Cork (granulated 4-6mm)

Granulated Cork – 4–6 mm
Material: Natural Cork (Quercus suber)
Grain Size: 4 to 6 mm
Appearance: Light brown, irregular granules
Density: ~100–200 kg/m³ (variable)

Description:
Granulated cork is a lightweight, renewable material made from the bark of the cork oak tree. This 4–6 mm fraction offers a coarse grain size, ideal for insulation, lightweight fillers, gaskets, pyrotechnics, and craft applications. It is chemically inert, elastic, compressible, and resistant to moisture, mildew, and many chemicals.

Applications:

Construction & Insulation

• Used as thermal and acoustic insulation in walls, floors, and roofs

• Fills expansion joints in concrete and other building materials

• Lightweight aggregate in plasters or mortars

Pyrotechnics

• Acts as a shock absorber and spacer in rocket motors and mines

• Used in lift charges and burst delays for fragmentation buffering

• Creates low-density effects or debris-like particles in special compositions

Crafts & Model Making

• Ideal for terrains, dioramas, basing material (simulates bark, rocks, or dirt)

• Can be colored or painted for visual effects in miniatures or scenery

Industrial

• Added to rubber/plastic blends for producing gaskets, floor tiles, and vibration-dampening parts

Key Properties:

• Natural & biodegradable

• Excellent elasticity and recovery

• Chemically stable and low conductivity

• Low water absorption

Handling & Storage:
Store in a dry, well-ventilated area. Avoid prolonged exposure to moisture. Safe to handle with minimal PPE.

Packaging:
Available in 250 g, 500 g, 1000 g bags or bulk sacks upon request.
