Hallstar has published a technical paper about the function and selection of ester plasticizers, substances that are incorporated into a plastic or elastomer to increase its flexibility, workability or distensibility. Hallstar creates ester chemistry solutions for industrial polymers, as well as beauty and personal care products.
Understanding Ester Plasticizers
As Hallstar’s technical paper explains, the basic function of an ester plasticizer is to modify a polymer or resin to enhance its utility. Ester plasticizers make it possible to process elastomers easily while providing flexibility in the end-use product. They are selected based on an evaluation of cost and performance.
Plasticizer-elastomer interactions are affected by many factors, including solubility, molecular weight, and chemical structure. As this study explains, rubber compounders need to evaluate ester plasticizers based on compatibility, processability, permanence, and performance properties.
Hallstar is well known for its competency in ester chemistries and draws upon extensive market research and industry engagement. Industries served include rubber, thermoplastics, adhesives, sealants, coatings, lubricants, and agriculture.
From custom ester design to regulatory understanding, Hallstar prides itself on its extensive knowledge. The company supplies a full line of phthalate replacement plasticizers that include biodegradable USDA-certified plasticizers. Permanent plasticizers with excellent performance properties are also available.
More Technical Paper Topics
Hallstar’s technical paper begins with basics, covers functions, and presents physical properties. It also includes a discussion of four theories that describe the effects of plasticizers: lubricity, gel, free volume, and mechanistic. There’s a comparison table for polymeric plasticizers and complete list of references, too.
This downloadable resource examines plasticizer-polymer compatibility, polarity, how to select an ester plasticizer, and the effects of polymer crystallinity. It also covers phthalates, high-temperature esters, polymeric polyesters, flame retardant plasticizers, and polymeric esters for high-performance.
