Freudenberg Performance Materials has recently supervised comparative scratching tests involving its latest variant of microfilament textiles and several competitive products. Only the Freudenberg solution created no damage to painted metallic parts during this intensive lab test.
High-performance protection provided by Freudenberg’s microfilament textiles results from its unique, worldwide patented Evolon technology. Bicomponent filaments are spun, then hydro-entangled thanks to high-pressure water jets, and split to generate microfilaments that are 100 times thinner than a human hair. Unlike staple fibers, filaments cannot release fibers or lints because they are virtually endless. At the same time, extremely fine microfilaments avoid micro-scratches on sensitive parts.
Thanks to their unique construction, Freudenberg’s microfilament textiles are successfully being used by the automotive suppliers for packaging their sensitive parts during the storage and transportation process. Moreover, numerous converting possibilities of the fabric allow flexible integrating into various container systems.
In addition to automotive applications, Freudenberg’s microfilament textiles offer a high-performance solution for many other packaging applications such as consumer electronics, consumer appliances, custom countertops, aerospace products, lighting systems, and more.
The heavier grey variants of Freudenberg’s microfilament textiles for packaging, ranging from 100gsm to 240gsm, are designed for the transportation of heavy parts. EVO 200 SG SP and EVO 240 SG SP provide high mechanical strength, which make them the ideal eco-friendly substitute to conventional PVC compositions. Their good tensile strength properties remain in the range of acceptable variation ratios when exposed to outdoor conditions. Recently, some of those packaging materials have been also granted an Ultraviolet Protection Factor of 80, the highest value of the demanding “UV Standard 801.” UV Standard 801 is the only standard to verify to durability of UV protection in “real-life” heavy use conditions. Other features developed include anti-static and water-repellent treatments.
A grey 80gsm version of Freudenberg’s microfilament textiles for packaging has been recently introduced to provide an economical alternative for medium-sized parts. It is 20% lighter and offers the same anti-scratch lint-free protection and color fastness as the rest of the range. It is especially suitable for light electronic components.
Lastly, with its lighter 40gsm version, Freudenberg’s microfilament textiles for packaging material can be used for small luxurious parts. The fabric supplants PE sheets, foams and paper layers to protect small precious items such as deluxe cosmetic and perfume packaging components. The smooth soft microfilament textiles made using Evolon technology ensure no scratch or transfer of texture on the protected part. As there is no binder in the fabric, no greasy substance can release on the parts either.
