To meet the automotive and high-end rubber and plastics industries' demand for "low-temperature flexibility, heat aging resistance, and low volatility," Heritage has developed its own high- and low-temperature resistant plasticizers for synthetic rubbers such as AEM/ACM, ECO, HNBR, and NBR, positioning them as high-quality alternatives to overseas brands. 759 is renowned for its "mixed ether-ester" structure, low volatility, and ability to maintain low-temperature flexibility even in high-temperature and hydrocarbon media." Typical applications include fuel/oil contact hoses, automotive seals and gaskets, cable sheathing, and various molded and extruded products—all key application areas for Heritage's new products.

In terms of formulation, our product utilizes the same ether-ester structure as 759, balancing high polarity with high molecular weight to reduce volatility, improve heat resistance, and help the rubber retain its original mechanical and flexibility properties after heating. See the following case study for reference.

The piston dust cover in rail transit brake systems is a critical rubber component of hydraulic brake calipers, fulfilling important dust protection and sealing functions. Currently, most materials used in the industry have limitations. To address this issue, a sealing company has developed a new rubber material specifically for piston dust covers in rail transit brake systems. The plasticizer 759 used in this rubber formula provides excellent oil resistance, high and low temperature resistance, tear resistance, and flexibility. It also exhibits good processability, dispersibility, and mold release properties, making it suitable for demanding braking conditions.

Ethylene acrylate rubber (AEM) is a key material in automotive sealing systems, widely used in components such as transmission seals, cover oil pan gaskets, and filters. Its typical operating environment includes media such as engine oil and transmission fluid, and temperatures typically range from -40°C to 150°C. However, existing AEM products can experience seal failure, oil leakage, or even breakage in extremely cold environments due to insufficient low-temperature performance, posing challenges to equipment reliability. A renowned domestic automotive parts company has developed a low-temperature, low-swelling ethylene acrylate rubber material with excellent strength, swelling resistance, and low-temperature resistance (TR10 is -45°C). The plasticizer 759 used in this formula ensures that the compound retains good low-temperature flexibility even after high-temperature aging.

Heritage's Aetherium 759 plasticizer offers the following advantages:
Performance benchmark: Excellent low-temperature flexibility, heat aging resistance, and low volatility.
Supply and Service: Localized supply and technical support shorten procurement cycles.
Cost Controllable: Reduce costs and increase efficiency while meeting critical performance requirements.

Heritage continues to focus on "plasticizing solutions for extreme working conditions" from a materials engineering perspective. If you are currently using or evaluating 759, our high- and low-temperature resistant plasticizer 759 can help you validate it in automotive, cable, and rubber products.
