I have seen in many research articles, Researchers have prepared a composite like the following combinations:
Polymer (70%), Filler-1 (30%) & Filler-2 (2 phr)
Now, I would like to get clear about the "phr" and how to convert the 2 phr into weight percentage. Batch size is 2kg.
Thanks!
Hello dear, the mean of Phr is part by 100 of rubber, but wt% is a general term and it can be employed for any composition. Another hand, phr is employed in blends or composites of rubber. Best regards

your batch will have 2 kg of total mass. Assume you prepare x kg of the mixture; then the following composition arrives:
polymer 70%.x
fliier 1 30%.x
filler 2: 2%.x
total:102%.x = 2 kg from that: x=~1,96 kg. and then:
polymer: =1,3725 kg; filler 1: 0,5882 kg and filler 2=0,0392 kg; total:2,00kg
