REGRATEX MB-D 

TECHNICAL DATA SHEET

Product family: Chain Extender

Description: REGRATEX MB-D in an active masterbatch, designed for the PET reactive extrusion

and I..V. enhancement, used   to keep or to improve the viscosity and molecular weight during melt state  processing and/or further SSP.

It is suitable for   no transparent applications(Textiles, Compounds, etc.) or transparent sheets and films.

REGRATEX MB-D must be employed as normal master-batch, directly in the hopper of the  extruder, not dried with the PET  and metered by dedicated feeder.
It can be employed both on dried or  undried PET, according to application and
performance required.

At very low percentages, up to 0,2%, REGRATEX MB-D also acts as oligomers

scavenger,  recovering the original viscosity of the PET, avoiding plate-out effects on the dies and on the  polished rolls.

Usage Level: Recommended amount ranges from 0,1% to 1% according to concentration

required by user process, raw materials quality and desired I.V. to be achieved.

For Use in: PET homopolymer  or PET  copolymer

Base: Polyester
