Filling of Silica powder with Epoxy resin and Hardener with Accelerator

SILICA POWDER SAND FOR EPOXY RESIN

The granulometric data and physical characteristics of silica powder used with epoxy resin for transformers can vary depending on the specific requirements of the application. However, here are some general data and characteristics that may be relevant:

Granulometric Data: Silica powder used with epoxy resin for transformers typically has a particle size distribution ranging from 5 to 50 microns. The distribution of particle sizes is important because it can affect the viscosity and flow properties of the epoxy mixture, as well as the mechanical properties of the cured material.

Physical Characteristics: Silica powder is a fine, white powder that is odorless and insoluble in water. It has a high melting point (around 1,710°C or 3,110°F) and is chemically inert, meaning that it does not react with other materials. Silica powder is also non-toxic and has low electrical conductivity.

Density: The density of silica powder can vary depending on the specific grade and particle size. Generally, it ranges from 2.2 to 2.7 g/cm3.

Thermal Conductivity: Silica powder has a low thermal conductivity, which means that it does not conduct heat well. This can be useful in transformer applications, where it is important to minimize heat transfer between different components.

Moisture Content: Silica powder can absorb moisture from the air, which can affect its properties and performance. Therefore, it is important to store and handle silica powder in a dry environment.

Overall, the granulometric data and physical characteristics of silica powder used with epoxy resin for transformers can play an important role in determining the performance and properties of the final product. It is important to choose the right type and grade of silica powder to ensure that it meets the specific requirements of the application.

Features:

Crystalline silica is produced from a high purify quartz feed stock for manufacturing and 

formulation of applications which require structurally sound, chemically pure or non-reactive fine mineral fillers.

Completely inert and pH neutral, we will not alter or initiate when incorporated in

Catalyzed or multi-component chemical systems, and will not degrade when employed

In extreme temperatures or harsh environments. We offers formulators a low surface

Area, minimal oil absorption to achieve high loading in coatings and cementitious systems

And stiffening in elastomeric and high performance epoxy. Chemically pure we also serves an

Excellent nonconductor in electrical assemblies and potting compounds, and a non-combustible

Filler in thermal insulating.

The grade is processed with adherence to ISO and internal quality assurance programs.

The result is chemical purity and consistently uniform particle size distributions for predictable results supported by reliable services.
