The EN process allows for uniform plating thickness on not only metal objects, but also plastics and ceramics. SHP may be used as a reducing agent or antioxidant in chemical processing, also may be used as a partial fire retardant. Package In 25kg kraft paper bag, or 500kg supersacks, total 20mt/20’FCL palletized. Kindly contact us at kaihope at pekchem dot com, thank you.
