NMP vs DMF, DMAc and DMSO: Choosing a Polar Aprotic Solvent NMP is the most widely used polar aprotic solvent in high-performance applications, but it is not the only one. DMF, DMAc and DMSO are used alongside it – each with a different balance of solvency, boiling point, toxicity and cost. This article compares the

NMP in Lithium-Ion Battery Manufacturing: The PVDF Cathode Slurry Solvent N-methyl-2-pyrrolidone (NMP, CAS 872-50-4) is the solvent at the heart of lithium-ion cathode production: it dissolves the PVDF binder and carries the active material into a coatable slurry. This article explains why NMP is used, how it fits into the electrode line, why the battery

Flocculant Selection Chart: PAM vs PolyDADMAC vs Polyamine by Charge and Application Organic flocculants build coagulated particles into flocs that settle, float or dewater. Choosing the right one is mostly about charge and molecular weight – after coagulation has done its job. This page pulls the three main organic flocculants (polyacrylamide, PolyDADMAC and polyamine) into

Coagulant Selection Chart: PAC vs Aluminium Sulfate vs Ferric Sulphate vs Ferrous Sulphate Coagulant choice sets the dose, the pH correction, the sludge volume and the clarity you can achieve. This page pulls the four common water-treatment coagulants into one selection chart so you can shortlist before you jar-test. The four are polyaluminium chloride (PAC),
Xanthate Collector Selection Chart: SEX vs SIPX vs SIBX vs PAX Choosing a xanthate collector comes down to two variables: the chain length (which sets the balance between collecting power and selectivity) and the ore and target mineral. This page pulls that into one selection chart you can use to shortlist a collector before lab

Sodium Ethyl Xanthate (SEX, CAS 140-90-9): Properties, Uses and Selection Sodium ethyl xanthate (SEX) is the shortest-chain of the common xanthate collectors – the most selective, and the weakest. It is used where a clean, well-differentiated concentrate matters more than raw recovery, and where the ore’s sulphides float easily. This article covers what SEX is,

Potassium Amyl Xanthate (PAX, CAS 2720-73-2): Properties, Uses and Selection Potassium amyl xanthate (PAX) is the longest-chain of the common xanthate collectors, and the strongest. Where recovery matters more than selectivity, PAX is often the collector of choice for sulphide ores. This article covers what PAX is, how it compares with SIBX and SIPX, when

Sulfamic Acid for Chloride-Free Pickling vs Hydrochloric Acid Pickling and descaling remove oxide, rust and scale from steel and equipment – and the traditional acid for the job is hydrochloric acid. But hydrochloric acid brings chlorides, fuming, and a real risk of pitting and stress-corrosion cracking on stainless steel. Sulfamic acid (CAS 5329-14-6) offers a
