we are preparing a sample for a molded float in ebonite expanded capable of supporting a force of 1500 N m/sec.

May I ask any advise about the filler and the percentages to add for preserve the strengths inquired.

RE: mould ebonite expanded

I've only ever worked with solid rather than foamed ebonite.  It is very brittle having a very high modulus and low elongation at break.

RE: mould ebonite expanded

(OP)
Our objective is to decrease the specific weight to allow the floating on liquids. the pure ebonite has a s.w. between 1,1-1,2 but if expanded the s.w goes down 1.
Otherwise for reduce the brittling we are adding 20 parts of ebonite dust on 100 of nr.

thanks for your reply
