PET Bitumen Roofing Substrate Production with Oerlikon Neumag Spunbond Technology

One basis, many possibilities
The basis for an excellent end product is an optimum spinning result. It makes no difference whether you want to produce bitumen roofing substrates, roofing underlayments, geotextiles or other techncial nonwovens, our spinning technology is the ideal starting basis.
For optimal spinning, the polymer must be distributed in the spinning beam under very uniform conditions. With our segmented distribution system, a uniform residence time and heat transfer is achieved for the polymer across the beam and spinneret. As a result of the excellent polymer distribution, our spunbond technology achieves homogeneous web characteristics. To this end, consistent tenacity and elongation values in both cross and machine direction, are achievable. The result is Bitumen roofing substrate nonwovens from 100% PET spunbond with our technology are comparable to glass fiber reinforced products.
