and foam extrudability
• Better surface gloss and excellent surface quality
• Improving tensile properties, impact efficiency, weldline strength,
etc.
