Kann man mit IPA vielleicht EVA desinfizieren?
In dachte ich noch, das Zeug wäre aus Polyurethan, aber die sind laut Lieferschein aus EVA (Ethylen-Vinylacetat-Copolymere)…
Liegt der Verschleiß (ein Paar Stiefel hält etwa 500 bis 1000 Stunden) auch am IPA (Isopropanol) oder allein an der mechanischen Belastung (die gehen oft in die Hocke und an der Ferse und am Spann sind meistens die ersten Risse)?
Wirkt eine 80%-ige IPA/Wasser-Mischung überhaupt bei Zimmertemperatur, wenn man sie immer wieder mit einem Stiefel in/über den Anderen schüttet? Also einfach so ohne rubbeln/bürsten…?

The optimal disinfection effect has 70% isopropyl alcohol. EVA with closed cells is not the best material from wear resistance. There are absolutely rubber boots which are more durable, e.g. those made from PVC, nitrile rubber or chlorinated rubber. For example, this one: Dunlop “Acifort” .
Yeah, I know, but my employees can’t come with PVC… they want to create a family, and only because of the money…
or is there PVC without plasticizer?
how does it look with nitrile rubber and chlorinated rubber?
or should you ask a new question?
The plasticizers you mean have been banned for many years. PVC without plasticizer is not elastic but brittle. Let a company advise you or inform you on their websites. for example at Dunlop. You can also contact the professional association. In addition, employees are not entitled to certain materials if the boots meet the requirements of the BG. If they don’t want them, they have to buy themselves and pay for themselves.
The boots are on the floor and not in the food! The most clobular I know are the winter boots for construction with steel cap and steel sole, which are yellow.
For the food sector, for example, these are recommended here from PVC:

Steel cap doesn’t need anyone here or are they more clobster?
PVC seems to be more stable, but food-real it is not… Keeping cans are more of PE and PP…. right? PU and EVA would also be fine…
Then you must select boots intended for food processing plants, which are usually white but also often made of PVC. This is available with or without steel cap and penetration-proof sole.
I’d rather not want visitors… at the earliest tomorrow, if there’s no shooting…
it would just have to be real food (they stand in there for hours with naked feet) and clobig look…
Certainly, there are also wholesalers especially for workwear and safety articles. Some even have representatives who come to the company and introduce their assortment.
yes… ok… I want to get out of the way as far as possible… and buy as cheap as possible… so equal to 50 pairs in different sizes… I also know now what we need more… that will definitely give discount to some dealers…
What exactly do you want? According to the header of the question “disinfect”, but according to the text “impregnate” ….
First: With IPA, you can naturally disinfect, so you probably think: eliminate odor. There are also sprays.
Secondly, impregnating/fatting/smoothing is a science itself, even home recipes are partly good. The durability of the plastics of shoes depends on the manufacturer. I still have super nice Nike shoes that are ill 30 years old! But I had to repair them several times with special adhesives from UHU and also with PU, which you don’t see, they look like a year old.
Life Tip: For each repair, knowledge about chemistry, building materials, materials and overall All-rounder experience of advantage. The more you learn, the cheaper and more interesting it lives!
where is “impregnate”?
Are you stressing your Nikes 50 hours a week?
No, just in the gym, so 3 x 1.5 hours a week. These shoes are very special. Two times Africans wanted to buy me them! Once in Amsterdam, once in Rapperswil, which made me of course particularly well-maintained … but my favorite jogging shoes from Reebok have been completely and irretrievably broken after 4 years, the inner foaming material shredded so much that the form of shoes suffered, which were unrestorable, and cost a fortune. Currently, I still have favorite shoes from Under-Armour, as light as a feather, no longer to get, so they only rarely wear them…
cool…
yes: Foam does not seem to last long…
