PVC (Polyvinyl Chloride) membrane is the most widely used tensile membrane fabric. PVC is commonly produced in white, but can be produced in a multitude of colours depending on individual project requirements. When produced in white, this flexible fabric membrane reduces radiant heat gain, keeping interior temperatures cooler in warmer environments. PVC is commonly coated with protective acrylic lacquer, PVDF alloy, 100% PVDF or TiO² coatings. PVDF alloy is made of fluoride, carbon and hydrogen. It has good resistance to airborne pollutants, UV and weather. As the top surface coating is not 100% PVDF it can be easily welded by lap welding.
This material is commonly known as weldable PVDF in today's market and as such it is economical to manufacture and weld. Based on its average self cleaning characteristics the PVC has a design life of approximately 10-15 years. 100% PVDF top coatings offer good self cleaning properties. However, the 100% PVDF coating cannot be welded to another sheet of the same material. The PVDF coating must be ground off or the fabric butt welded. PVC fabrics have excellent fire ratings but are combustible. In general, fire ratings are not a major concern for open structures as the toxic fumes are dispersed by natural ventilation. Based on its average self cleaning characteristics the PVC has a design life of approximately 15-20 years.
When PVC membranes are coated with titanium dioxide (TiO² ) photo-catalyst they inherit self cleaning properties that are superior to conventional PVC coatings. Called the Photo-catalytic decomposition process, a self cleaning action that occurs as the TiO² causes any organic matter (stain or pollutant) to decompose through simple oxidation. The residue does not adhere to the surface and is washed away by water or rain. The Photo-catalytic hydrophilic process, the sheeting action of water across the surface, assures no unsightly streaking is left behind due to water beadi
PTFE (polytetrafluroethlyene) coated high translucency glass fibre fabric is a dynamic tensile material unmatched for its aesthetics and durability, making it ideal for tensile membrane structures and shade structures. PTFE glass fibre coating is chemically inert and capable of withstanding temperatures from -73'C to +232'C. The low-surface free energy of the material results in a fabric membrane which is readily rinsed by rainwater and is completely immune to UV radiation. Under normal conditions, the fabric behaves elastically and does not undergo significant stress relaxation or creep.
PTFE glass fibre high translucent fabric membrane can be spot welded or sewn and provides exceptional strength and durability. These features allow designers the ability to push the envelope of exterior (and interior) design without worrying about cracking or creasing under the strain of repeating flexing or folding. Structurally, PTFE glass fibre fabric is waterproof, resists UV rays and is chemically inert. As a result, it is exceptionally stain resistant and easy to clean. PTFE fabric can reflect as much as 60 percent of visible light to make it a cost-effective, low-maintenance option for building owners and developers who demand a material that installs white and stays that way, long after a project has been completed.
In addition to PTFE's 'non-stick' attributes, when coated with titanium dioxide (TiO2 ) photo-catalyst they inherit self cleaning properties that are superior to conventional PTFE coating. Called the Photo-catalytic decomposition process, a self cleaning action that occurs as the TiO2 causes any organic matter (stain or pollutant) to decompose through simple oxidation. The residue does not adhere to the surface and is washed away by water or rain. The Photo-catalytic hydrophilicity process, the sheeting action of water across the surface, assures no unsightly streaking is left behind due to water beading.
PTFE glass fibre high translucency fabric, is ideally suited for commercial and retail market sectors. By evenly dispersing daylight, this material is a sensible option for facilities such as malls or office complexes, where indoor foliage and landscaping are commonly used. In these interiors, plants grow more naturally without "reaching" toward a specific light source. This material also lends itself well to dramatic illumination. With its highly reflective coating, PTFE glass fibre high translucency fabric serves as a compelling backdrop for night time or interior lighting..
HDPE (High Density polyethylene) mesh is a heavy duty knitted shade cloth designed for tensile membrane shade structures and shade sails where the fabric is placed under large pre-stress. HDPE mesh is suited to large commercial projects where specifications require fabric exposed to environmental conditions including rain, hail, dust and UV exposure. Woven HDPE construction offer maximum ultraviolet protection.
