Polymer Material Systems 1001 Recipes

For Every Task the Individual Solution from Polyurethane, Silicone, and Pvc – Here, Chemistry’s in Charge

Our own research and development departments work daily to discover new and compositionally improved material systems. The choice of raw materials is an important factor here. We are researching new foam gasketing material systems for the applications of the future.

Where necessary and possible we replace existing raw materials with sustainable and environmentally friendly ones.

Individual customer specifications are converted into tailor-made products. Clients can choose the best solution from more than 1000 recipes for sealing, bonding, and potting their parts. If the customer desires, we can also create special formulas.

We create 2-component foam gasketing material systems of polyurethane and silicone for soft foam seals and 1-component PVC plastisols for the production of flexible, closed-cell foam seals. We are also producers of polyurethane and silicone potting systems for various applications. With our foam sealing, bonding and potting products, your parts get the best possible protection from damp, dust, temperature, chemicals, oils, fats, or other media. At the same time, they help to dampen sound and vibrations.

The foam gasketing materials are applied directly onto injection-molded or metal parts by Formed-in-place-Foam-Gasket (FIPFG) technology using Sonderhoff mixing and dosing systems, and cure there at room temperature.

The Six Basic Types of Material

FERMAPOR K31
Parts from numerous different fields are very often sealed using the flexible polyurethane foam gasket FERMAPOR K31.

FERMADUR
is the brand name for our polyurethane-based 2-component cast resin systems for the production of hard to gel-like potting products.

FERMASIL
is our brand name for 2-component silicone systems for the production of closed-cell silicone foam seals and of flexible silicone elastomers.

FERMAPOR CC
is the world first closed-cell foam gasket which seals the parts perfectly against water.

Individual Customization of Characteristics 

Individual customer specifications are converted into tailor-made products. In a foam seal, adjustable parameters modulate physical and chemical characteristics such as: viscosity, hardness, density, tensile strength, elongation at break, recovery capacity, water absorption, temperature resistance and width/height ratio of the foam.

With more than 1000 recipes to choose from, clients can find the best solution for sealing, bonding, and potting their parts. It is also possible to create a special formula to meet our customers specific needs. Our application technologists with the specialist knowledge and many years of experience, provide expert answers to your queries regarding the right material system so you can find the perfect sealing solution for your components.

Special Properties for Special Requirements

We offer you a wide spectrum of product properties suited to the varying usage conditions and quality requirements of your components. The FERMAPOR K31 foam gasket systems are characterized by a very broad profile of properties for the most varied part applications.

FERMAPOR K31 Fast-cure

The very rapidly reacting polyurethane-based foam seals FERMAPOR K 31 FAST-CURE allow an early start to further processing and final assembly thanks to their very low tack-free times of 2-3 minutes and are especially useful for rapid cycle times.

Our special fast-cure foam seals meet the house technical requirements of manufacturers within the automotive industry.

FERMAPOR K31 Low-emission 

FERMAPOR K31 LOW-EMISSION foam seals achieve the target values for VOC emissions of 100 µg and for fogging behavior of 250 µg per gram of polyurethane in accordance with DBL 5452-13 (Daimler).

Other automotive manufacturers have similar target values for fogging behavior, thermal desorption (VOC) and formaldehyde emission, which are also reached by FERMAPOR K31 LOW-EMISSION.

FERMAPOR K31 Antimicrobial 

The polyurethane-based foam seals FERMAPOR K31 with antimicrobial protection fulfil the hygiene demands for air-conditioning systems and devices in accordance with VDI 6022 (testing for microbial metabolization ability, sheet 1 (04/2006)).

They possess high resistance to fungi and bacteria in accordance with DIN EN ISO 846 (determining the effect of micro-organisms on plastics)

FERMAPOR K31 Flame Protection

The FERMOPOR K31 foam gaskets with flame protection fulfil the highest US fire safety prescriptions according to UL 94 V-2 by independent organization Underwriter Laboratories. This means that foam gaskets with flame protection are self-extinguishing when exposed to flame. Burning sealing material, which could still cause a fire, does not drip off; the fire goes out.

FERMAPOR K31 FDA

The polyurethane foam gasket FERMAPOR K31 FDA conforms to the standards of the US Food and Drug Administration (FDA). They are considered the recognized standards for food packaging worldwide.

FDA-approved polyurethane foam is suitable as a lid seal for direct contact with aqueous, acidic, alcoholic, fat-containing and dry foodstuffs in plastic packaging. At the same time, FERMAPOR K31-A-6505-1-N-FD polyurethane foam gasket is approved according to EU regulation No. 10/2011. And thus fulfils the requirements under §§30 and 31 of section 1 of the German food and fodder laws (LFGB), as determined by the guidelines laid down by the European Food Safety Authority (EFSA).
