ZetexPlus® Fibre
Final Advanced Materials offers a complete range of Zetexplus® products: tapes and fabrics.
What are ZetexPlus® Fibres?
Our partner Newtex offers a wide range of fire resistant and temperature resistant products since 1978. The Zetex® and ZetexPlus® ranges present a great variety of heat resistant textiles which can withstand temperatures up to 1,095 °C. Due to their characteristics and performances, these products are ideal for fire protection.
ZetexPlus® products are insulation and protection textiles against high temperatures. They can be used as gaskets, welding blankets and equipment protection, lagging, welding stress relief, removable insulation pads… ZetexPlus® fabrics are woven from continuous filament fiberglass yarns that have been treated by Newtex's proprietary texturization process. Their thermal conductivity is 0.05 W.m-1.K-1: they withstand heat but also cold, down to – 73 °C. ZetexPlus® products have a good dielectric resistance and interesting mechanical properties which can be improved with specific coatings. The fibre is chemically inert and resists well to chemicals and abrasion.
Manufacturing of ZetexPlus® Fibres?
The first steps of the manufacture of ZetexPlus® fibre are similar to the one of standard E-glass fibres. Once a thread is produced, it is cut open by a compressed air nozzle to amplify its volume. The texturization process is key because it gives the high temperature fabrics superior insulation capabilities. While the process stops here for Zetex® fibres, ZetexPlus® fibres undergo an additional treatment with vermiculite coating to enhance their resistance to high temperature. The texturized thread can then be woven, braided or twisted to produce fabrics, tapes and ropes.
General Characteristics of ZetexPlus® Fibres
Mechanical Properties
For an equal diameter, Zetex® fibre is twice as strong as a steel wire. The mechanical quality of the Zetex® fabric offers all kinds of thermal protection. ZetexPlus® outdoes Zetex® by 40 %.
