Epoxy Casting Materials

Epoxy casting materials is a product family. It covers multiple grades from pure resin to highly filled compounds. This product family helps buyers select the right grade for different voltage levels, casting sizes, and process conditions. The family is organized by electrical strength from 25 kV/mm to 35 kV/mm in four levels. It is also organized by viscosity from 300 mPa·s to 2000 mPa·s in five levels. Buyers only need to provide voltage level, minimum wall thickness, and curing method. It is available for OEM replacement, aftermarket supply, and bulk orders.

Our epoxy casting materials fit many voltage levels and equipment types. The family is used in dry-type transformer insulation casting at all voltage levels. It also suits high-voltage instrument transformers and insulator molding. Electronic components use it for precision potting and protection. Power capacitors and reactors use it for impregnation. Special electrical equipment uses it for custom insulation solutions. The table below shows typical equipment matching.

These values help buyers compare grades. They also help engineers set process parameters. The data comes from third-party CMA and SGS reports. Each batch is traceable.

This family supports replacement and custom supply. Buyers often come with a device model, drawing, or performance target. They need a material that matches the original insulation system. We review the voltage level, wall thickness, and curing method. Then we recommend the right grade. The table below shows common replacement scenarios.

This family offers several engineering benefits. It covers electrical strength from 25 to 35 kV/mm. It covers glass transition temperature from 120 to 150°C. It covers viscosity from 300 to 2000 mPa·s. It also covers filler content from 0% to 65%. These ranges reduce the need for new formula development. They also improve process matching. Multiple grades share one hardener and one filler system. This reduces storage and changeover cost. The MES system records all production parameters for each batch.

We control quality at every production step. Each batch goes through four inspection stages. These are incoming material check, process check, finished product check, and shipment check. We test electrical strength, viscosity, and heat distortion temperature. We also keep samples for traceability. Our factory holds CMA and SGS reports. These reports verify the key values in the specification table. We provide test data for each shipment.

Buyers can use the table below to match the right grade.

First, confirm the equipment type and voltage level. Second, check the required insulation thickness and curing method. Third, review the viscosity and filler content needs. Fourth, compare electrical strength and heat resistance. Fifth, request a free sample for line testing.
