Application Characteristics
AUSIPOL PP-30 is an Additive for PET.
AUSIPOL PP-30 Works as Regrader and repolymerizating Agent, Through the Extrusion Process. AUSIPOL PP-30 is an Additive wich when compounded into Polyesters Increases the Viscosity of the Polymers and Improves the mechanical Properties.
Addition Levels
The Range of the Dosages is between 0,10% and 1 %.
Generally, Employng virgin PET the Variations of i.v. are as follows :
- 0,3 % of AUSIPOL PP-30 increases the i.v. of 0,15 Points (i.e. from 0,75 to 0,90 dl/gr )
- 0,5 % " " " " " " 0,20 “ ( " " 0,75 to 0,95 “ )
Generally, Employing recycled PET, the Variations of the i.v. are as Follows :
- 0,3 % of AUSIPOL PP-30 Increases the i.v of 0,10 Points (i.e. from 0,70 to 0,80 dl/gr )
- 0,5 % " " " " " " " 0,15 " ( " " 0,70 to 0,85 “ )
The aforesaid must be considered Only Examples. Starting with PET at higher i.v., the Variations are more important. Employed at 0,1 %, Ausipol PP-30 acts as Processing-Aid (more regular Out-Puts, i.v. uniformed, etc.). In the PET Staple Fibers Extrusion, Thank to the long Permanence Time in the Extruder, low Dosages (i.e. 0,10 - 0,15 %) Are Enough to Obtain large i.v. Improvements.
General Properties
- AUSIPOL PP-30 is suitable for PET not transparent (Textiles, Compounds, etc.)
- AUSIPOL PP-30 must be employed as normal Master-Batch, Directly in the Hopper of the Extruder, never dryed with the PET. Starting With not dryed PET, the Addittivation must be done After the Vent (degassing Unit)
- For a complete Reaction, Please Observe these Parameters : Polyesters well dryed, Temperatures (not Below 270-280 °C), Permanence Time in the Extruder (not lower than 1'), Extruders with a good intermeshing Effect.
