We provide the cleanroom industry with a range of reusable protective apparel and related materials (designated ChemStat®) that are designed to reduce microcontamination and stray voltages. The cleanrooms may be electronic, pharmaceutical, aerospace, or automotive) paint related. In addition to the primary garment material, the ChemStat® line includes face mask material, reusable nose bridges, and static dissipative soles. These are generally polyester fabrics and nomex fabrics that are static dissipative.
Woven of 100% Nomex fiber, our ChemArc® fabrics meet the latest requirements for arc flash protection in a range of 4-12 cal/cm2.
The aerospace industry places a premium on weight reduction. Consequently, many of our products are high-strength-to-weight materials.
Some aerospace fabrics are used as aircraft interior products and are composed of heat resistant materials. Some are inherently static dissipative or electrically conductive.
Stern & Stern works closely with NASA and its subcontractors to produce new materials for new applications as NASA's designs evolve. Our materials are used in space suits, cargo bay liners, and protective apparel for ground personnel. These are generally Nomex fabrics or Teflon fabrics. Custom parachutes for interplanetary missions use ultra-light nylon fabrics and polyester fabrics.
We are a leading producer of two and three dimensional Teflon fabrics, suitable for incorporation in load-bearing laminates that require no lubrication. Typical examples are bearing fabrics that are used to line journal bearings on control surfaces (such as ailerons and rudders), or seismic isolation systems.
Filtration is used to extract either valuable or pernicious elements from either a dry or wet fluid stream. Fabric strength, permeability, and chemical resistance are key design elements.
Elastomeric Substrates, Coated Fabrics:
When an elastomeric is heat cured on a thermoplastic substrate, a physical mismatch can distort or degrade the original physical parameters of the woven substrate. Our unique processing methods match the physical properties of the substrate to the process conditions in coating for optimal performance or yield. Coated fabrics employing Stern & Stern's substrates are incorporated in many aerospace and automotive applications.
To prevent dehydration in burn patients, we manufacture woven fabrics that simulate the permeability of human skin. Careful processing minimizes broken filaments that would otherwise adhere to tissue regenerating in the wound. Other fabrics designed for extreme pliability are similarly processed for use in plastic surgery.
We produce fabric substrates for specialty belts, easy-tear tapes, and splicing tapes. These substrates involve either the control of a woven pore size or the weaving of materials vastly dissimilar in terms of strength or elongation.
Mil-Spec fabrics are fabrics designed primarily for military or related uses and are accompanied by a corresponding specification. We produce Mil-C fabrics composed of nylon, polyester, Nomex, Teflon, and Kevlar in a wide range of weights, strengths, and permeabilities. Recently, specification control of parachute-related Mil-Specs has been transferred from the US Military or its subcontractors to the Parachute International Association (PIA) and many former Mil-spec fabrics now carry a PIA-Spec designation.
When resin systems or elastomerics are combined with reinforcing fibers, exceptional properties can be obtained. The resin or elastomeric matrix spreads the load applied to the composite between each of the individual fibers and also protects the fibers from damage caused by abrasion and impact. High strength and stiffness, ease of molding complex shapes, high environmental resistance all coupled with low densities, make the resultant composites superior to unreinforced materials for many applications.
Our fabrics are used in both elastomeric and rigid resin laminate construction, either as a substrate material or as multi-layer elements. Some composite laminates even involve woven Teflon fiber, which one does not normally associate with laminates or adhesion; however for flexible or rigid composite use, we are able to produce woven substrates from any fiber.
