Foaming agents, also known as chemical blowing agents or (CBA), can be used in all conventional plastics processes including extrusion, calendering , injection molding, coatings, rotational and slush molding and many others. One of the advantages of foamed plastics are the reduction in density, savings in material costs, improved thermal and electrical isulative properties, increased... Read more »
Mainly used as a nontoxic plasticizer in PVC, cellulose resin and synthetic rubber, Acetyl Tributyl Citrate (ATBC) is also valued for its biodegradability in nail polishes and other cosmetics. ATBC provides many improvements over di-butyl phthalate in cellulose nitrate films due to its lower volatility, better resistance to yellowing and better adhesion to metals. It... Read more »
Epoxidized soybean Oil (ESO) is an additive to flexible Polyvinyl Chloride (PVC) that gains its name from the reaction that occurs with the unsaturated soybean oil. The epoxidation reaction takes place at a carbon to carbon double bond site. The oxygen atom (usually in the form of a peroxide or a peracid) comes in and... Read more »
In concrete, producing an effective concrete-air content is a vital aspect. Though the air reduces the strength of the concrete, the air does add compressibility to the concrete. This makes the concrete more durable through temperature changes allowing the concrete bend and flex in very high or very low temperature conditions. There are situations when... Read more »
Sebacic Acid is a castor-derived fatty acid and a precursor to various esters such as dioctyl sebacate, dibutyl sebacate, and dimethyl sebcate. While the price is often tied to the castor crop yield each year, many consumers of Sebacic Acid have become curious about how the chemical is produced from its castor oil feedstock. Although...

Synthetic Esters fall into API category Group V fluids. These esters are synthesized through reaction of a carboxylic acid and an alcohol, and due to the chemical variety of such building blocks there are numerous synthetic esters commercial available on the market today. Because ester chemistry is so varied and esters can be linear or... Read more »
Epoxidized Soybean Oil (ESO) is a non-toxic, non-hazardous, and naturally-based plasticizer and stabilizer for flexible PVC applications. The ESO supplied by ChemCeed is produced from locally grown Midwest U.S. soybean crops and is manufactured by North America’s leading farmer-owned cooperative, CHS. An industry leader in soy processing, CHS processes more than 120 million bushels of... Read more »
Diisononyl Phthalate (DINP) is a preferred choice PVC plasticizer for large-volume general use applications by balancing cost savings with good processablity. DINP is highly compatible and can be used with many secondary plasticizers to maximize cost effectiveness. It is often used as a substitute for Dioctyl Phthalate (DOP) and shows lower volatility than DOP. DINP... Read more »
Due to growing consumer pressure over phthalate plasticizers, many manufacturers are challenged with the problem of reformulating a phthalate-free product while maintaining the same cost and performance. Although there are now a growing number of drop-in phthalate replacement plasticizers on the market for all types of polymer applications, especially polyvinyl chloride (PVC), they often come...

DUP is a linear phthalate ester plasticizer which is produced from a mostly linear C11 alcohol. Due to its excellent high temperature properties, DUP is a good choice when high temperature stability is required. DUP boasts strong outdoor weathering capabilities and good low temperature flexibility properties, making it a prime plasticizer for long-life outdoor products... Read more »
