Physical and chemical properties
It is a white powder with a characteristic odor, stable nature and easy to react with oxidants. The pH is 10.5 (concentration of 10 g/l at 20 ° C), melting point is 270.4 ° C, and decomposition point is 277-284 ° C. Soluble in acidic water, slightly soluble in methanol and water.
Excellent grade technical indicators:
Appearance: White powder
Particle size: 99% ≤ 45μ
Decomposition point: 276-286 ° C
Loss on drying (120 ° C): ≤ 1.5%
Calcium content: 16.6 ~ 17.5
Calcium acetylacetonate content: ≤98%
Usage and Dosage: Add calcium acetylacetonate when the product is synthesized at high temperature. The dosage is 1-2.5% of the product (due to the different quality standards of the raw materials produced by each manufacturer, the dosage should be based on the test)
Uses: This product can be used as an additive, including halogenated polymers, especially used in PVC plastics as light stabilizers, heat stabilizers and antioxidants. It can greatly extend the service life of plastic products, so that plastic products can maintain their original color and transparency for a long time. It is a non-toxic new type of plastic stabilizer, which is superior to the organic tin series stabilizer. It meets the requirements of the RoSH environmental protection directive and is an environmentally friendly product that replaces lead-containing additives. Calcium acetylacetonate is widely used in various industries, especially in the fine chemicals industry, and is a cost-effective product among heat stabilizers.
