The all-rounders based on Polyurethane and Silicone
Sealing Systems
Reliable and efficient protection
The basic task of sealing systems is to efficiently protect components against moisture, chemicals, and various environmental influences.
RAMPF Advanced Polymers is a leading specialist in liquid to highly thixotropic two-component foam gaskets and elastomer seals based on polyurethane and silicone.
The foam gaskets are processed using FIPFG (formed in place foam gasket) or FIPG (formed in place gasket) technology.
The advantage: Unlike inserted or stuck-on seals, our sealing systems are applied directly on the component by dispensing machines. They expand in situ and bond very quickly, which reduces cycle times and also ensures more efficient processing.
Our RAKU® PUR and RAKU® SIL systems combine efficient sealing with the highest quality and exceptionally easy handling.
By developing new products and optimizing existing ones, RAMPF Advanced Polymers ensures the toughest demands in terms of seal quality, sealing geometries, and mechanical, thermal, and chemical resilience are always met.
What’s more, processing properties such as reactivity, viscosity, and color can be tailored to customer requirements.
