What is the best membrane for your application ? A. A VAC-SIL® Membrane of course - but this is a really vital question. There is no one answer that is right for everybody. There are many factors that can effect the choice of membrane for example :- - type of encapsulant (eva etc.) - make up of p.v. / solar module - type of laminator - operating cycle – time/temperature - budget constraints We would be delighted to discuss your own specific requirements further. Q. How long should a membrane last? A. This is really very subjective as operating conditions and controls can be so very different from company to company. For example we have one very large European customer who has modified the encapsulant used and strictly controls their production process - so much so they achieve over 10,000 cycles using our standard VAC-SIL PRO® Membranes. Typically we are suggesting :- VAC-SIL PRO® - 2,000 cycles + VAC-SIL LAMI-FLEX ® & LAMIN8 - 5,000 cycles. As there are a number of variables beyond our direct control, it is very difficult to “guarantee” an exact cycle life - however, J-Flex will always be fair with our valued customers. Q. What can be done to extend the life of membranes? A. A whole host of things can be done including - correct fitting and tensioning; regular maintenance checks; regular cleaning of eva deposits. In addition you could protect the membrane with a layer of PTFE / Fabric release sheet between the modules and the membrane. (We do have stock options available – just talk to us). If you need eva resistance our VAC-SIL LAMI-FLEX® or VAC-SIL® LAMIN8 Membranes have great resistance to outgassing and give far better life than standard membranes.
