| General Characteristics and Applications | LSP 90/AFF is a reticulated polyuretherane foam (Polyester based); the cellular network is entirely open and does not contain any closed cells. This is obtained by a thermal reticulation process by which all cell membranes which still remain after the foam formation are melted into the cell ribs.
Thanks to its calibrated cell size, the homogeneous cellular structure and the three-dimentional network, this foam is an ideal support for filtration and prefiltration of air in the automotive industry, air conditioning and ventilation. The calibrated cell size and openess ensure a reproducible filtration efficiency, while the three-dimensional network allows a high dust load without affecting the pressure drop significantly. Finally, the foam can be shaken, washed, rinsed…and can thus be reused many times. The volume taken by the foam ribs only represents 3% of the foam volume. It is not subject to “swelling” in the presence of water, fuel, soaps and detergents, mineral oils, greases etc. However, most of the organic solvents swell the foam, the extent of the swelling varies from one solvent to another. |

LSP 200 Specifications
| LSP 200 – A | ||
| The demand for environmentally friendly insulation material with minimum smoke and toxic emissions in the event of fire is gaining importance. LSP200A meets this demand.
The flammable nature of polymer products can be reduced with the use of specific flame proofing agents. LSP200A contains no flame proofing agents, PVC, CFC or HCFC’s. This halogen-free insulation has been specially developed to reduce smoke density to a minimum in the event of fire and to eliminate, as far as possible, any toxic contamination such as dioxins and furanes. If LSP200A is exposed to severe fire it will burn like any other organic material. However, the flammable components do not contain any corrosive or decomposing elements. LSP200A provides protection against diffusion of water vapour as closed cell material, and features all the properties which you can expect from a flexible insulation material such as low thermal conductivity; dust and fibre free. The competitive advantage of specifying LSP200A:

| LSP 200 – RA112 | ||
| RA112 is a black expanded closed cell Nitrile/PVC elastomer designed to conform to industry standard ASTM and SAE Specifications. It is specifically formulated from synthetic butadiene/acrylonitrile copolymers and engineered flame retardents, making it ideal for a variety of high performance gasketing and insulation applications. The material’s low density and medium firmness make it ideal for areas, where a tight, compressible seal is required. The product contains no CFC’s or other Ozone-Depleting Chemicals per 40CFR Part 82, and is free of heavy metal components, such as, lead, cadmium, chromium, antimony and mercury, thus facilitating eventual recyclability. RA112 is generally supplied as continuous master rolls in thicknesses ranging from 3 to 25mm, and in widths up to 1.4 metres (54 inches). Typical properties of RA112 are listed below. | ||
