Manufacturers will typically add their modifiers and additives and remain tight-lipped about their formulas. They then simply market their product as having more benefits over standard PLA. UV PROPERTIES OF PLASTICS: TRANSMISSION AND RESISTANCE A) benzotriazole-type UV absorber B) benzonphenone-type UV absorber Figure 3: Typical UV absorber molecules. UV absorbers absorb UV radiation and re-emit the energy at less harmful wavelengths. Common UV absorber molecules include (A) benzotriazoles and (B) benzophenones. 2004-05-01 It delivers good stiffness and heat resistance with light diffusing properties. PolyLite™ ASA – PolyLite™ ASA is an alternative to ABS with an improved weather resistance. Its UV resistance and excellent mechanical properties make it the perfect choice for real life application.

The optimal PP/PLA ratio of 80/20 is used to have better film formation in this study based on the results of previous studies. 7, 10, 16, 17 Moreover, MAH is used as a compatibilizer and the optimal parameter of 0.8 wt% is based on our previous study. 18 Finally, rutile‐type nano‐TiO 2 is PLA continuously demonstrated its limitations throughout each exposure. Our test results confirm the supposition that PLA is not durable enough to be used in most consumer products. This leads to the question of how PLA will react to our long-term exposure tests subjecting the materials to direct sunlight, ocean water, soda, and natural compost. resistance to ultraviolet rays can be achieved from polymers extruded by Zeus such as PTFE, PVDF, FEP, and PEEKTM. PTFE has particularly good UV resistance because it has the very strong carbon-fluorine (C-F) bond (almost 30% higher than the carbon-hydrogen (C-H) bond), which is the common side bond It has been reported in the literature that short wavelength UV light (100-280 nm UV-C, and 280-320 nm UV-B) can directly cause degradation of PLA [44] [45][46][47].

This post compares PLA vs ABS and now nylon, and then details how one of these thermoplastics has been augmented to serve a wider range of manufacturing applications. Se hela listan på 3dhubs.com Unmodified types of plastics that are regarded as having unacceptable resistance to UV are POM (Acetal), PC, ABS and PA6/6.

This leads to the question of how PLA will react to our long-term exposure tests subjecting the materials to direct sunlight, ocean water, soda, and natural compost. UV resistance conclusions PLA and acrylic had similar burst strength loss.

Unlike other synthetic fibers, PLA does not absorb light in the visible region of the spectrum; this leads to very low strength loss compared to petroleum-based fibers when exposed to ultraviolet light. PLA is actually the least affected by UV, but you've got the hydrolysis thing so it's a bit of a wash there. Your best best is to paint with something UV blocking for any material you choose. View Entire Discussion (18 Comments) Also, Wikipedia told me that PLA has good UV resistance - so you should be fine IMHO. Here is a good blog post about your question: Using PLA for Long-Term Outdoor Applications.

Since 2011 the import of PLA is more than the exports. The import of PLA in 2016 was worth of US$ 204.79mn while export was US$ 181.55mn.The exports have been increasing from 2011 onwards while an import shows a UV radiation from sunlight is particularly effective in outdoor applications without protection. Main effects on polymers exposed to UV. All types of UV can have a photochemical effect within the structure of the polymers, which can be beneficial or can cause some type of degradation in the material. 2019-10-01 Which Elastomer Offers The Best Weather Resistance?

The huge benefit of PLA as a bioplastic is its versatility and the fact that it naturally degrades when exposed to the environment. For example, a PLA bottle left in the ocean would typically degrade in six to 24 PETG is naturally UV resistant.
