产品

Vamac® ethylene acrylic elastomer, introduced in 1975, has been successfully used for many years in demanding automotive applications, where excellent resistance to heat, engine and transmission fluids or Blow-By is required. our latest manufacturing technology allows production of enhanced AEM grades that have significantly improved compared to the existing standard Vamac® elastomers. These grades, designated and sold as Vamac® Ultra, provide a step-change improvement in processability, performance and customer value for targeted applications, including for peroxide cure E/MA dipolymer grade with Vamac® Ultra DX (formerly VMX2122).

Bale size is nominally: 560 x 370 x 165 mm

Major Performance Properties and Applications

Higher viscosity is the major difference between the standard AEM grades and the Vamac® Ultra family of polymers. Four Terpolymers of the Ultra grades, cured by Diamine curatives, are now commercial. Vamac® Ultra DX is a high viscosity version of Vamac® DP. It provides improved mold release, and is comparable to Vamac® Ultra Terpolymers.

Increased green strength of compounds helps to avoid collapse during extrusion processes, and may help in applying reinforcement layers without cutting the inner tube by filaments. The optimized polymer structure ensures gains in physical properties, resulting in improved performance of rubber parts such as cables, seals, gaskets or extruded hoses.

Best physical properties of Vamac® Ultra DX are obtained in rubber parts having a hardness range between 50 and 90 Shore A.

Compound and Vulcanisate Properties

Compounds of Vamac® are formulated and processed by customers to meet their own specific performance requirements. Many of the highest-performing compounds are vulcanizates of Vamac® are proprietary, and cannot be published. We have independently formulated a wide variety of Vamac® compounds for its own short- and long-term properties testing programs.

A typical compound of Vamac® Ultra DX with Carbon Black is reviewed below. Vulcanizate performance test data are given to help endusers evaluate the potential fitness of similar compounds for their own applications.
