Precipitated Silicon Dioxide As White Powder Used For Rubber Industry
GENERAL DESCRIPTION
Precipitated silica HF-180 for use as white reinforcing filler in the rubber industry.
CHEMICAL DESCRIPTION
SiO2, synthetically produced amorphous silicon dioxide.
APPLICATION
Precipitated silica HF-180 has high reinforcing potential and imparts to rubber compounds high Shore hardness, tensile strength, tear resistance and abrasion resistance. In order to achieve optimum rubber-technical data the addition of activators like glycols, amines or other alcaline accelerators is necessary. On account of the higher surface area precipitated silica HF-180 can provide vulcanizates of excellent transparency.
APPLICATION FIELDS
Tires, mechanical rubber goods, cables and shoe soles of all kinds.
PACKING TYPES
10kgs/bag.
STORAGE STABILITY
12 months in normal storage conditions.
