Hi Phoenix,
Your assumption that S-glass is significantly stronger than E-glass is correct (the AGY website can give you actual values). It is however, much more expensive than E-glass and you will need to factor this into your calculations. As a guide, the S-glass fabric we use is approx 6...
The best material I have used for high temperature insulation is Microtherm (http://www.microtherm.us). The material is rated to >1800°F so 700°F should be no problem.

Prof. Jon Binner at Loughborough Universtiy in the UK is extremely well regarded in the field of microwave sintering and should be able to help you. See http://www.lboro.ac.uk/departments/iptme/staff/jgpb/index.html for further details. If Jon can't meet your exact requirements, he will almost...

Paisan,
The effect of porosity depends on the size of the pores, the temperature and the thermal conductivity of the material in question.
The optimum insulation material will depend on the temperature range you are interested in. If you can supply more details e.g. application...
Have you thought of using a woven glass scrim? You may need a hydrophobic finish to protect it from steam damage which can occur at surprisingly low temperatures in the right/wrong conditions (we have seen it as low as 200°C)but otherwise temperature should not be a problem.
The main glass...
Rembrandt/rustbuster1,
Thanks for taking the time to reply to my question. To clear up a few areas where I was unspecific, the paint/coating I am looking for would be applied at ambient temperature and exposed to 200°C in service in a clean room environment. The paint is to be used to cover an...
Thanks for the reply YM. Unfortunately, the application for which I am looking to use high silica fibres cannot possibly support the cost of quartz fibre. The fibres are to be used as a high temperature reinforcement for composites (hence the desired small diameter) so I would be more...
There is loads of product data on the Rockwool website, www.rockwool.com. If you can't find what you are looking for on there, the research labs in Denmark should be able to help you out.
Have you tried Microtherm at www.microtherm.uk.com. The thermal conductivity of their material is comparable to PU foam at low temp and the density can be increased to improve compressive strength if needed.

I'm looking to improve the dispersion of e-glass filament in a water based emulsion. Can anyone recommend a dispersant/additive which could prevent the filaments from clumping together?
Thanks in advance

Try Amcor flexibles in Thetford, DuPont Teijin in Middlesborough or Wipak in Walsrode, Germany. They would all supply aluminised film/barrier materials but I think you may struggle to get anything 100 metres wide (typical roll width is 3.2 m).

Rockwool is a trade name for a type of mineral fibre insulation made by, would you believe, Rockwool. Their main site www.rockwool.dk is very comprehensive and should contain most of the info you are looking for.
