HJ325MO is a polypropylene homopolymer intended for injection moulding. Its very high melt flow makes it especially suitable for thin-wall packaging and products with long flow length. is designed for high-speed injection moulding and contains nucleating and antistatic additives. The additives are optimized to provide reduced tendency for mould plate-out.
This polymer is a CR (controlled rheology) grade with narrow molecular weight distribution giving low warpage. Components moulded from this grade show good ejectability and combine good stiffness with good transparency and gloss, good antistatic properties and good impact strength at ambient temperatures.
Applications
Thin wall containers
Square containers
Rectangular and flat products, like lids and trays
Caps and closures
Special features
Good stiffness
Good impact strength
Excellent antistatic properties
