Product Features

• We mainly supply for printed circuit board etching, and polymerization of synthetic rubber and resin, such as Styrene butadiene rubber, Polytetrafluoroethylene, etc.
• We use sealed equipment to electrolyze in order to prevent metal contamination. This makes our products have lower impurity levels than those of other manufacturers.
• We can supply in packaging according to the user’s request. (25 kgs., 500 kgs., or 1000 kgs. bags).

Main Applications

• Printed circuit board (etching)
• Synthetic resin (polymerization)
