High-performance elastomers – individual and market-driven

High-performance elastomers from KACO

KACO develops high-performance elastomers to customer specifications and according to the needs of the market. We develop materials for our own use and for other companies that work with elastomers. All the high-performance elastomers are produced in a dedicated mixing plant according to very strict quality requirements. This is what forms the high reliability that distinguishes KACO products and is demanded by our customers.

FPM: the first choice for shaft seals rings

KACO's range of FPM materials includes bisphenol and peroxide-cured types with glass transition temperatures from -4 °C to -40 °C for static and dynamic applications in the hardness range of 50 to 90 Shore A. The upper temperature limit is over +200 °C. The materials can be worked in the CM, TM and IM processes, as well as in cold runner and valve gate systems. They are primarily used for shaft seals rings in the area of engines, fuel pumps and transmission.

ACM: tried and tested in static and dynamic sealing systems

KACO offers various ACM compounds in a hardness range of 65 to 80 Shore A and a thermal application range of -30 °C to +150 °C. Three new HT-ACM compounds expand the application range to -35 °C to +170 °C. Of course, these materials can also be worked using all known production methods, including cold runner and valve gate systems. These high-performance elastomers are used in static and dynamic sealing systems.

AEM (VAMAC): easy to work

AEM materials are available from KACO in the hardness range of 60 to 90 Shore A. Their oil resistance and glass transition temperatures vary according to requirements. They can be processed very effectively in modern manufacturing procedures. All AEM materials from KACO are DOTG-free. They are primarily used in so-called "gearbox pistons" and in static sealing systems.

HNBR: perfect for strict temperature requirements

Due to the strict temperature requirements for our products, HNBR materials from KACO are fully hydrogenated and peroxide-cured. The materials are available in the operating temperature range of -40 °C to +135 °C and in hardness ranges from 50 to 90 Shore A. The HNBR materials are used in sealing systems for the vehicle coolant system, in power steering systems and in air intake and outlet management for engines.

PTFE compounds: special developments

For years, radial shaft seals rings (RSSR) with a PTFE lip have replaced classic FPM RSSR in crankshafts and camshafts. Together with a leading PTFE compounder, KACO has developed multiple PTFE materials for this use. In addition, there is a PTFE compound for sealing systems in fuel pumps.
