ASTM D4329 testing services available at Micom Laboratories as part of the polymer test services.UV testing is carried out on polymer products or components (for example plastic, fiber glass, painted surfaces.) to assess their ability to withstand UV radiation from the sun for their expected lifetime while also maintaining their usual properties.. To do so, the item could be placed in normal sunlight for a long period of time to examine the effects of the sun on the polymer.

The dimensions for a standard test specimen are as follows: 3’’ wide x 5’’long. Flat and no thicker than 1/8’’ Micom has the capability to accommodate 3-dimensional samples and large samples. If you cannot provide standard samples, our experts will work with you on the optimal approach. We hope these UV Testing FAQs will help you . UV-resistant plastics: some considerations. If a project is to run smoothly, it’s essential that a UV-resistant plastic is used – if, of course, said plastic will be exposed to UV light. If this is not the case, engineers can afford to be less choosy, providing the plastic they choose is suitable for its unique application. .ISO 4892-2 is a standard that specifies test conditions replicating weathering effects on plastic materials through the use of moisture and xenon arc light. Even though ISO 4892-3 is very similar to this method, it differs significantly by the fact that it uses UV fluorescent lights as an illuminating source.

Any plastic jars and beverage containers in your home are most likely made from PET. This material is used in 2-liter soda bottles, peanut butter jars, salad dressing containers and more. While many plastics are only FDA compliant and food safe in their virgin (or unrecycled) state, recycled PET is an FDA approved plastic for food contact.

HDPE Material Properties and Options. Cutting board grade HDPE – meets FDA requirements for direct and indirect food contact, is resistant to hot water, and cleaning chemicals, and will not absorb moisture, bacteria or odors.. UV stabilized grade HDPE – performs well in environments where water, UV exposure, and other harsh elements are present, making it a popular choice .

Ultraviolet (UV) radiation can wreak havoc on traditional plastics, causing them to discolor, weaken, and ultimately fail. As industries around the globe look for materials that can withstand harsh environmental conditions, UV-resistant plastics emerge as a robust solution.
