Precipitated Silica: Uses and Production Process

Image
  Precipitated silica is a form of synthetic and amorphous silica and it is derived from the quartz-sand that is the crystal form of the silicon dioxide. The physical properties can be manipulated rather easily while it is in the process of manufacturing in order to further deliver products that has plethora of features that’s needed to enhance its features, that are engineered specifically for various end-usage applications, like the Silica from Rice Husk Ash . The precipitated silica is used in several industries which include: Industrial rubber – Precipitated Silica for Rubber Precipitated silica for tires Silicone rubber Footwear Agricultural products Coatings, paints and inks Adhesives and sealants Footwear Here’s a small brief of the whole process constituting how precipitated silica is prepared: Precipitation. First of all, the sodium silicate solution and mineral acid is allowed to properly react with each other in an agitated vessel to further produce a slurr

Advantages of Precipitated Silica for Rubber Applications!

Image
Available in a wide-variety of formulations, the purity, quality and the proven performance of precipitated silica products produced by the Precipitated Silica Suppliers enables it to function as value-focused and premium alternatives to the fumed silica in non-black, black, translucent and colored rubber compounds by incorporating following mechanical properties: Cost-effective reinforcing strength   Excellent tensile strength, flex-fatigue resistance, and tear strength Reduced compression set resistance Exceptional resistance to heat aging Outstanding compression set resistance These properties, together, have potential to minimize the process inefficiencies and costs of silica rubber compounders and Precipitated Silica for Tyres by providing: Faster, more-efficient re-milling and mixing elastomers Less fly-loss-related product waste More flexible management of inventory through less shelf hardening The precipitated silica suppliers offer a complete selection of the speci

Applications of Precipitated Silica

Image
Adhesive Precipitated silica is highly useful in enhancing strength of the bond and as a thickening and reinforcing agent. The highly dispersed silica particles contained within liquid adhesive will harden fast when it’s in contact with any solid surface. In synthetic and natural rubber-based adhesives both. Silica provides reinforcement, promotes adhesion, and thixotropy, and also serves as extenders which raises the quality of the product and also lowers cost. To provide reinforcement and adjust rheology. Silica will prevent resin separation and settling of the heavy fillers and pigments. It also prevents excessive penetration of the adhesive into the porous adherents. Silica will improve flow control and also heat resistance of hot-melts in application. Silica also serves as a free-flowing agent for spray-dried resins. Footwear Dispersed silica is used a lot in shoe soles pertaining to its resistance to wear and tear, its non-scuffing characteristics to obtain compounds with

What is Precipitated Silica?

  A form of synthetic, precipitated amorphous silica, precipitated silica is derived from quartz-sand which is a crystal form of silicon dioxide. Physical properties of this precipitated silica could be easily manipulated during the process of manufacturing it in order to deliver the products with wide range of features need to enhance the features, which are engineered for lots of different end-usage applications, such as precipitated silica for rubber .                                              Precipitated silica is used in many industries including: ·  Precipitated silica for tyres ·  Industrial rubber ·  Food ·  Silicone rubber ·  Footwear ·  Agricultural products ·  Battery separator ·  Adhesives and sealants ·  Coatings, inks, and paints Here is the brief of the process of how precipitated silica is manufactured: 1.  Precipitation. First mineral acid and sodium silicate solution are allowed to react in agitated vessel in order to produce slurry of the amorphous silica particl
