PPT Silica/SiO2 Silica Powder for Silicone Nipple
Model No.:JS-185C2
Apperance:white powder,tasteless
CAS. NO.:7631-86-9
Usage: as filler for silicone nipple
Unreinforced silicone rubber has a strength of only 03MPa and can hardly be used. In order to reach the level of practical application, it must be filled and modified. Common inorganic powder fillers include calcium carbonate, precipitated silica, fumed silica etc.PPT silica is a good choice.
How can the ppt silcia filled silicone products?
1.Rubber is adsorbed by filler particles to adsorb polymer, so that rubber molecular chains are directly fixed near the filler particles or are directed along the filler surface or retained by filler aggregates.
2.Rubber and filler particles combine filler particles with polymer segments to produce effective crosslinking and polymer tangles filler particles
3.Rubber and filler particles combine filler particles with polymer segments to produce effective crosslinking and polymer tangles filler particles.
