Clarifying Agent

The most effective clarifiers are S-Orbital derivatives. Astra polymer products are a breakthrough clarifying agent technology for polypropylene (PP). Use of this additive in properly formulated and processed PP gives improved transparency, increased resin throughput, productivity gains and enhanced physical properties.

The nucleation mechanism helps to create a large number of non visible small-crystalities (< 1 micron) during the cooling of the polypropylene melt at low concentration.

Benefits :
– excellent “see-through” clarity
– good color maintenance during processing
– excellent organoleptics
– productivity improvement due to reduction of cooling time
– reduced risk of plate-out
