RAMPF Giessharze develops foam gaskets capable of high pressure processing

RAMPF Giessharze is extending its product portfolio. For the very first time, the reaction resin specialist is offering a foam gasket system with high-pressure processing capability which will go by the name of RAKU-PUR® 35-3500 HD. The new polyurethane system, which is characterized by extremely minimal water absorption, is capable of being processed using reactive high-pressure systems.

Door module sealed with hig-pressure foam gasket

RAKU-PUR® 35-3500 HD is perfectly formulated for high-pressure processing. Its excellent mechanical strength makes this foam ideal for sealing door modules.

The new foam gasket generation from RAMPF Giessharze is ideally formulated for high-pressure processing, whether two or three-dimensional. The delayed reaction of the foam sealant ensures optimum mixing in the mixing head. The fast curing properties of the material without the need for a curing oven following direct application onto the component allow fast further processing. The product characteristics of the gasket speak for themselves: RAKU-PUR® 35-3500 HD offers an impressive specific gravity of 260 g/l, extremely low water absorption, a good appearance and minimal density. The foam also forms a clearly defined skin and offers excellent mechanical strength. The latter is a requirement frequently imposed by today’s automotive industry, and is of particular importance where shearing forces occur during the assembly of functional components.

When applying using the high-pressure method, small dispensing rates of 3 to 5 g/s are possible. The experts at RAMPF Giessharze tailor the new polyurethane system precisely to individual customer needs. RAKU-PUR® 35-3500 HD is available with a range of different properties – from liquid to highly thixotropic. It adheres successfully to different surfaces. When working with some plastics, adhesion can be achieved by pre-treatment with primers or Plasma Treat.
