Subject: Silicone rubber extrusion process - need technical books
From: jvs@interactive.net (Dr. Joseph V. Scuralli)
Date: Sat, 14 Dec 1996 15:49:59 GMT
I need a technical book on the silicone rubber extrusion process which
describes the extrusion process from mixing the silicone to the
extruder, and the curing process using ovens.
Can anyone give me a reference? 
Thanks a lot

A great mesh generator is STRIM from Matra Datavision. Moldflow did an
evaluation of the top mesh generator, and this came out on top. You'll
still need a solver, but don't discount STRIM for meshing.
By the way, STRIM was ranked as the #1 surface modeler by DH Brohn &
Associates and Matra ranks as the #1 provider of CAM worldwide.

I know that RTV is essentially a formulation of poly(dimethyl siloxane).  But what do the 
letters RTV mean?

Dear Netters:
I would like to know if someone has managed to use a
laser printer (rather than a dot matrix or thermal)
on a Waters 990 GPC, with analysis using
Maxima software.  Apparently the company maintains
that no other printer could be installed and that aint
making me happy.
Sincerely,
S. Iyer

Anyone know of an easy way to heat and test different formulations
of Krayton rubber.  The supplier says it will become liquid at 
less than 400 F.  Have tried both pellets and powder.  Just burns
for me.

caution - i once designed a landing gear attachment point that was on
paper twice as strong as equivalent aluminum.  however, the failure mode
involved delamination of a built up thick composite hard point. 
I understand the importance of shear and localized forces. (very
memorable sound when your gear folds underneath you).  don't know how to
model this.  the failure pulled a washer over top of the nut on a 3/8"
bolt, and put a 15 degree bend on the AN bolt.  failure was by slow
delamination by shear.  don't know how to model that!

Try looking into the patent literature. Kodak and others have patents on

Subject: polyurethane windows?
From: austin@midrivers.com
Date: 14 Dec 1996 15:52:45 GMT
About 4 years ago, one of the TV networks/channels ran a story about a guy
who had used a 'bubbling' process to produce/make a thick block of
polyurethane (I believe this was the root material!) that was still
transparent and did not have any visual distortion.  I think that he was
from California and I remember a company's marquis that he had made was
shown outside a building.  The marquis appeared to be at least 4" to 6" or
more thick and was absolutely transparent.  I want to use this material
(chemical process) to make a bell-jar shaped dome if I can ever find the
source.  Will appreciate any leads.  Mike Austin [Austin@midrivers.com or

In thixotropic terms, I believe the property you are intrigued by is 
called "dilatemt."
Just like silly putty, and other PVC plastisols.

I believe "oobleck" was invented by some wizards in a Dr Seuss Story where
the king was tired of only rain snow and sunshine, it fell from the sky
and was green and was a great adhesive.

I second your idea to initiate more specific areas of general interest to 
 subscribers of the newsgroup sci.polymers. Some of the subjects could be 
1) Processing, Structure-property inter-relationships
2) High performace polymers, Specialty polymers, etc.
