Alternatives for Kalrez® Materials
Kalrez® is a highly sought-after material for its many benefits and applications. As such, long lead times and increased costs are expected. However, there are several reliable alternatives to rival Kalrez® in functionality and results, with reduced lead times and cost-effective solutions.
Tecnoflon® is a suitable substitution for Kalrez® materials. It offers the highest performance levels among all FFKM elastomers and features extreme chemical resistance, allowing use across virtually all industries and applications. Specialty grades of Tecnoflon® can be applied to unique and demanding projects, making Tecnoflon® an underrated yet remarkable alternative to Kalrez®.
AFLAS® Premium PM-3000 and evolast® are additional FFKM elastomers that can be used in place of the highly demanded Kalrez® material. Ace Seal supplies a wide variety of FFKM products for superior performance in all sealing applications.
