Detailed Description

China manufacturer mold making liquid silicone rubber for Grc Gfrc moulding

Grc & Gfrc Molding Silicone

1. Description

GRC/GFRC is a new kind of material used today for home decor items as well as ornamental moldings.

GC Silicone manufactures two-component, room temperature curing silicone mold materials that are used widely in the grc/gfrc casting industry to create highly detailed decorative parts.

GRC/GFRC can be cast repeatedly into silicone molds without release agents. The primary differences between polyurethanes and silicones are the cost (silicones are more expensive than polyurethane) and the range of hardness available within the product lines. For highly detailed and delicate castings, silicone rubbers may be necessary as they are available in softer and more flexible options compared to polyurethanes.

The popular silicone mold rubber is C-825/C-830 for these applications. A tin-cured silicone rubber with a 100A:3B mix ratio; measure with a digital scale.

We manufacture and supply figurines molding silicone rubber, sculpture molding silicone rubber, foundry molding silicone rubber, art casting silicone rubber, foundry casting silicone rubber, etc with best quality and price in China.

Note: The choosing of suitable hardness should be according to the size and pattern design of the products. If large products and therefore multiple-piece molds are needed by customers, silicone rubber with higher hardness will be required for the molds. Conversely, soft silicon is indispensable for molds with complicated pattern and delicate details. The amount of curing agent admixture depends on the actual need of customers. More will be added for speedy drying and fast release and less when otherwise.
