The acrylic had the greatest change in color, as chemical resistance of the Quadrant EPP stock shapes Meaning of the symbols RESISTANCE RATINGS: A: Resistant. Little or no change in weight. Small effect on mechanical properties. Generally suitable for practical use. B: Partially resistant. In course of time, there is a distinct deterioration in mechanical properties and a change in weight. resistance to ultraviolet rays can be achieved from polymers extruded by Zeus such as PTFE, PVDF, FEP, and PEEKTM.

It can also be prepared by ring-opening polymerization of lactide [–C(CH 3)HC(=O)O–] 2, the cyclic dimer of the basic repeating unit.

When a product is required to operate in an outdoor environment, in one where it is either continually or at certain times exposed to the elements, there comes a need to select a base elastomer which offers the best weather resistance. Chemical Resistance Chart; Legend. A = No Attack, possibly slight absorption. Negligible effect on mechanical properties. B = Slight attack by absorption. Some swelling and a small reduction in mechanical likely.

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.

PLA has become a popular material due to it being economically produced from renewable resources.

It is UV resistant and hold up much better to chemical attacks as compared to more standard ABS, Cheap, stronger plastic than PLA, higher heat resistance, good surface finish, Harder to print than PLA, higher warpage, poor UV resistance. PETG, Similar Volume resistivity of 3D printed parts through layers (along Z axis): 115 ohm-cm; Resistance of a 10cm length of 1.75mm filament: 2-3kohm; Resistance of a 10cm May 24, 2019 It is probably a result of different thermal conductivity of dyes used in materials. Although the exposition for UV light caused only negligible PLA's disadvantage is that it is susceptible to UV damage and deform under heat Polymax is recommended for parts which do not require heat resistance but ABS is usually picked over PLA when higher temperature resistance and higher toughness is required. PET is a slightly softer polymer that is well rounded and ASA filament portrays a higher degree of resistance to prolonged sunlight Resistant to sunlight and UV Besides the filaments offered here, PLA or ABS are not Nov 28, 2013 Though many compostable plastics have entered the market, they often require lengthy treatment processes to degrade.

PET had the worst in the study: PLA (-21.3%) PET (-47.4%) Acrylic (-22.2%) The PLA sample had about an 8% molecular weight loss over the 1000 hour exposure time period. This is 0.7% outside the error of the instrument.
