13 020 000 Silicone Rubber Compound A4099 for Mould Making – 300 × 300 × 6 mm

The Silicone Rubber Compound A4099 is a professional-grade material developed for the production of precision moulds in jewellery casting and model making. Designed for reliable and accurate mould production, it provides excellent performance in demanding workshop and foundry environments.

The material vulcanizes at 90 °C and features a medium hardness of 44–46 Shore A, offering the ideal balance between flexibility and structural stability. This ensures precise mould integrity while allowing easy removal of delicate wax or model parts.

Thanks to its uniform material structure, the silicone rubber delivers outstanding detail reproduction and smooth surface quality. This makes it particularly suitable for jewellery casting, goldsmith workshops, and precision mould-making applications.

Supplied as a sheet measuring 300 × 300 × 6 mm, it is perfectly suited for standard vulcanizing frames and professional mould production systems.
