EverStar Group delivers factory-direct Liquid Formic Acid (methanoic acid, CAS 64-18-6) with over 13 years of proven manufacturing expertise. Our progressed chemical generation office keeps up over 5,000 tons of on-site stock, guaranteeing quick shipment and steady supply over four concentration grades: 85%, 90%, 94%, and 99%. Supported by EU REACH compliance and in-house R&D research facility, we give custom fitted details for calfskin tanning, silage conservation, chemical amalgamation, and mechanical descaling. With chloride substance ≤0.005% and press ≤5 ppm, our high-purity formic corrosive meets strict execution guidelines for B2B clients in development, horticulture, pharmaceuticals, and water treatment businesses around the world.

Formic acid (HCOOH) is the simplest carboxylic acid in organic chemistry. It appears as a colorless, fuming liquid with a characteristic pungent odor.
Why choose it over mineral acids?
Industrial buyers prefer formic acid for processes requiring efficient pH adjustment, reduced environmental footprint, and cost-effective dosing in large-scale operations.

Four Concentration Grades for Diverse Applications
We supply formic corrosive at four standard concentrations to coordinate your correct mechanical needs:
85% – Standard Mechanical Grade
Ideal for calfskin tanning (pickling), material coloring (pH alteration), and mechanical descaling. This review accounts for the larger part of worldwide utilization and offers the best adjust between execution and cost.
90% – Nourish Additive Grade
Preferred for silage added substance applications utilizing the AIV strategy. It quickly drops pH underneath 4.0 to repress clostridia and pathogenic microscopic organisms, guaranteeing wholesome judgment in high-moisture capacity conditions.
94% – Concentrated Chemical Union Grade
Used for fabricating formate esters, formamide, and pharmaceutical intermediates. Higher concentration diminishes water substance, making it perfect for responses delicate to moisture.
99% – High-Purity Claim to fame Grade
The purest frame for strength chemical amalgamation and rising applications such as coordinate formic corrosive fuel cells (DFAFC) and fluid natural hydrogen carriers (LOHC).

In calfskin tanning, formic corrosive serves as a rapid-penetration specialist for deliming and pickling. Its moo instability guarantees uniform pH alteration all through the cover up, coming about in prevalent fiber quality. Material processors depend on it for pH control amid coloring and wrapping up stages.
As a potent preservative (E236), Liquid Formic Acid suppresses pathogenic bacteria like Salmonella and E. coli in animal feed and silage. It maintains nutritional value even under challenging high-moisture storage conditions, making it the preferred choice for modern livestock operations.
Formic corrosive acts as a flexible decreasing operator in the Leuckart response and serves as a formyl bunch benefactor in the generation of Dynamic Pharmaceutical Fixings (APIs) and elastic chemicals. Its tall reactivity quickens throughput in high-pressure reactor environments.
Unlike hydrochloric or sulfuric corrosive, formic corrosive offers biodegradable descaling for boilers, warm exchangers, and mechanical gear. It expels calcium carbonate stores productively without taking off destructive buildups.

Q: What is the commonplace lead time for bulk orders?
A: Standard lead time is 7-14 days for all four concentration grades. For critical orders or custom definitions, if it's not too much trouble contact our deals group at info@cneverstar.com for assisted scheduling.
Q: How ought to I store formic corrosive safely?
A: Store in a cool, dry, well-ventilated range absent from coordinate daylight and warm sources. Since the solidifying point is 8.4°C, temperature-controlled capacity is prescribed in colder climates. Utilize corrosion-resistant holders made of polyethylene or stainless steel.
Q: Can you give specialized back for particular applications?
A: Yes. Our experienced group of chemical engineers offers full lifecycle support—from item discussion and detailing optimization to after-sales specialized help. We give nitty gritty application rules and measurement proposals for your industry.
Q: Is your formic corrosive compliant with universal regulations?
A: Completely. Our generation office is EU REACH enlisted and ISO compliant. We give total documentation counting Certificate of Examination (COA), Fabric Security Information Sheet (MSDS), and compliance certificates upon request.
Q: What is your least arrange amount (MOQ)?
A: We offer adaptable MOQ alternatives to suit both trial orders and large-scale generation needs. Whether you require a single 25kg drum or numerous ISO tank holders, we can fulfill your requirements.
Q: Do you offer custom concentration grades?
A: Yes. Our in-house R&D research facility can create custom concentrations and definitions inside 24 hours to meet your particular application necessities. Contact Us at info@cneverstar.com with your specifications.
Q: How do I select the right concentration for my application?
A: Choice depends on three variables: wanted pH decrease per unit weight, water affectability of your prepare, and shipping financial matters. Our specialized group can offer assistance you decide the most cost-effective review for your needs.
Q: What rising applications is the item being utilized for?
A: Past conventional employments, formic corrosive is picking up footing in coordinate formic corrosive fuel cells (DFAFC), oil and gas well incitement, biodegradable de-icing arrangements, and hydrogen capacity frameworks. These high-growth applications as of now speak to less than 10% of request but are developing 10-15% every year.
