美国Mayaterials代理，美国Mayaterials销售。
In 2009 Mayaterials Inc. formed a joint venture with Ceres Group, "EXIMO Hard Coatings" to commercialize coatings primarily for one specific application, semi-permanent mold release.
Recently, Mayaterials Inc. back integrated its IP such that silica products as a whole have become a major focus. Our patented silica extraction technology allows us to make very low cost, high purity, surface property tailored precipitated and colloidal silicas at large scales opens up opportunities including its use in the production of:
-
food grade silica
-
high quality, low cost, vacuum insulation panels,
-
solar grade Si (99.9999 % purities),
-
fiber glass
-
optical grade silica (99.999 % purities,
-
fillers and extender for polymer composites, and
-
desiccants.
