Our Expertise for Your Home

Large quantities, fully automated production processes, ultrafast cycle times, low costs, and top quality make the household appliances industry a fiercely competitive global business. Find out how sealing systems from RAMPF Polymer Solutions provide your products with a vital advantage!

Washing machines live longer with Calgon.

It’s a safe bet everyone will have heard this jingle at some point. However, did you know that the primary factor in prolonging the service life of washing machines is high-performance sealing systems? 

There are many places where foam gaskets are used in washing machines. While an average machine has a service life of five to ten years, higher-quality products can easily keep operating for up to 20 years. This is also possible thanks to the use of high-performance foam gaskets from RAMPF Polymer Solutions, as these contribute to both the durability and the reliability of the machine. 

Diverse industry – diverse applications

In addition to the field of washing & drying, the household appliances industry also requires foam gaskets for use in refrigerators, cooktops, and vacuum cleaners. Frequently, these use adhesive sealing solutions that combine the properties characteristic of foam gaskets with those of adhesives.

Thanks to its large adhesives portfolio, RAMPF Polymer Solutions offers a range of solutions for this, too.

However, specially formulated foam gasket solutions are required in this huge range of different applications. While the foam in refrigerators and freezers has to be particularly resistant to cold temperatures, cooktops pose particular challenges to the foam gasket in terms of mechanical strength and resistance to high temperatures. 

An overview of the requirements for the individual areas of application:

Refrigeration & freezing

  • Resistance to low temperatures
  • Universal adhesive spectrum
  • Automation enabled
  • Rapid process times

Washing & drying

  •  Resistance to moisture and chemicals
  • Universal adhesive spectrum
  • High mechanical strength
  • Automation enabled
  • Rapid process times

Cooking & baking

  • Resistance to high temperatures
  • Hydrolytic resistance
  • Universal adhesive spectrum
  • Automation enabled
  • EU 10/2010 & FDA for internal use

 Rinsing & cleaning

  • High chemical resistance
  • Hydrolytic resistance
  • Easy cleaning of components
  • Automation enabled
  • High mechanical strength

RAMPF foam gaskets and their applications

For the household appliances industry, RAMPF Polymer Solutions formulates sealing systems based on two-component polyurethane or silicone under the brands RAKU® PUR and RAKU® SIL depending on the requirements. The foam gaskets meet the highest requirements, while reliably and efficiently protecting household appliances from moisture, chemicals, and various environmental influences. 

The foam gaskets are applied using FIPFG technology (Formed in Place Foam Gaskets), a low-pressure foaming process for applying sealing systems. This type of application runs automatically, meaning large quantities with different shapes can be sealed cost-effectively and at consistently high quality. Besides the household appliances industry, FIPFG is used in many other sectors.
