PVC SG-5, Xinjiang Tianye
SG-5 is the most widely used suspension PVC grade and the only one that works in both rigid and flexible formulations. Its viscosity number of 107–118 ml/g places it in the middle of the GB/T 5761 scale: the resin still takes up plasticiser, yet already gives a rigid enough part without one. That is why it accounts for most of our volume and why we carry it from three mills at once.
Applications
- Pressure and non-pressure pipe
- Window and door profile
- Fittings and couplings
- Cable compound
- Hose and tubing
- Film and sheet

Storage and transport
Store in a dry, cool place in the closed original packaging, protected from moisture and sunlight. Provide ventilation and avoid dust accumulation. Resin that has taken up moisture cakes and doses poorly. Not classified as dangerous goods; carried by any covered transport.
