POSS® Flow Aids - Case Study
Helicopter Vortex Tubes - Nanoreinforced® COC replaces glass reinforced PP
Problem:
Customer needed to mold a highly complex, thin walled part. Available resin systems presented these problems:
- flow problems either with highly filled polyolefins or high temperature polymers (e.g. COC, PEEK...)
- mold abrasion with highly filled polyolefins (e.g. PP)
- material degradation at high processing temperature
POSS® Flow Aids can solve these problems, and provide additional improvements
The graph in the sidebar to the right shows that, depending on the type of POSS® Flow Aids used, the melt flow can be increased by as much as 65% to 148% with only a 5 wt% incorperation of POSS® Flow Aids into Cyclic Olefin Copolymer (COC). This can lead to reductions in cycle time and higher throughput.
In addition, POSS® Flow Aids act as a mold release agent in COC. When combined with the other properties, this allows for the rapid injecting of very thin walled parts without having to sacrifice in strength or asthetics. End-parts perform better, are of lower weight, and have a better surface finish.
And unlike other flow aids, POSS® Flow Aids are themally stable up to 400º and will not degrade during the processing of high temperature polymers.
