AI Thread Summary
The discussion centers on concerns regarding the safety of a hydration bladder that lacks clear labeling about being BPA-free. The user notes that the product, made by Guangzhou KMS, is constructed from TPU (thermoplastic polyurethane) and EVA (ethylene-vinyl acetate), materials that are often used in hydration products. However, there is uncertainty about the safety and potential health implications of these materials, especially in comparison to BPA-free alternatives. The bladder does not have any stamps or markings indicating its safety or material composition, which raises questions about its suitability for long-term use. The user is seeking more information about TPU and EVA, as well as the general standards for hydration bladders regarding BPA and safety labeling.

I was just given a hydration bladder:

https://www.amazon.com/dp/B00JY9WFO2/?tag=pfamazon01-20

But NOWHERE on the package does it say it is BPA free. Almost every product now says it is BPA (Including glass jars which I find to be redundant.) free. Another website says it is made out of TPU and EVA. I don't know much about this stuff. I thought that perhaps you guys might know something.

Thank you!

What about a stamp on the bladder itself?

All there is on the bladder itself are; a measurement line on the side to tell me how much water is in the bladder, and various pictures under the forward slash symbol to tell me what I can't put in it. Do you know anything about TPU and/or EVA?

No. I was looking around, but nothing definitive. Some have it, some don't.
 

Thread 'Humidity of a saturated NaCl solution with anticaking additive'

I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...

Thread 'Resists for etching Aluminium with NaOH'

I'm trying to find a cheap DIY method to etch holes of various shapes through 0.3mm Aluminium sheet using 5-10% Sodium Hydroxide. The idea is to apply a resist to the Aluminium then selectively ablate it off using a diode laser cutter and then dissolve away the Aluminium using Sodium Hydroxide. By cheap I mean resists costing say £20 in small quantities. The Internet has suggested various resists to try including... Enamel paint (only survived seconds in the NaOH!) Acrylic paint (only...
