Itaconic Acid Uses: Polymers, Resins and Applications Itaconic acid (CAS 97-65-4) is valuable not as a standalone product but as a versatile building block. Its two carboxylic acid groups and its unsaturated double bond let it polymerise, esterify and react in ways that make it useful across coatings, adhesives, absorbents, water treatment and specialty resins.

How Itaconic Acid Is Produced Itaconic acid (CAS 97-65-4) is one of the most successful bio-based platform chemicals, and the reason is its production route: it is made by fermentation of sugars, not from petroleum. Understanding how the fermentation works — the organism, the feedstock, the recovery — explains both its sustainability credentials and its

Magnesium Taurate vs Other Magnesium Forms Magnesium supplements can be built on many different magnesium sources, and the choice strongly affects the magnesium content, the solubility, the tablet or capsule size, and the way the product can be positioned. Magnesium taurate is one option among several chelated and inorganic forms. This guide compares them so

Magnesium Taurate: Properties, Solubility and Specifications Magnesium taurate (CAS 334824-43-0) is the magnesium salt of taurine, supplied as a white, water-soluble powder for supplement and functional-food applications. Because it is defined by a specification rather than a pharmacopoeial monograph, buyers who understand its properties — and especially its solubility and magnesium content — can specify

Buying Melatonin: What Matters Melatonin (CAS 73-31-4) is a widely traded bulk raw material, but it is not a simple commodity. The same molecular formula can be supplied as supplement grade, pharmacopoeial grade, cosmetic grade or reference standard, each with different specifications, documentation and regulatory implications. Buying well means matching the grade to your finished

How Melatonin Is Manufactured Melatonin (CAS 73-31-4) is a small indole molecule, and although it occurs naturally in plants, animals and micro-organisms, virtually all commercial melatonin is made by chemical synthesis. The manufacturing process is a good illustration of how a straightforward reaction sequence can still demand careful control to deliver the purity and colour

Buying SIS Block Copolymer: What Matters SIS block copolymer (CAS 25038-32-8) is sold against a technical specification, and two grades with the same trade name can behave very differently in the same adhesive or compound. Buying well means matching the grade to the application and confirming the numbers that govern tack, cohesion, melt viscosity and

SIS in Hot-Melt Adhesives and Sealants Styrene-isoprene-styrene (SIS) block copolymer is the base elastomer behind a large share of the world’s hot-melt and pressure-sensitive adhesives. Its combination of high tack, good adhesion, elastic recovery and easy melt processing is hard to match, and it has made SIS the reference polymer for labels, tapes, disposable hygiene

SIS vs SBS: An Overview SIS (styrene-isoprene-styrene) and SBS (styrene-butadiene-styrene) are two of the most widely used styrenic block copolymers. Both are thermoplastic elastomers with the same A–B–A architecture — two hard polystyrene end blocks flanking a soft rubber mid-block — but they differ in that mid-block: SIS uses polyisoprene, SBS uses polybutadiene. That single

Introduction to SIS Block Copolymers SIS (styrene-isoprene-styrene) is a thermoplastic elastomer built from three blocks: two hard polystyrene end blocks and a soft polyisoprene middle block. The material behaves like a cross-linked rubber at room temperature, yet it melts and flows when heated, so it can be processed on ordinary plastics equipment and needs no
