After more than two decades of field exposure in different climatic conditions, samples collected of EPDM membrane show no evidence of crazing or cracking. As a result of the excellent UV resistance, EPDM membrane can be warranted up to 30 years. Does ponded water have any affects on the performance of EPDM membrane? Since its infancy, when EPDM was used primarily for pond lining and canals, it has demonstrated excellent resistance to moisture absorption. See similar questions...

No. That is why, after application of Dr. Fixit Torchshield, all non-foot-traffic areas should be finished with aluminium paint for UV protection See similar questions...

Copolymer and homopolymer acetals are very similar in many characteristics. However, there are some differences, e.g. TECAFORM AD (POM-H) has higher mechanical values, better wear resistance and is better for use in tribological applications (friction and wear). TECAFORM AH (POM-C) has better chemical resistance. See similar questions...

UV radiation is commonly used in germicidal lights in hoods and is a component of sunlight. UV radiation will have a serious deleterious effect on most plastics, especially the polyolefins, including polyethylene (low-density polyethylene [LDPE] or high-density polyethylene [HDPE]); polypropylene (PP), and polymethylpentene (PMP); and acrylics. Polystyrene (PS), polycarbonate (PC) and polyethylene terephthalate G copolymer (PETG) can withstand limited UV exposure. See similar questions...

No. You should always paint or cover foam that will be exposed to sunlight. UV rays will cause the foam to discolor and degrade. Touch 'n Seal Black Foam is UV-resistent and does not require painting to maintain it's integrity. See similar questions...

Yes, the formula includes a UV inhibitor. The product was formulated for the New Zealand market where the ozone layer is thin, allowing more UV through than we find here in the northern hemisphere. See similar questions...

Standard CDA cases are slightly UV-resistant. In additiona, they will protect your items by sealing them in hard acrylic to keep them in the same condition as when they were graded. They will not be touched by human hands and the hard acrylic prevents it from sustaining any additional creases, bubble dings, or other damage. In addition, 99% UV-Resistant acrylic cases are available for additional light protection. See similar questions...

Most of the decals are not resistant to UV light. If UV resistance is required for the decal, you must state out this condition when you make the enquiry. The material and the ink for the decal will be different. And the cost of the decal will not be the same. See similar questions...

Most of the stickers are not resistant to UV light. If UV resistance is required for the sticker, you must state out this condition when you make the enquiry. The material and the ink for the sticker will be different. And the cost of the sticker will not be the same. See similar questions...

U.V. acts as a strong catalyst for the oxidations process which breaks down the polymer chains, leading weakness in the pipes & fittings and to loss of hydrostatic strength." Above effect is very much possible with materials like PP & PE. But for PVC main process is dehydrochlorination not Oxidation. This dehydrochlorination does not break down the polymer chains to any significant extent after outdoor exposure, being mainly limited to a surface discoloration effect only.

Ultraviolet (UV) light is at the invisible, violet end of the light spectrum. Even though we can't see UV light, we are exposed to UV rays from all light sources, including the sun. See similar questions...

EPDM (Ethylene Propylene Diene Monomer) is an organic synthetic elastomer which, when cured, has many properties equivalent to or better than those of natural virgin rubber. During the production of the EPDM polymer, there are several additives which are used to enhance color stability, wear characteristics, durability and flexibility. The original state of this EPDM is actually scrap derived from the manufacturing of virgin EPDM. See similar questions...

Like any decorated products, direct sunlight will cause sublimated products to fade over time. Factors that affect fading are temperature and weather - for example an area with more direct sunlight and dry, arid conditions will probably contribute to faster fading. With that being said, the ArTainium2UV+ inks are specially designed for longer UV resistance. See similar questions...

They have a limited resistance against UV light. Whereas the proportion of UV light within daylight does not harm the material, exposure to special UV lamps will damage the material and lead to discoloration. Therefore, we do not recommend disinfecting MixMate via UV irradiation; please use alcohol-containing disinfectants instead. See similar questions...

EPDM is a synthetic rubber polymer made from ethylene and propylene monomers. It was developed in the early 1960's and is used in radiator and steam hoses, freezer gaskets, tires, roofing membranes and aircraft seals to name only a few applications where EPDM is superior to other materials.

All light is given off at different wavelengths. For example if you see a rainbow, you will notice that the colors are always in a specific order from red all the way to blue. You are able to see each color due to their individual wavelength. These wavelengths are part of the visible portion of the electromagnetic spectrum. UV light is at a wavelength of 254nm (nanometers), and is not visible to the naked eye. See similar questions...
