Re: [PSUBS-MAILIST] Syntactic Foam

Back on the syntactic foam thread for bit; can anyone recommend a good supplier for the components of syntactic foam?  I plan on using syntactic foam on the aft of my boat to offset weight of equipment to gain longitudinal trim.  My understanding is that syntactic foam is made up of hollow glass microspheres for buoyancy and some type of epoxy as a binder. This implies to me that varying the amount of each can be used to get a range of densities and strengths in the finished piece.  Does anyone know of a manufacturers web site that will give this kind of data?  Because my boat is rated for 300 fsw, I need a relatively low density ( 20 lb/ft^3, SG=0.32) and not a lot of compressive strength as compared to foam being designed for 10,000 fsw.
 
Any of you foamers have suppliers you are happy with?

No worries Bob, you were also correct, some Syntactics are thermoformed with various plastics, but the equipment
and tooling required are quite expensive and out of the range of most us backyard builders.

Hi All! I am so sorry for leading everyone astray on the 300 -400 degree curing temp of Syntactic Foam.  I swear I saw that on the Cuming Corporation Web Site http://www.cumingcorp.com/index.html , but, I just poured over it again and, well, I must have been seeing things or dreaming. Please forgive me for posting incorrect info. Bob Teufel
