RMA-57	Is a low molecular weight PVC Resin which offers excellent flow properties, clarity, and low gels Field Of Use: Recommended for rigid calendered sheeting, blow molded bottles, and injection molded items such as PVC pipe fittings
RMA-62	Is a low molecular weight PVC Resin. It offers good melt flow properties, low gel count, and excellent heat stability Field Of Use: Recommended for flexible, semi-rigid, extrusion and calendering applications
RMA-66	Is a medium molecular weight PVC Resin. Field Of Use: Recommended for general purpose extrusion and calendered film and sheeting
RMA-73	Is high molecular weight modified PVC Resin offering superior melt flow characteristics, low gel count, rapid plasticizer absorption and excellent heat stability. Fields Of Use: Recommended for calendered film and sheet, wire and cable coating, and flexible extrusion.
