SR-520 Hydrophobic Precipitated Silica

SR-520 Hydrophobic Precipitated Silica

Features:

SR-520 Hydrophobic Precipitated Silica is derived from silica gel-grade precipitated hydrated silica with a specific surface area of 130-170 m²/g, treated with high-hydroxy silicone oil. The treatment method involves surface coating and in-situ modification.

Applications:

  • High-temperature silicone rubber (HTV)
  • Rollers and other silicone elastomers
  • Rubber and plastic materials

Properties:

  • In HTV, it increases the additive ratio to meet the special requirements of silicone products.
  • Enhances elasticity in silicone elastomers.
  • Suitable for formulations requiring a high filler loading.
