The continuous cooperation with worldwide research institutes and universities enables us to meet customer-specific requirements and develop customized products. Feel free to contact us! We are eager to find intelligent, efficient, and future-oriented solutions with you and for your applications.
Our unique process ensures success
A perfect pair: silver and polyamide! The polyamide gives the yarn strength and elasticity, while silver is:
- shielding against electromagnetic waves
- electrically conductive (ideal for Smart Textiles and Smart Wearables)
- thermally conductive
- anti-static
Due to its various properties, a wide range of applications for our products has opened up. We are involved in various projects of sensors technology, actuator technology, smart textiles as well as EMI shielding for data protection or laboratory works.
Shielding effect
The EMI shielding effect of our silverized textiles avoids an undesired data exchange and allows uninfluenced laboratory work. Our Shieldex Safety Pouches shield mobile phones, car keys or laptops from the outside world. As a result, our Shielding Pouches support data and theft protection.
Smart textiles
Our metalized products enable the combination of innovative additional features. The excellent properties of silver become connected with the elasticity and flexibility of the textile. This combination is able to stimulate, alert, shine, and be conductive as well as capture vital parameters, temperature, or humidity. Our flexible conductor tracks allow targeted power/ voltage supply, signal transmission, and heat dissipation. They are often used for textile sensors, such as muscle stimulation suits, or for heating fabrics like seat heating or clothing.
Antistatic
An abrupt discharge after walking on a carpet made of synthetic fibers can cause technical issues or total failure in any electronic device. The answer to this problem is our Shieldex-silver-material. Our silverized fibers divert the generated current and have been used for years in many offices worldwide and in the aircraft of various airlines.

Unsere Produkte

Shieldex elecromagnetic shielding EMS
For over 43 years, Shieldex is specialized in the field of electromagnetic compatibility (EMC), producing and distributing shielding materials and EMC fabrics, supplying the most diverse and varied industries.
Shieldex uses only silver with a purity of at least 99% to ensure the best quality standard, as evidenced by various certificates. Our unique combination of polyamide and precious metals such as silver, copper, nickel and tin offers the possibility of multifunctional applications in various fields.
Shieldex® EMC Enclosures
Shieldex® EMC Enclosures are used for RF measurements, mobile forensic activities and pre-compliance testing. These mobile and flexible textile Faraday cages, made of shielding fabrics, can save time and money compared to external facilities. The unique, three-layer shielding effectiveness is up to 95 dB from 0.03 GHz to 16 GHz.
Shieldex Fabrics
As the global market leader in silver-plated fabrics, we finish woven, knitted and non-woven fabrics with 99% pure silver, but also with copper, nickel and tin. A multilayer combination of these metals is also possible. Especially in the field of EMC, the fabrics provide a shielding effectiveness of up to 100 dB in the frequency range 0.2 GHz to 14 GHz.
For our products we exclusively use pure silver with a purity grade of at least 99%. Thus, we consciously distance ourselves from harmful nano-silver.

Shieldex electrical and thermal conductivity
Technical textiles of the future - Made in Germany
Shieldex yarns enable the union of textiles and electronics, giving rise to innovative textile products that can heat, light and be used for electronic sensor applications. With a power resistance of up to <30 Ω/m, silver-plated Shieldex yarns can be integrated into a wide range of applications. Whether for measuring vital signs, illuminating a safety vest in a dark environment, stimulating muscle areas for medical or sports applications, or heating sports and winter clothing. There are no limits to the areas of application, because the combination of textile and technology combines the advantages of both fields.
Yarns & Fabrics - The Right Product for Every Sensory Application
The worldwide unique Shieldex metallization process ensures our and your success. Shieldex products guarantee better conductivity, homogeneous heat distribution and washability of textiles metallized with silver. Customized structures can also be realized with a special process.
High Conductive Yarns
We have developed High Conductive (HC) yarns especially for the field of electrically and thermally conductive textiles and their applications, which rely on a special conductivity of textiles. Due to an increased silver content in the individual filaments of the multifilament yarns and its twisting, we are able to produce extremely good resistance values (up to <30 Ω/m) for an optimal connection with electronic devices.
Partial metallization on flat goods
Our partial metallization technology enables us to map customer-specific, freely selectable shapes of sensors, antenna systems, bus line systems, heating coils and capacitive sensors onto flexible, stretchable material and integrate them into customer applications.

Shieldex antimicrobial solutions
Shieldex prevents odors before they arise
Shieldex technology combines quality, durability and sustainability. The 99% pure silver has an antimicrobial, anti-odor and temperature-regulating effect in the textile. Due to the reduced amount of bacteria, the clothing can be washed less at low washing temperatures. Shieldex textiles are used, for example, in sportswear, socks, bed linen, towels and gloves, as well as cleaning cloths and cleaning utensils. Silver is a biocidal active ingredient according to §67 of the EU Biocide Regulation.
Less is more
Microbes and bacteria are found in clothing, shoes, bed linen and towels. The complex interaction between bacteria and sweat, for example, creates individual (body) odors. To prevent bacteria and the often unpleasant odors from multiplying further, Shieldex offers silver-plated yarns and fabrics.
- Less odor means more confidence - Trust in Shieldex and the unique products that are already improving the lives of many people today
- Less Bacteria Means More Money Saved - The less bacteria on clothing, the less unpleasant odors can occur and the less clothes need to be washed. Save resources and time with Shieldex products!
- Lower temperature means more microbial purity - Lower temperatures can be used when washing. The silver allows the microbial purity of the products to be maintained.
- Reduced pollutants means more biocompatibility - Shieldex products finished with silver are partially Oeko-Tex® Standard 100 certified. Reduced pollutants in the manufacturing process also mean lower CO2 emissions.

Shieldex infrared protection
Protects what matters
Shieldex offers versatile textile solutions for lightweight, flexible and durable shielding of high-frequency electromagnetic radiation (up to 14 GHz) to protect data transmission networks and electronics. Shielding performance can be tailored to customer requirements through the use of various fabric constructions and metal coatings. Shieldex textile solutions provide optimal protection in the infrared range for clothing (uniforms), equipment, aircraft, vehicles and satellites that need to remain invisible to thermal imaging cameras.
Protection from infrared radiation
Shieldex textiles developed for the infrared range are designed to camouflage exactly what should not be visible. The product Shieldex® RS UK IR is already successfully used to camouflage and shield people and objects in the range of mid (MIR) and long wave (LIR) infrared radiation (3.5 - 15 µm wavelength).

Shieldex antistatic
Antistatic - Shieldex fibers
Our Shieldex fibers can be easily blended or spun with natural and chemical fibers, making them particularly versatile in their applications. Due to the conductive property of silver, voltage is dissipated and thus discharge is prevented.
They are used in clothing and home textiles - for example, in carpets to prevent static charge in airplanes or office buildings. Shieldex fibers are available in various lengths and designs.
Our fibers are also incorporated into clothing. In the process, the garment is enhanced by the positive properties of silver. It has an antimicrobial, skin-protecting, fungicidal, temperature-regulating and even odor-inhibiting effect. This combination is interesting, among other things, for neurodermatitis, compression, EMC-shielding, but also for sports or everyday clothing.
Antistatic - Shieldex yarns
With an electrical resistance of up to <100 Ω/cm, Shieldex yarns are ideally suited for static dissipation. The conductive yarn is primarily processed in antistatic screen aprons and shielding braided sleeves.
