When this kind precipitated silica is used in silicone rubber compounders by providing:
More flexible inventory management through reduced shelf hardening;Faster, more efficient mixing and re-milling of elastomers;less fly-loss-related product waste
silicone rubber applications have certain physical strength requirements for example: wire and cable, medical and surgical, belting, hose, tubing and various fuel-resistant rubbers uses.
When physical strength is a primary concern, reinforcing silica is the filler of choice.
Precipitated Silica is used in Silicon Rubber for following reasons :
• Improves process ability of raw mixture.
• Offers resistance to heat aging.
• Minimizes crape hardening.
• Provides superior resilience and compression set.
