Strontium carbonate is used in the manufacture of color TV cathode-ray tubes, electromagnets, strontium ferrite, pyrotechnics, fluorescent glass, flares, etc.. It is also the raw material for producing other strontium salts. Used as the basic powder for the production of special PTC thermistor elements (switch start, demagnetization, current limiting protection, constant temperature heating, etc.)

Gypsum is a soft sulfate mineral consisting of calcium sulfate dihydrate (CaSO4:2H20). It is widely used as a fertilization, mold, sculpture and plaster material.

Calcium ash powder (the main component is calcium hydroxide, which is a refined product of lime) and bicarbonate powder (the main component is calcium carbonate, which is a calcium carbonate powder directly ground from calcium carbonate) generally do not cause the phenomenon of blistering of putty powder after use.

We have developed a series of fluorinated polyimide monomers and other hexafluoroacetone derivatives.
