Product Overview
We are engaged in exporting excellent quality Cobalt-Free Color-Changing Silica Gel (Orange Silicone) in Tangshan, Hebei, China. Cobalt-free color-changing silica gel (orange silicone) also has the performance of changing its own color after absorbing moisture, but compared with silicone, because it does not contain cobalt chloride (in 1998 the EU identified cobalt chloride as Class II carcinogen), it is more suitable for customer's use.
