![]() This causes the film to light up quicker than prismatic tapes and makes it visible at greater angles. (Floodlight vs Spotlight) Because of this wide dispersion of light, engineer grade returns about 30% of the light back to the source with the rest being dispersed around the target. For example, firemen like Flex EG films and use them to wrap their tools for easy identification.Įngineer grade films reflect at about 75-85 candelas and return light at wider angles than prismatic tapes. This quality makes it perfect for graphics applications where films need to mold over uneven surfaces or wrap around very tight diameters. ![]() We carry a special "Flexible" Engineer Grade which features a polyester topcoat making it much more flexible, conformable and stretchable than "Standard" Engineer Grade. Type 1 films have no pattern, just a nice smooth solid color which makes engineer grade popular for vehicle graphics and signs as well as thousands of other applications. Utilizes high index glass beads dispersed evenly on a thin flexible film to create retro-reflectivity. Flexible Engineer Grade (Type 1) - Our most popular and affordable reflective tape. All of our tapes (except sew on SOLAS) are self-adhesive or peel and stick.ġ. Self Adhesive - Having an adhesive backing protected by a release liner until ready for use. Yellow is vivid, which is why it is used for yield signs and school buses. Red is vivid, which is why it is used for stop signs. In common terms, it would be how much a color stands out in regular light. Involves factors such as saturation, or color intensity. Vividness or Chromacity - the quality of color, independent of how bright or reflective an object or film is. A blade is used by the machine to cut through the film and leave the release liner intact. Photometrics - The measurement of the intensity, brightness, or other properties of light.ĬAD or Plotter Cuttable - can be cut into shapes by a computer-assisted design program and a plotter. T he base unit of luminous intensity in the International System of Units that is equal to the luminous intensity in a given direction of a source which emits monochromatic radiation of frequency 540 × 10 12 hertz and has a radiant intensity in that direction of ¹/₆₈₃ watt per unit solid angle. Some reflect in a wider beam and can be seen closer in but at great angles.Ĭandelas - A unit of measurement used to compare the brightness of reflective surfaces. Some tapes reflect in a tight beam and can be seen at great distances. Light Dispersion - the width of the returning beam of light from a reflective surface. Light is collected and concentrated back in the direction it came from. Retro Reflectivity - the ability of a tape to return light back to the source of that light. Choosing the right reflective tape involves considering all factors which include the surface the tape will be applied to, the light dispersion and brightness needed, the colors that best suit the application, and the distance the tape needs to be seen both day and night. (Our "specialty reflective tapes" will be discussed in a separate article.) The goal of this article is to help you select the tape that is best for your job. This post will briefly discuss each type of "standard reflective tape" that our company carries. These are all factors to consider when selecting which type of tape to use for your application. Reflective tapes vary in flexibility, durability, vividness, color and brightness. Ten Types of Reflective Tape - Deciding Which One is Best for You.
