Frequently Asked Questions
What is Calcium Chloride?
Calcium Chloride is a versatile calcium salt used in oilfield fluids, de-icing, dust control and concrete acceleration.
What is the CAS number and formula of Calcium Chloride?
Calcium Chloride has the CAS number 10043-52-4 and the chemical formula CaCl2.
What is Calcium Chloride used for?
Calcium Chloride is used for oilfield drilling and completion brines, plus road de-icing, dust control, concrete acceleration and desiccants.
How does Calcium Chloride work?
In oilfield use it dissolves to form a clear, solids-free brine that adds density; more broadly it is highly hygroscopic and exothermic on dissolution, which drives its de-icing and dust-control uses.
What fluid density can Calcium Chloride achieve?
Oilfield clear brines up to roughly 11.6 lb/gal (~1.4 sg); also blended with calcium bromide for higher-density systems.
Is Calcium Chloride brominated or halogen-free / is it regulatory compliant?
Supplied in oilfield and industrial grades (typically 94-96% flakes/prills). Strongly hygroscopic; keep sealed and dry. SDS on request.
What is the typical dosage or concentration of Calcium Chloride?
Concentration is set to the target brine density, de-icing rate or process requirement.
How should Calcium Chloride be stored and handled?
Keep in sealed, moisture-proof packaging in a dry area, as it is hygroscopic; keep away from acids and incompatible materials. Refer to the SDS for full handling guidance.
What packaging and minimum order quantity does Haiwang offer for Calcium Chloride?
Calcium Chloride is supplied in bulk, typically as moisture-proof 25 kg bags or 1000 kg jumbo bags on pallets. Shandong Haiwang Chemical accommodates flexible MOQs for trial and full container-load orders – contact us for current options.
Is Haiwang a manufacturer, and can it export Calcium Chloride?
Yes. Shandong Haiwang Chemical is a manufacturer (not a trader) and exports Calcium Chloride worldwide. Technical data sheets, COA and samples are available on request; contact the sales team for a quotation and lead time.
What does Calcium Chloride look like?
Calcium Chloride is supplied as white flakes, prills or granules.
What is the purity or specification of Calcium Chloride?
Typical specification: 94–96% CaCl2. A Certificate of Analysis is provided with each shipment.
Is Calcium Chloride soluble in water?
Calcium Chloride is highly soluble in water (exothermic and hygroscopic).
Does Calcium Chloride have crystallization temperature (TCT) considerations?
Yes — as a clear brine, Calcium Chloride’s true crystallization temperature depends on its concentration and density. Haiwang can recommend the right formulation, and blends where needed, to control TCT for your well conditions.
What is the shelf life of Calcium Chloride?
Kept sealed and dry, Calcium Chloride has a long shelf life of 2+ years; as it is hygroscopic, protect it from moisture.
What safety precautions are needed when handling Calcium Chloride?
Bromide and chloride brines can irritate skin and eyes — wear PPE, avoid contact, and follow the SDS.
Which synergist or co-additives are recommended with Calcium Chloride?
Calcium Chloride is typically used with calcium bromide for higher-density systems.
What are the advantages of Calcium Chloride over alternatives?
Calcium Chloride is a versatile, economical salt for brines, de-icing and dust control.
What certifications and documents can Haiwang provide for Calcium Chloride?
Shandong Haiwang Chemical can provide REACH and RoHS documentation, third-party SGS test reports, a Certificate of Analysis (COA) and Safety Data Sheet (SDS), and manufactures under an ISO 9001 quality system.
What are the lead time, shipping and payment terms for Calcium Chloride?
Samples of Calcium Chloride are usually available within a few days, and bulk lead time is typically 1–2 weeks depending on volume. Haiwang exports worldwide (FOB China ports, or CIF and other Incoterms on request) with flexible terms such as T/T or L/C — contact the sales team for a quotation, HS code and current lead time.
