The basic task of sealing systems is to efficiently protect components against moisture, chemicals, and various environmental influences.
RAMPF Group, Inc. 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 taped 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.
Formed-in-place sealing systems based on polyurethane (RAKU® PUR) and silicone (RAKU® SIL) from RAMPF Polymer Solutions provide components with reliable and efficient protection against moisture, dust, chemicals, and various environmental influences.
Unlike gaskets that are inserted or stuck on, liquid gaskets
are applied directly onto the component using a dispensing machine. The material adheres to the component very quickly and forms a secure bond.
The sealing systems adapt perfectly to the component and lie stress-free in the groove. The chemical properties are tailored to the relevant requirements.
FIPG and FIPFG sealing systems are an established standard in a number of industries, including automotive, household appliance, electronics, control cabinet ,and lighting.
Our products can easily be adapted to meet specific requirements and are constantly being developed, making them the number one choice, even when it comes to newly emerging application areas such as e-mobility.
RAMPF Polymer Solutions is your expert partner in polyurethane- and silicone-based sealing systems. Choosing the best possible sealing material depends on the requirements profile of the end properties and on the manufacturing process.

| Feature | Benefit |
|---|---|
| Automated process offer great flexibility | Thousands of programs can be used to reduce gasket warehouse space, inventory and it's cost |
| Bond quality is permanent, if desired | The FIP gaskets will remain bonded in the cold and heat, unlike PSA tapes, improving performance and quality |
| FIP gasketing creates a seamless gasket without waste | Save labor and material costs, compromised quality and performance compared to die-cut or gasket tape |
| Integral skin throughout the gasket | Provides better cut resistance and water absorption resistance for higher performance over the years |
| Automated process reduces labor | The labor reduction allows operator to be reallocated and saves money in the gasketing process |
| Material cost is typically fractions of a cent per inch | Low material costs saves significant money versus strip or die-cut gaskets |
| Application speeds up to 16" per second | High-speed application increases productivity and reduces labor resulting in greatly reduced costs |
| Accurate placement of the gasket every time | Improves quality, performance, customer satisfaction and reduces scrap as well as rework saving cost |
