Acetyl Material

[Danger Phoenix]

I am doing a project on a robotic hand, and it says it uses Acetyl as a material... I have been trying to research this, but all I keep coming up with is chemicals - does anyone know what it is?

Thanks in advance

that is particularly vague - an acetyl group is CH3C=O but it has to be attached to something.
Saying acetyl on its own makes no sense - it must be a tradename for something.

Maybe there's a spelling mistake and it means acetal (aka Delrin I think)?

I use that for worms and muffs in my models.

 

[Danger Phoenix]

Its definitly not a spelling mistake because it is mentioned many times...

 

[aardvark]

in the same way, saying acetal makes no sense on its own

 

[Mr Joshua]

Yeah but you get more relevant hits on ebay for acetal!

 

[Danger Phoenix]

lol!

Well, if it is any help, I am talking about this:

seems likely that it would just be an acetyl based plastic that has been moulded with. Only explanation for its random use in the materials.

looks like it - it doesn't seem critical so you could any suitable plastic.

as for what the plastic actually is - it could any of tens of thousands of different polymers from that descrption!

Worms and what?

 

[Mr Joshua]

Muffs...

The wheels are on a split axle so they need to be joined by a bit of plastic tubing called a muff. The gears are mounted on one which has been turned to leave a lip seperating the two. Both worms and muffs in that picture are made from acetal.

 

[Defcon5]

Suppose its a good excuse when someone finds muffs in googles search history!

you make muffs ? good lord...

 

[Mr Joshua]

No, I buy them!

 

[locutus12]

No, I buy them!

aha! good old prostitution.

Acetal is similar to delrin which is similar to nylon iirc

Read as hardish plastic that you can carve, machine etc.

Edit: Danger P just noticed it's your post, hello matey, how's things at uni?

 

[locutus12]

iirc

ive been on the net for 11 years and still i have no clue what that means...

Hehehe, "If I recall correctly"
