Sealing Systems

Reliable and Efficient Protection

The main task of sealing systems is to effectively protect components against moisture, chemicals and various environmental influences.

RAMPF Polymer Solutions is a leading specialist in polyurethane and silicone based, liquid and thixotropic two component cast gaskets.

Polyurethane and silicone cast gaskets are processed using FIPFG (formed in place foam gasket) or FIPG (formed in place gasket) technology.

Compared to the ready-made gasket systems that are glued by hand, cast gaskets are directly applied to the desired surfaces with dosing units or cast gasket machines, providing fast adhesion and rapid mass production, minimizing process times and producing much more efficient results.

Our RAKU ® PUR and RAKU ® SIL systems provide the highest quality and ease of use with their highly efficient sealing.

By developing new products and optimizing existing ones, Rampf always meets the toughest demands in terms of gasket quality, sealing geometry, mechanical, thermal and chemical resistance.

According to customer requests, reaction rates, viscosity and color options can be adjusted with endless formulation options.
