A most useful material. If you got this from me by BCC then
you want to look at the usage guide if you don't know about
it already.

______________________


A low melting temperature plastic worth knowing about for
engineering playing.
Can be softened with hot water then moulded to harden back
into a reasonably robust plastic.
May not be dishwasher safe ;-).

Sold in pellet form by various suppliers. (Jaycar in NZ).

Can be used to take some very evil shortcuts. Will tempt you
to new heights of lashuppery.
The usage guide is an eye opener.
Wiki page interesting but less useful.

As a dedicated bodger of all things I thought you might be
interested in
polymorph pellets (aka polycaprolactone and in the US known
as Friendly
Plastic).  Jaycar/Soanar/Electus stock them in 100g bags
(product code
NP-4260) and describe them thus:

"Polymorph will change the way you make parts. It's a
commercial grade
thermoplastic that softens enough to be formed into any
shape at around 62 -
65° C. You simply heat the pellets in hot water or with a
hair dryer. It
hardens at room temperature to form a tough plastic material
similar in
consistency and colour to Nylon. It can be drilled, sanded,
ground, machined
or heated and reformed again and again. Endless uses in
model making, craft,
single part manufacture, prototyping, engineering, science,
lab, clinical
applications and more."

The Wikipedia knows:

A usage guide is available here:

I've got a big tub of this stuff and its great (when you remember that
you've got it).

I've made CCTV brackets, motor mounts, strange shapes and all kinds of other
interesting things with it. Its also very handy for filling in small gaps in
an emergency.

As far as toughness goes its extremely tough when hardened/cooled.

Best thing about it is when you cockup what you're making you just reheat it
and try again.

I've been told that it gets brittle with age, though.  Some costumer  
made a set of hooves, and they didn't last...

How big is a "big tub" and what brand name is it. It may be
available here at a better price than the 100 gram packs I
am aware of so far.

I bought a 500g tub from Maplin in the UK for around £10 ($20usd) when they
had it on special offer.

Mayhaps a "tempering" occasionally may help - raise the
temperature somewhat to near but below where moulded details
are lost.

That would hurt if it was volatiles that were being lost.

Have a look on ebay. Someone there seems to be selling the same product
line that is available on mutr. Prices seem reasonable.

>> better price

This stuff is a "material of choice" for the homebrew 3D-printer  
community.  See for instance the reprap info here: http://reprap.org/
bin/view/Main/Polymorph

And the (*the* !) current manufacturer seems to be here:
http://www.perstorpcaprolactones.com/products/product_line/0,0,-
_EN-33,00.html

As is the case with many "industrial supplies", I didn't see any  
sites catering to the "mid-sized" customer who might want to buy one  
20kg sack every year or so.  It's rumored to get down to about $10/kg  
in that quantity (direct from the *previous* manufacturer?)

I'm told it is about half the Maplin price at Rapid.

http://www.rapidonline.com/searchresults.aspx?style=0&kw=polymorph seems to
find it, but in smaller amounts.

If I buy 10 x 100g from a local wholesaler it's about $NZ60
or about GBP25?.

Not too much dearer in single 100g lot.

whatever its called these days.

There were links (albeit, screwed by formatting) in my message
referencing the reprap site.  Here:

$40 for 28oz.

Hey man, we americanistos are the top of the food chain.  It is a  
brit that should do the search for me.  And take a bullet for me if  
that is what is called for.  I have gradually seen furinuurs take  
over this list and it just ain't right.  My leader Jorge Bushcado say  
so.

Cedric,

We need to foster this approach.
As long as we can continue to let them let us filter their
information through our filters we will be able to continue
to rule the world without them knowing.

I was just about to ask what the original language was, so that I could put

<F_level = /CedricChan;/Damn_Yankees>

I think it's an emerging dialect - a patois of 'damn yankee'
and 'ugly american' with perhaps a hint (hardly visible
here) of 'pax americana' thrown in. No hint of motherhood or
apple pie here. Sea to shining sea also seems absent.

</F_level = /CedricChan;/Damn_Yankees>

Who can tell?
