PTFE mesh fabric is manufactured from a PTFE coated fiberglass mesh and is commonly used in high temperature applications that require good air flow though the belt. The PTFE coating also provides excellent release properties making it popular for a wide range of product transfer and drying applications. Our Porous PTFE mesh belting can be manufactured into endless conveyor belts with sealed edges to your requirements.
* Outstanding temperature resistance (from -70ºC to +260ºC)
* Resistant to corrosive caustic cleaning agents
* Resistant to corrosive agents
* Low thermal mass
* Controlled porosity
* Superior non-stick surface, easy to clean
* High dielectric strength
* Dimensional stability
* Resistance to UV, IR and HF
* Superior tracking
PTFE mesh sheet can be used for textile drying, screen print drying, packaging machines, shrink wrap, drying lines, food transfer.
There are many variations of PTFE coated open mesh materials. There are three main common substrates used which are fiberglass, Aramid (Kevlar) and Nomex. Fiberglass is the most common with Nomex being a rare choice.
The mesh size or aperture can vary in size ranging from 1mm to 8mm square with the most common size being 4mm square. The weave style can vary too. The most common weave style tends to be tightly wound weft threads and lino weave warp threads. Some grades have two weft threads next to one another and are referred as double weft versions which can offer a higher level of dimensional stability over standard versions.
PTFE mesh fabric tends to be used to allow airflow to pass through and circulate with ease allowing effective removal of moisture to take place within a wide range of drying oven units.
PTFE coated Kevlar mesh maybe specified where high levels of moisture may be present or environments where steam is introduced directly on to the belts surface. Glass mesh in these environments would simply breakdown quickly where as Kevlar is resilient to this.
PTFE mesh belt can be coated as wide as 3250mm which is much wider than standard closed weaved PTFE fabrics. Wider materials options give oven manufacturers the flexibility to design much wider dryers providing higher throughput and production volumes for the end users.
