How Many Types of TGIC Curing Agent in China?

There are over 20 manufacturers of TGIC curing agent manufacturer in China, while the types of TGIC curing agent just has two type. One is noodle shape as the pic-1, another is semicircular as the pic-2. 

Both types have their advantage and disadvantage. For the noodle shape shape, it has dust which, but good dispension in the resin when extrusion. For the semicircular no dust, but bad dispension in the resin when extrusion. While both types have their own cusomers, it seems it depends on Customers choice mainly. 

From my standing point, I prefer the type from Sun chemical Type TGIC-G, which take the advantage of both noodle and semicircular. It is granular shape, avoid too much dust, and keep good dispensing ability.

And because of TGIC curing agent in China is viewed as the environmentally unfriendly have been added to the government's list of production capacities to be phased out, so the permits for the construction of such factories are no longer being issued.
