[Untited][edit]

Man, I really need help with sorting out these manufactured foams out. Can some chemical engineer or someone who has dealt with foams before please help me out? --flyhighplato 21:45, 14 Oct 2004 (UTC)

Categorization[edit]

IT is noticed that SBR latex foam is not included in this

Wow![edit]

Thats alot of different types of foam you got there. This article was very helpful. Keep this article on here. —Preceding unsigned comment added by 71.204.117.176 (talk) 00:15, 13 September 2007 (UTC)[reply]

Froth, Lather, Foam[edit]

Lather redirects here, but "lather" is not mentioned. The stuff on the cappuccino is froth (I would have said). How about a brief mention of these other expressions? 78.49.79.126 11:33, 26 September 2007 (UTC)[reply]

Introduction[edit]

I've has a go at revising the introduction. The existing one used some very technical terms straight off. I've tried to produce a softer way in for the general reader. I've also mentioned open- and closed-cell foams, because this is an aspect of foams of everyday importance (whereas the polydisperse nature of most foams is not) and one that the reader will be able to connect to via the examples of a bath sponge and a camping mat.

The last paragraph puzzles me. It seems to imply that polyurethane foam, polystyrene foam etc are not actually foams, technically speaking. Is this correct, or is the intention that yes, they are foams, but that they are dealt with in their own articles?

Speed of sound in foam[edit]

The https://en.wikipedia.org/wiki/Foam#Speed_of_sound part is complete bollocks.

It does not talk about the speed of sound at all, switching immediately to a niche topic of hydrostatic power equipment engineering. Even then, the cited frequencies of 1000MHz indicate that the author has no good idea of what he is talking about.

I recommend deletion of the entire content of that section and give links to "speed of sound in composite materials" instead.

Unless objection occurs, I shall edit that section as indicated above.

The 'Foam scales and properties' tab should be removed[edit]

In my opinion, the 'Foam scales and properties' tab in the article should be removed as in my opinion it is pointless having an empty tab in the article. Xboxsponge15 (talk) 21:28, 12 July 2020 (UTC)[reply]
