Import Cheap Liquid Silicone Rubber — Buy in Bulk from Supplier in China

Dongguan Guochuang Organic Silicone Material Co., Ltd. produces a liquid silicone rubber known as C‑825, formulated for lost‑wax casting applications. The material is supplied as a two‑part system: a white liquid base and a non‑toxic, odour‑less transparent catalyst. The base is packaged in drums ranging from 1 kg to 200 kg, while the catalyst is available in 30 g bottles or 1 kg bottles. When stored at or below 32 °C in unopened containers the combined system retains usability for ten months.

The silicone rubber exhibits low viscosity, high flexibility and an extra‑low shrinkage rate, characteristics that align with industry standards for precision casting. Typical Shore A hardness after cure is 30 - 40, tensile strength around 4 - 5 MPa and elongation at break exceeds 400 %. Standard industry guidelines also cite a density of approximately 1.1 g cm⁻³ and a cure time of 30 - 60 minutes at 25 °C, which matches the supplier’s fast, medium and slow catalyst options.

Foundries, sculpture studios and prototype manufacturers commonly use this rubber to reproduce fine details in bronze or aluminium castings. Buyers generally request drums sized to their production volume and may need to confirm the preferred catalyst speed for their seasonal temperature conditions. The supplier does not list a minimum order quantity or payment terms, so importers should verify these details directly before placing an order.
