Precipitated Silica SG-180
GENERAL DESCRIPTION
Precipitated silica SG-180 for use as a white reinforcing filler in the rubber industry...
CHEMICAL DESCRIPTION
SiO2, synthetically produced amorphous silicon dioxide.
APPLICATION
Precipitated silica SG-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 SG-180 can provide vulcanizates of excellent transparency.
APPLICATION FIELDS
Tires, mechanical rubber goods, cables and shoe soles of all kinds.
PACKING TYPES
7kg, 10kg, 15kg, 17.5kg, 20kg, 350kg, 380kg, etc.
STORAGE STABILITY
12 months in normal storage conditions.
HANDING
Consult material safety data sheet (MSDS) for additional handling information for SG-180.
