FERMAPOR CC - Closed-Cell Polyurethane Foam Gaskets

Tailor-made Polyurethane Closed-Cell Foam Gasket Systems 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 the developed FIP-CC process, leads to the formation of a predominantly closed-cell polyurethane soft foam.

Overview

Low Water Absorption Even for Damaged Surfaces

FERMAPOR CC foam 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, 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
  • Curing at room temperature, 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 1K PU and 1K or 2K silicone foam gasket applications
  • Formulation can be customized
  • Thixotropic and half-thixotropic formulations available
  • Dimension stable sealant (shrinkage is not possible)
  • Meets the standards REACH, EC Regulation 1907/2006, RoHS

Technology

Diversity of Formulations - Typical Polyurethane

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

Our extensive experience in developing customer-specific material systems is also completely used for this new material system.

The exact interaction of different setting parameters and additional functions of the mixing and dosing machines, the exact matching of the component and FERMAPOR K31 foam gasket in the overall design and the correct choice of material are what makes a truly reliable seal for industrial components for the most diverse applications against moisture, dust and other environmental influences possible.

FERMAPOR CC - Processing Information

FERMAPOR CC systems are processed with 2-component medium-pressure SONDERHOFF mixing and dosing machines. The recommended processing temperature is +23° +/- 5 °C.
