Sipernat 325E is an ultra-fine milled hydrophilic precipitated silica imported from Germany by Evonik. It features high absorption capacity and stable surface area, specially designed for batteries, carrier, anti-blocking and adhesive systems with excellent dispersion and stable processing.
High absorption & loading capacity - Large liquid loading, high carrier efficiency
Uniform particle & easy dispersion - No agglomeration, fit for high-speed lines
Efficient anti-blocking - Good film opening, no transparency loss
Special for battery separators - Uniform pores, better permeability & strength
High purity & inert - Wide compatibility, ideal catalyst binder & carrier
PE/PP separators for lead-acid batteries - Pore former & size regulator
Polyolefin & PVC film - Anti-blocking & opening agent
Powder functional carrier - Liquid loading & anti-caking
Adhesives & sealants - Thickening, reinforcing, rheology control
Heterogeneous catalyst - Binder & carrier material
