Expert in high temperature insulating technical felts
Apronor >
Apronor offers high temperature insulating technical felts. The fibers used for their manufacture are chosen with care, according to their properties.
Resistant to high temperatures, these technical textiles provide excellent insulation (thermal, acoustic, etc.). Applications vary by product, as do density and thickness. But all are characterized by their heat resistance and the protection they offer. Likewise, most of our felts are available in several references. You therefore benefit from a wide range of insulating textiles.
Technical felts
Apronor technical felts (glass and silica needle felts, papers, webs and loose fibers) are very good insulators due to their specific composition. They are intended for applications in high temperature conditions.

Needle felt is a very good insulator, the thermal conductivity of which is very low. It is available in several thicknesses and densities. Due to the needling process, the mechanical strength is very good. There is no binder so very little smoke is released. Needled mats are nonwoven textiles made with textile fibers held together by their individual adhesion, which is consolidated by mechanical methods.

Bulk fibers
Made from a spun and blown technique, the bulk fiber has a fluffy, choppy and fluffy appearance. It is composed of calcium, magnesium and silicate with a low thermal conductivity which gives it very good heat resistance. Bulk fiber is a versatile material commonly used by manufacturers of insulation products and is ideally suited for conversion into vacuum cast panels, liners and form parts.
Loose fibers and biosoluble chopped fibers offer many advantages over other mineral fibers:
- Thermal and physical stability up to 1200°C
- Exceptional sound absorption properties
- Excellent wet forming characteristics
- Suitable for making textiles
- Efficient energy savings
- Base product for vacuum forming
