Hey CEans,
do you have any idea about how we are obtaining polychloroprene sheets for wet suits (or neoprene) after having made the polymer?
I have found a website that describe a little how to do it,
http://www.aceraft.com/mediapg/medapg32.html
They said : "
Neoprene is often referred to as 'rubber' but it is actually a plastic. It begins as a powder called polychloroprene. To this base are added other ingredients that provide elasticity, foaming agents, cell size, colour (usually black), adhesion, bulk, plus other properties. This mixture is made into a dough which is plopped into a heated press. Under pressure and heat the mixture squishes out to make a sheet about 90" by 53"."
but I would like to know a little bit more: not what is added, it's a secret, I understand, but which pressure, temperature, how lob does it take...
It's for a project I have to do in my engineering school. I still have to do a part on a process.
Can you help me?
Thanks
