High Strength, two-component poly-condensation silicone rubber: Globalsil AL
Two-component room temperature vulcanising pourable silicone rubbers which cure with the addition of the appropriate hardener according to poly-condensation process. GLOBALSIL AL are suited for the manufacturing of moulds and forms for the casting of plaster, wax, concrete, polyester, epoxy and polyurethane resins, and other materials. These rubbers are highly anti-adherent flexible compounds extremely suitable for the re production of fine details and for easy removal of complex replica parts. They have very good mechanical properties, and a very low linear shrinkage. Highly used for re production of objects rich in details and undercuts.

Low Strength, two-component poly-condensation silicone rubber: Globalsil BL
Two components room temperature vulcanising pourable silicone rubbers which cure on the addition of the appropriate hardener according to the poly condensation process. These rubbers are highly anti-adherent flexible compounds extremely suitable for the re production of fine details and for easy removal of complex replica parts, they are characterized by a low viscosity and an easy degassing process. Particularly suited for the production of plaster moulds and aluminum moulds in the footwear industry, they are also used for technical objects like rosettes, frames, and for all those applications where a high Tear strength is not required.

Fluid, two-component room temperature vulcanising pourable silicone rubbers which cure on the addition of the appropriate hardener according to the poly condensation process. GLOBALSIL HTR has a high hardness shore and a great thermal resistance (up to about 300°C). The product is well suited for flexible moulds for the reproduction of small objects in tin, lead, and low melting alloys.
