Silbione · Elkem Silicones ·

Two-component, addition-curing SILBIONE-RTV paste for footcare applications, curing at room temperature in a 1:1 ratio. Hardness according to the Elkem data sheet approx. Shore A 20.

SILBIONE RTV 4320 A and B are pasty, addition-curing silicone components, mixed by hand in 100 parts each (1:1 ratio). After a total processing time of approximately 2 minutes at 23°C and a setting time of approximately 4 minutes, an elastomer with a Shore A hardness of approximately 20 is formed. According to the Elkem data sheet, it is suitable for the production of orthopedic insoles and heel spur braces.

Regulatory notice

According to the Elkem data sheet, extensive toxicological tests on SILBIONE products have demonstrated sufficient biocompatibility and suitability for the recommended applications. SILBIONE RTV 4320 A and B meet regulatory requirements in several countries and comply with a number of medical and pharmaceutical regulations, according to the Elkem data sheet. Furthermore, the Elkem data sheet states that no toxic substances are released before or after polymerization. We can assist you with selection and approval for medical or skin contact applications.
