Rheology Control Agent for PET
RC-610
Rheology control agent RC-610 is a kind of novel additives for PET. It can improve processing property and the rheological property of melting PET. The main functional content of it is rare earth complex, we use nanotechnology and other ingredients to produce it. The mechanism of it: By controlling the bond force between molecules of PET, it can reduce the surface viscosity of melted PET and improve the rheological property. Thus it improves the properties of final products.

Characters
• Excellent compatibility with PET resin and easy to be dispersed, has no any bad effects on heat resistant and mechanical performance.
• Improve flowability, reduce the wear of mould, increase mould filling efficiency, save power, reduce the process cost obviously.
• Improve the size precision of final products. For example, during extrusion pipe, it can prevent the draw-down and deformation of the pipe.
• In textile or fabric industry, RC-610 can reduce the temperature of PET textile yarns, and improve the spinability.
Recommended Dosage
0.5%-2%, it can mix with PET resin and molding directly, but better result can be gotten through twin screw extruding process.
Package and Storage
25kg/Bag. Placed in dry and ventilated place, avoid moisture and heat.
Example of Application
▲RC-610 can be used in PET to improve the flow ability of injection parts, then get excellent flow ability of PET, suggest to mix RC-610 with granules of PET directly, the length of injected parts will be 70% longer than the system doesn’t mix RC-610, if mix it during granulation stage, the dosage will 50% lower.
Remark: The above data are only for reference. Customer should change the formula according to actual dosage and application.
