MCA Masterbatch for Polyamide
HFFR-MB345B
HFFR-MB345B is high content MCA compounds with PA6 carrier. It has good thermal stability and FR property. The FR mechanism is same with MCA.
Comparing the MCA powder, HFFR-MB345B has better compatibility with PA resin and better dispersity. So, it is more easy to get good FR property, better processability and dust free.
