DMA 650 

DMA 650 provides homogeneous melt flow at different production rates in addition to providing high impact resistance and mechanical properties in PVC applications. Enhanced powder properties bring advantages in packaging and handling. Thanks to its special design, DMA 650, with its easy-flow, low dust and odor characteristics, can be used  with automatic handling and feeding systems, for quicker and safer working operations. Semfa Group DMA 650 enables manufacturers to produce high quality complex PVC products even at high production rates. Having long-lasting UV resistance and excellent color stability and durability, DMA 650 ensures that PVC products can retain original appearance during long-term outdoor exposures and under adverse weathering conditions. In addition to its unaccompanied use in formulations, DMA 650 can offer more economical solution to our producers, thanks to the many years of experience of Semfa Group has in PVC stabilizers area, by means of reducing the use of Impact Modifier (DMA 650) in its formulation.

• Improved impact strength
• Lowered plate-out
• Procurement of the product from one supplier instead of two.
• Cost saving regarding storage, dosage at hot mixer
