Now we improved the quality of our liquid crystal monomers:
The purity of LC single is increased from 99.5% to 99.9%,
the single impurity is controlled by 0.05%,
and the resistivity is improved to 1*1011 above.
PDLC mixture (LC + polymer + additives)
The purity of LC single is increased from 99.5% to 99.9%,
the single impurity is controlled by 0.05%,
and the resistivity is improved to 1*1011 above.
Our Korean sales agency use our liquid crystals to make PDLC mixtures in South Korea,
it well used to make PDLC film and switchable film directly.
