Standard Silicone Sponge Density:

The standard sponges are: White, Black (Dark Grey) and Red Iron Oxide. There are 4 standard densities off the shelf: Of these, the Sil16 (250KG/m3) is the most available and common grade.

Code: SIL10 = 10 lb/ft3 (200Kg/m3) (SE510)
Code: SIL16 = 16 lb/ft3 (250Kg/m3) (SE515)
Code: SIL24 = 24 lb/ft3 (400Kg/m3) (SE524)
Code: SIL33 = 33 lb/ft3 (500Kg/m3) (SE533)

Standard Sponge Thicknesses:

(Based on Sil16. Please esquire for stock availability if you require a different density)
