FERMAPOR CC system

Tailor-made chemistry for growing requirements.

FERMAPOR CC material systems are addition cross-linking 2-component systems for the manufacture of soft polyurethane foams. The main elements of the A component are polyfunctional alcohols, the polyols. The B component consists of the aromatic MDI isocyanate and its derivatives.

 

When component A is mixed with component B, a chemical reaction starts that, together with Sonderhoff Engineering’s newly developed FIP-CC process, leads to the formation of a strongly closed-cell polyurethane soft foam.

Low water absorption even for damaged surfaces

 

FERMAPOR CC with its smooth, slightly shiny surface gives an optically high-quality appearance. Its foam structure has very fine cells, is impermeable and extremely uniform.

Even if the surface should become damaged during application, practical trials and laboratory tests have shown that there is only a marginal change in water absorption.

Usual processing conditions - typical polyurethane

As soon as the foam has completely hardened, it can be used for applications with high sealing and quality requirements. The operating temperature range lies between -40° to +80°C, and in the short term even up to +160°C dependent on the test conditions, and is tested under real conditions appropriate to the application.

The exact hardening time is dependent on external factors such as temperature, humidity, and sealing dimension and it is also evaluated specifically for the sealed part.

Proven and new benefits - typical polyurethane

  • Predominantly closed-cell, therefore very low water absorption
  • Ice water resistant at water temperatures up to 1°C
  • No oven or humidity necessary for curing
  • Very robust, mounting-proof sealing surface
  • Low water absorption even after damage to the sealing surface (e.g. cracks)
  • Cost effective polyurethane alternative to 1-component and silicone applications
  • Formulation can be customized like mixed-cell 2-component PU
  • Thixotropic and half-thixotropic formulations available
  • Shrinking is no more possible
  • Meets the standards REACH, EC Regulation 1907/2006, RoHS

Diversity of formulations - typical polyurethane

Because FERMAPOR CC is formulated on a polyurethane basis, the know-how based on over 1,000 Sonderhoff polyurethane formulations is available for the variations of FERMAPOR CC.

Sonderhoff Chemicals’ extensive experience in developing customer-specific material systems is also completely used for this new material system. Feel free to contact us; we will be pleased to develop the suitable material solution for your requirement.
 


Das genaue Zusammenspiel unterschiedlicher Einstellungsparameter und Zusatzfunktionen der Misch- und Dosiermaschinen, die exakte Abstimmung von Bauteil und FERMAPOR K31 Schaumdichtung in der Gesamtkonstruktion sowie die richtige Materialauswahl ermöglichen erst eine wirklich sichere Abdichtung industrieller Bauteile für unterschiedlichste Anwendungen gegen Feuchtigkeit, Staub und andere Umgebungseinflüsse.

FERMAPOR CC - Processing Information

FERMAPOR CC systems are processed with 2-component medium-pressure mixing and dosing machines. The recommended processing temperature is +23° +/- 5°C. Generally, FERMAPOR CC components have a shelf-life for at least 6 months at storage temperatures from +10°up to +40°C.
