Hurricane fabric coverings are a newer, relatively lower cost type of shutter. Tested and approved systems are made from polypropylene fibers, polyamide fibers or from laminated or cast PVC. In 2011, a flat hurricane shutter system developed by UltraTek Worldwide was approved by Florida Building Code. [3]
PP: polypropylene, PE: polyethylene, PVC: Polyvinyl chloride, PS: Polystyrene, PET: Polyethylene terephthalate. Susceptibility to photo-oxidation varies depending on the chemical structure of the polymer. Some materials have excellent stability, such as fluoropolymers, polyimides, silicones and certain acrylate polymers.
Kevlar: Para-aramid fibre: High tensile strength: Manufacturing armour, sports and musical equipment. Used in the field of cryogenics: Twaron: Para-aramid: Heat resistant and strong fibre: Bullet-proof body armor, helmets, brake pads, ropes, cables and optical fibre cables, etc. and as an asbestos substitute Mylar: Polyethylene terephthalate film
Kevlar (para-aramid) [2] is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora.Developed by Stephanie Kwolek at DuPont in 1965, [3] [2] [4] the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires.
Polypropylene, highly colorfast, is widely used in manufacturing carpets, rugs and mats to be used at home. [47] Polypropylene is widely used in ropes, distinctive because they are light enough to float in water. [48] For equal mass and construction, polypropylene rope is similar in strength to polyester rope.
Microfiber cloth for cleaning screens and lenses Microfiber mop with Velcro back for fastening on handle. In cleaning products, microfiber can be 100% polyester, or a blend of polyester and polyamide (nylon). It can be either a woven product or a non woven product, the latter most often used in limited use or disposable cloths.
