Applicant's summary and conclusion
- Conclusions:
- From the obtained experimental data according to CIPAC method MT 59 and MT 170, it can
be concluded that, after 5 minutes of shaking, the particle size distribution of BETAMETHYLEPOXY
is: 11.89% of the sample presents a particle size higher than 0.710 mm
(710 μm), 24.98% of the sample presents a particle size higher than 0.500 mm (500 μm),
37.70% of the sample presents a particle size higher than 0.355 mm (355 μm), 62.62% of the
sample presents a particle size higher than 0.250 mm (250 μm), 98.00% of the sample
presents a particle size higher than 0.125 mm (125 μm), 99.20% of the sample presents a
particle size higher than 0.075 mm (75 μm) and 0.76% of the sample was found under 0.045
mm (45 μm).
