This form of closed cell foam is cross-linked using a physical method rather than chemicals. The benefit of this irradiation process is that after the foam cells have been interwoven there is no debris of any kind left behind. You can differentiate this foam by the shinier and flatter cell surface and by the smaller, rounder cells with their finer cell walls. These foam types feel softer to the touch.
These safe, durable and lightweight foams have regular or fine closed cell structures that ensure low water absorption values and very low water vapour permeability. These qualities make them good weather resistors when combined with their wide working temperature ranges. Their excellent thermal stability means that they have low shrinkage values even at elevated temperatures.
Depending on the grade chosen we can supply rolls that range from 50 to 200m in length, 1 to 1.5m in height, 2 to 10mm in thickness and with densities ranging between 28 to 57kg/m3.
The very good impact sound insulation properties of these types of foams at low thicknesses, coupled with their excellent thermal insulation characteristics make them popular in the automotive industry for use as sealing gaskets against air, moisture and dust and as protection against noise and temperature. Also as they are highly elastic they also allow the mounting of parts against uneven surfaces.
Other applications, such as fillers in roofing or cladding for construction, are assisted by the benefits of their dimensional stability and resistance UV and rotting.
The physically cross-linking method of production means they are inert to a wide range of chemicals, have no odour and because they are ecologically and chemically inert their disposal, if necessary, can be facilitated by recycling, landfill or incineration. CFCs, plasticizers or toxic heavy metal based substances are not used in the manufacture of these foams making them environmentally and biologically friendly.
These roll foams are suitable for die cutting, embossing, bonding, heat welding, lamination and press forming.
Common uses: Footwear, underlay, gaskets, leisure mats, swimming pool liners or covers. Used for high-end packaging due to its superior presentation appearance and improved performance. Tape manufacturers also make this their foam of choice because of its improved flat surface and low extrusion thicknesses.
