PPA Filler Masterbatch for plastic film
a. Efficacy: Improves Product Surface Conditions
b. Classification: Chemical Additives
c. Appearance: Granule
d. Color: White
a. Why use PPA:
PPA widens the operating parameters window and allow more control in product quality and consistencies.
b. General concept on polymer processing:
The lower the processing temperature, the better for mechanical properties.
The shorter heat transition within Extruder, the better for plastic properties to retain original specification.
Polyolefins, such as PE, PP, XLPE, PPR, PEX, POE etc.
PPA can be used in improving the performance of resins for the following types of manufacturing methods,
PPA Filler Masterbatch Benefits:
Improves product surface conditions;
Reduces surface defects such as, melt fracture, porosities, burrs, etc. Eliminates die build-up.
Improves dimension stability & controllability.
Improves color/other additives dispersion.
Reduces gel formation.
Increases Production Capability.
Reduces internal (Extruder) pressure.
Reduces the power consumption by the Extruder.
Reduces heat transition within the Extruder.
Reduces time taken for colour change.
Reduces Cost: Allows effective use of lower MFI resins, allows extrusion of temperature sensitive Resins.
Solving Common Problems:
PPA is able to resolve the following common production problems and more;
"Yellowing of White pipe/thin film after some time.
Even after purging for several hours, previous color still persists or re-appear after subsequent runs.
Internal surface of pipe or profile extrusion is rough/lines due to the nature of resin used or high percentage of recycled resins or other additives such as calcium carbonate, fiber glass or saw dust, etc.
Unable to achieve a good dispersion of color additives or other types of additives.
Problem with thin film blowing, when using a higher percentage of recycled resins.
