Material Technology

"What's inside is what really counts," is a bit of an understatement for the materials of this month's column brought to you by Material ConneXion. From a 3-D printing process to a solid surface, to a woven polyester yarn, these materials use their inner technology to provide an array of applications such as eyewear, flooring and even sculptures.

Woven tape made from polyester yarn and seven tin-plated copper strands. The copper strands "float" in wavy lines along the tape to allow for small amounts of elasticity. The tape contains hot-melt material on the backing that can be heat-pressed or ironed onto any textile and other surfaces. Applications include flat and flexible conductors for automotive, building industry and smart textiles.

Laser-sintering technology for brass and silver alloys in accessory applications. This process creates infinite undercuts on a three-dimensional object. Customization is possible through 3-D CAD data from the customer, and then the manufacturer can provide drawing services to create a prototype. This 3-D concept can be applied on a large scale in metals such as brass, steel and silver without the cost of making a wax mold. The metal parts are available in a 20x20x20 cm (8x8x8 inches) maximum or various single parts of metal which can create larger objects. The metal is available in brass or silver 925, each with various finishes. This process can be applied to accessories/parts for interior design, fashion, footwear, eyewear, furniture, cutlery, lighting design and logos.

High-grade rigid poly vinyl chloride (PVC). This material differs from standard PVC sheets available in the retail market as it is non-toxic, does not outgas (produce fumes) when heated properly, is malleable below 250°C (482°F) and can be shaped, formed, embossed, drilled, sawed and finished in a similar way to metals. Polyvinyl chloride is mixed with additives and formed into sheets, strips and shapes. Although available in one standard white color, pigments, inks and paints can be applied. The material can be finished in a variety of ways and can be combined with epoxies, resin, putties or inlays. Potential applications include jewelry, sculptures, tool handles, buttons and dies for hydraulic forming.

Solid surface created from 80% recycled inorganic materials bound together with a geo-polymer matrix. The manufacturing process has a very low carbon footprint and is able to recycle/reprocess materials at 90% efficiency. Standard slabs are 1 inch (25.4 mm) thick, with 1/4 inch (6mm) being the thinnest possible. Offered in more than 73 varieties of composition and density, the material is non-flammable, waterproof and provides thermal insulation, acoustical absorption and shock/impact resistance. It resists mold, bacteria and pests, while containing no volatile organic compounds, no formaldehyde and being non-toxic. A variety of natural colors are offered, as well as a full range of inorganic pigmentation options. These can be blended for visual variation and patterns. Other thermally stable materials, such as minerals, can be included for aesthetic variation. Powder and polymeric coatings are also possible. Customization is offered in all aspects, density, dimension, aesthetics and functional additions. The un-set slurry can be cast in a conventional mold, or milled and fabricated post casting. Applications include solid surfaces, furniture, flooring, roof shingling, outdoor flooring, consumer goods, acoustical panels, electronic housings and non-load bearing architectural elements.

Print technology and proprietary inks capable of imparting lettering and graphics under the Polytetrafluoroethylene (PTFE, Teflon) non-stick coating of aluminum, stainless steel or enameled steel metal substrates. In addition to the inherent properties of the non-stick coating - long-term durability, high abrasion resistance - custom emotive prints or branding can be incorporated into utilitarian products for the life of the product. Proprietary ingredients including food-grade inks are applied to the mid layer of the three-layer, non-stick coating system, and covered by a clear protective top coat. All layers are transformed from their liquid state into a dry film through a controlled heating and hardening process. Eight different colored inks are currently offered and can be mixed to create additional hues (only food-grade inks are used, so not all colors can be achieved). The thickness of the printed layer, drying time and temperature can affect the final color. The imagery and graphics to be printed are customizable and this process can be combined with colored Teflon coatings also offered by the manufacturer. This coating system and the inks comply with global requirements for food contact materials (NA, EMEA, LGA and Asian Food contact legislation).
