Hypalon is a patented technology for sulfonated neoprene polymer. Hypalon is also a Reg. Trademark. There are many alternatives but good old neoprene wasn't bad. There is a mill in MA that sells a sulphur stabilized neoprene. Urethane encapsulated polyester or nylon is the next best fabric option.
The Chinese will tell you its Hypalon but they have not a clue to the crap they are selling; ditto for their PVC; whadda ya gonna do.... litigate it in CN or just not buy from them.
Hypalon was abandoned for a reason, there is no money in it.
