Sliding agents for window rubber seals

GETREN® P SERIES


Whenever different surfaces come into contact, friction occurs. The assembly of rubber profiles into flat paneled window frames clearly shows this effect: The rubber and the frame rub against one another and it requires a lot of power to assure precise positioning of the window components. Using a sliding agent that forms a lubricating film on the profile considerably facilitates this process, as friction is being reduced.


Sliding agents made by Evonik, the  GETREN® P series, are based on silicone oil emulsions or organo modified siloxanes (= OMS). They can be applied by either dipping or spraying after vulcanization, offer excellent 
sliding properties  and are suitable for the use on Plexiglas® or polycarbonate plates without causing stress cracks. 

While silicone oil emulsions are the traditional  solution, sliding polymers based on OMS are a more advanced generation of sliding agents offering a significant benefit: Converse to silicone oils that never dry out completely, OMS based products form a dry film on the profiles. OMS must not be mistaken with silicone oils which 
are polydimethylsiloxanes  (PDMS). 

Evonik works also closely with externaland renowned third party institutes forfield testing and further product developments.
