Aircraft Engine Inlet covers

Problem: a customer working for Airbus required a cover that resisted all types of weather, was flame retardant to FAR 25 and was not affected by hydraulic oil (Skydrol). A synthetic rubber (chlorosulfonated polyethylene) was previously used for this application but that was becoming increasingly difficult to source and was environmentally challenging to apply. It also had to be printable.

Solution : A specially developed Polyurethane coating is applied to a HT Polyester basecloth and then laminated to a meta-aramid knitted fabric. This gives flame retardancy to FAR 25. The cold flexion is tested to
-55°C (-67°F) and the contact and convective heat resistance up to +180°C (+356°F).
It is compatible with Skydrol hydraulic oils. Ice does not stick to the fabric and the UV resistance is excellent. It is also screen-printable.

Meltex seaming tapes

Problem: stopping rain from penetrating convertible car soft tops is a technical challenge. The tape has to stick to the interior fabric, withstanding regular folding and unfolding. The tape has to be extensible to avoid puckering. It also has to hide the seam and look neat.

Solution: by taking a Polyamide basecloth and coating it with our Meltex hotmelt, we ensure perfect water tightness. A biased cut gives stretch to enable the tape to follow curves without puckering. This fabric will adhere to dry fabrics such as polyester, polyamide, cotton….and also coated fabrics (PVC, compact and microporous PU, neoprene, leather….). Can be slit to order. Welding with seam tape welding machines.

Automobile exhaust gas ducting

Problem: the ducting leading from the exhaust pipe to the pollution testing machine has to withstand high temperatures. It also has to be flame retardant and weldable.

Solution: a HT Polyester basecloth gives good mechanical strength. A specially formulated Polyurethane coating gives high temperature resistance up to +180°C (+356°F). The flame retardency is M1: it is weldable by hot air and high frequency. The fabric is supple even at very high temperatures with good resistance to hydrolysis, ammonia, diesel and ASTM oil.


Problem: asphalt transport companies were looking for a solution to keep the asphalt warm between loading and arrival at the road works site. If the temperature drops below 125°C, the asphalt is unusable. The dump truck covers are traditionally made from PVC coated fabrics but the asphalt sticks to them and makes covering and uncovering difficult, if not dangerous for the drivers.

Solution: choosing a HT Polyester basecloth in 1100 dtex gives very good mechanical strength. A specially designed silicone coating on both sides ensures temperature resistance up to +200°C permanently (no degradation in tear strength after 1 hour at 200°C: NF EN 12280). The fabric is easy to clean and asphalt will not stick to it. The silicone reflects heat from the asphalt downwards, keeping the heat in and preventing condensation. Being lightweight (370 g/m²), the fabric is easy to handle.
