POLYGRAM - Desiccant masterbatches are designed to draw out moisture from plastics during melt processing. It contains a special additive that chemically binds with any moisture in the polymer melt, in a non-reversible reaction that is stable at all polymer processing temperatures. 1% of desiccant masterbatch is recommended for every 0.15% of moisture present in the polymer/compound.
Key Characteristics
Highly effective in reprocessed PE and PP
Reduces lacing and fisheyes in blown films
Eliminates porosity and blow holes caused by moisture
Reduces gels caused by moisture
Reduces production losses
Reduces the need for pre-heating
Applications
Reprocessed PP resin
Reprocessed PE resin
PP/PE with embedded moisture
To increase the LDR of filler in blown film
