"Polymer Modification Roadmap for Elastomers: Plasticizers
Join us on Thursday, July 28, 2025, from 2:00 – 3:00 PM (ET) for a free webinar about Hallstar ester plasticizers and magnesium oxides. In this webinar, Hallstar experts from both its technical and commercial teams will present a deep-dive into plasticizer selection and demonstrate how their high-quality magnesium oxides make it the leading brand for critical elastomer applications.
Hallstar Evaluating Plasticizers in High Temp Applications
elastomers are too volatile, extractable or incompatible with the higher-performance elastomers. This article provides information about plasticizers that our research has shown are suitable for these high-performance acrylics and highly saturated nitriles. Plasticizers are commonly used only for their as molded low-temperature contribution.
Plasthall | Hallstar Industrial
Plasthall114 is a proprietary, aliphatic ester plasticizer used to modify high-polarity thermoplastics and elastomers. PLASTHALL 100 Plasthall 100 is the monoester isooctyl tallate. It has excellent compatiblity in polychloroprene as well as chlorosulfonated polyethylene and natural rubber.
Renewable Plasticisers | Hallstar - Hallstar Industrial
HallGreenproducts function as process aids as well as polymer and impact modifiers. They improve processing by reducing melt viscosity/temperature, and energy consumption. As polymer/impact modifiers, they reduce brittleness, improve impact resistance and improve extruder flow rates and throughputs.
Hallstar | Innovative, leading-edge, ester chemistry solutions
New Innovations New polymeric esters from Hallstar have been specifically designed to be highly compatible with low ACN (H)NBR, EPDM, TPV, TPO, PE and PP polymer compounds. The polymeric nature increases modifier permanence without sacrificing low temperature and general mechanical performance.
- What is a reactive ester plasticizer for elastomers?
- Reactive Ester Plasticizer for Elastomers Stephen O’Rourke, Technical Director, Industrial Ester plasticizers are traditionally used to provide low temperature and improved processing of elastomers. New esters have been designed recently to improve the permanence of these materials when subjected to high heat and fluid extraction.
- Are ester plasticizers good for polar elastomers?
- Ester Plasticizers for Polar Elastomers with Emphasis on Low-TemperatureEster plasticizers contribute processing advantages to rubber compounds made with polar lastomers, much the same as petroleum oils do for low polarity rubbers. By definition, a plasticizer is "a compoun
- Are plasticizers effective in reducing low-temperature elastomer test values?
- Plasticizers, when added to acrylic elastomer compounds, can reduce the low-temperature test values obtained compared to unplasticized compounds. Of the monomeric plasticizers tested, DB(3E)A and DADEG appear most effective. It should be noted these are the highest molecular weight of the monomeric esters tested.
- Are elastomers a plasticizer?
- Common esters and polymeric polyesters are both external and physical plasticizers. Physical plasticizers may have some weak attraction to the polymer, such as through hydrogen bonding or Van der Waals forces, but, as with external plasticizers, they do not chemically react with the elastomer.
- How to choose an ester plasticizer?
- The rubber compounder must evaluate ester plasticizers for compatibility, processability, permanence and performance properties. The study of these properties by the rubber compounder will help in selecting an ester plasticizer. ASTM D883, "Plastics Nomenclature," American Society for Testing and Materials, Philadelphia, PA.
- Why do we use ester plasticizers?
- Ester plasticizers make it possible to process elastomers easily while also providing flexibility in the end-use product. Plasticizer–elastomer interactions are governed by many factors, such as solubility parameter, molecular weight and chemical structure. Ester plasticizers are selected based upon a cost/performance evaluation.
