PVC S57 is a free flowing vinyl chloride homopolymer resin having low molecular weight. It is manufactured by suspension polymerization.
PVC S60 is a medium-low molecular weight PVC homopolymer of particular interest in rigid applications and has established a deserved reputation for low gels and exceptional early color heat stability. These properties, along with outstanding lot to lot uniformity have made F616K an industry-wide standard for rigid formulations.
PVC S65 is a medium-low molecular weight PVC homopolymer designed primarily for rigid extrusion applications, but it is also suitable for many flexible applications. This products has high bulk density and excellent dry flow characteristics, making it desirable for dry blending applications where uniform feed rate to an extruder is important.
PVC S67 is a medium molecular weight PVC homopolymer suitable for both rigid extrusion applications and many flexible applications. This products has good bulk density and excellent dry flow characteristics, making it desirable for dry blending applications where uniform feed rate to an extruder is important.
PVC S70 is especially suited for processing from powder blends due to its ability to rapidly absorb plasticizers regardless of molecular weight. In addition, this products offers:
* Excellent Electrical Properties
* Low Contamination
* Low Gel Content
* Excellent Heat Stability
* High Finished products Physical Properties
* Lot To Lot Uniformity
