Need advice for vulcanizing shore A-70 rubber.
(OP)
I need to know how much I shall use of each part of natural rubber and sulphur in order to make vulcanized rubber with a hardness of A-70. Also interested in which temperature and heating time.
Are there any good online stores where I can buy natural rubber and sulphur in small amounts for testing it out?

For samples I suggest you contact a friendly rubber company nearby, as you were advised to do in answers to your earlier 2011 enquiry.
