Description of key information

Additional information

The tap density of the test item was determined according to CIPAC MT 169. The sample mass for the sieve test was calculated and the machine sieving was carried out using the following test sieves 4, 2, 1 mm, 500, 250, 125, 63 µm.

The particle size distribution of P-PP was found to be [ 63 µm, 2000µm], details below:

63 µm 14.43g (14.3%);

125 µm 9.98g (9.9%);

250 µm 16.50g (16.4%);

500 µm 27.54g (27.3%);

1000 µm 26.10g (25.9%);

2000 µm 4.38g (4.3%);

4000 µm 0.06g (0.1%);
