Johns Manville’s needle mat is manufactured by bonding glass fibers via mechanical needling. Due to its voluminous product structure, JM needle mat is a great option for use as thermal insulation in canteen kitchen appliances, gas turbines and manufacturing facilities.JM European-origin, white glass fiber needle mat is available in area weights from 300 to 4,600 g/sqm and thicknesses from 4.5 to 25.0 mm.Johns Manville’s melt-blowing process creates fibrous webs directly from polymers using high-velocity air to attenuate the filaments. Due to differences in filament size, meltblown nonwoven fabrics differ in degree of softness, opacity and porosity. Johns Manville synthetic spunbond nonwovens are made by spinning continuous polyester fibers onto a moving belt. The continuous fibers come from polyester raw material that has been dried, melted and extruded into a flowing polymer melt. After the spinning process, the polyester emerges as several thin, continuous filaments. These are cooled, stretched and solidified to consistent dimensions before being laid on the belt to form a mat.Depending on customers requirements, we have the ability to vary JM bonding technologies. JM nonwovens can be bonded thermally, mechanically or chemically - each process resulting in highly differentiated characteristics.
Johns Manville fibers may be hidden from view, but their effects are plain to see. We combine JM glass fibers with plastics to mold stiffer, stronger and lighter weight products. We cover an array of markets and applications, which we detail below to help guide you in the right direction. You’ll also find detailed product information about JM fiber offerings. In addition, we can tailor JM products or solutions to satisfy the technical needs of your particular application. We will help ensure the solutions we manufacture for you are made with fibers of the highest quality. It is JM goal to give you the highest level of confidence throughout every stage of the process. Glass Nonwovens Air/Wet-Laid,Utilizing a unique and sophisticated process, JM glass microfibers are conveyed in a high-velocity air stream and formed into a nonwoven mat. The binder is spray applied and oven cured. This material can be manufactured with polyester spunbond or glass backing material. The resulting high-loft nonwoven material is mainly used in HVAC(heating,ventilation,air condition) systems as a highly effective filtration media.Johns Manville’s nonwoven glass mats are tailored to meet your needs. We start by selecting the JM fiber glass that best suits your end-use application. With JM large family of glass chemistries, we are able to blend in polymer fibers or glass microfibers when fiber glass alone does not suffice. And depending on your requirements, we have a selection of formaldehyde–free, acrylic, urea formaldehyde and other resin binders. The finished mat can then be custom slit to a width and wound to a diameter that works with your manufacturing process and/or your end product.
