Hallstar Assists DuPont with VMX Elastomers for High Temperature Resistance

Hallstar Assists DuPont with VMX Elastomers Series
Hallstar, the Chicago-based specialty chemicals company, is helping DuPont achieve new levels of high temperature resistance in its VMX series of ethylene acrylic elastomers through newly developed high-performance ester增塑剂, according to Hallstar executives.

Performing in Extreme Temperatures


Erica Anderson, senior chemist for industrial polymers at Hallstar, presented a paper on these developments at the International Elastomer Conference in Cleveland Oct. 9-12.

Anderson said at the IEC, said:

We performed this work in conjunction with DuPont for VMX. These elastomers go to even higher temperatures than before.”

According to the abstract of Anderson’s paper, ethylene acrylic elastomers are traditionally used in applications requiring performance both in extreme temperatures and when exposed to a variety of fluids.

However, the need for performance at ever higher temperatures necessitates the development of new materials to improve on permanence and volatility, it said.

This paper provides information on newly developed 增塑剂 intended to improve high temperature performance without sacrificing low temperature performance,” it said.

Better Performance in Auto Applications


According to Anderson, the new增塑剂allow DuPont VMX polymers to perform at temperatures up to 200°C. “This allows for better performance in auto applications that require high heat,” she said.

Under-the-hood applications, such as seals, hoses and other parts close to the engine, are the ones for which VMX polymers manufactured with the new Hallstar plasticizers are intended, according to Dejan (Dan) Andjekovic, Hallstar technical director for industrial polymers.

Andjekovic said:

Think of a car in Minnesota. In winter, the temperature under the hood can go down to -30°C, and the polymers cannot become brittle. But in summer the temperature can go up to 180°C in operation, so performance at both extremes is crucial.

Development of the new 增塑剂was a joint project with DuPont, according to Anderson. She said:

They provided us with materials and helped us put together an experimental plan.”

The work Anderson presented in her paper is just the first part of an ongoing project, according to Andjekovic. He said:

We hope to reveal the results of the second round of testing next year.”

Hallstar works directly with its customers to identify their problems and provide solutions, Andjekovic said:

These are proprietary platform projects for long-term market growth.

这个不错。
我们的TPE种类和加工油都及其有限。
好像只有南京一家公司在生产这种丙烯酸酯弹性体,叫金陵奥普特
