UV resistance on polycarbonate formulation can be added to the resin or developed as a coating. UV stabilizers are added to polycarbonate to help protect the material from the effects of exposure to the Sun. Radiation from the Sun, especially in the UV portion of the spectrum, degrades the properties of polycarbonate.
If you manufacture a product which contains polycarbonate and are looking to increase the UV resistance of your product in order to give you a competitive edge then contact Advanced Polymer Solutions regarding our patented chemical process we will develop a customized formulation based upon your UV resistance specifications.
Once we develop and thoroughly test the formulation it will become your property which can be patented under your name. APS can manufacture the final the formulation in the desired quantities and supply the manufacturer with a pre-mixed, ready to use coating, additive or adhesive. UV resistance on polycarbonate formulation can be added to the resin or developed as a coating.
UV stabilizers are added to polycarbonate to help protect the material from the effects of exposure to the sun, and indoor lighting.
APS can develop additives to incorporate into the raw material/resin prior to extruding or molding. In this case, the new properties will penetrate the matrix of the material. APS chemists will adjust the formulation to conform to the processing parameters used by the manufacturer. Due to the molecular bond formed by APS' process, the new properties will not migrate and leach from the material over time, even under severe condition.
APS chemists have extensive experience in bonding the same or different substrates together. Materials that are difficult to adhere to are effectively bonded with APS' process.Substrate failure will occur before adhesion failure. In addition, if two substrates with
different coefficients of thermal expansion are bonded, an APS developed adhesive bonding action will not be affected. Such is not the case with conventional adhesives which cannot withstand the varying expansion and contraction of different substrates.
UL Testing - UV Resistance Polycarbonate
A material that is considered suitable for outdoor use has gone through testing in accordance with UL 746C, the Standard for Safety of Polymeric Materials -- Use in Electrical Equipment Evaluations, of ultraviolet (UV) light exposure for 720 hours of twin-enclosed carbon or 1,000 hours of xenon-arc weatherometer conditioning, and/or water exposure or immersion for the seven days at 70 degrees C. The material is tested before and after exposure to these conditions for flammability, mechanical impact and mechanical strength.
The results may lead to one of the following outcomes:
(f1) -- Suitable for outdoor use with respect to exposure to ultraviolet light, water exposure and immersion in
accordance with UL 746C. The (f1) footnote indicates that the material has met both UV and water exposure or
immersion requirements as called out in UL 746C.
(f2) -- Subjected to one or more of the following tests: UV, water exposure or immersion in accordance with UL 746C,
where the acceptability for outdoor use is to be determined by UL.The (f2) footnote indicates that the material has only
met or has been tested partially for UV or water exposure or immersion.
