Expanded Glass Beads - Lightweight beads with good thermal insulation properties
These spherical beads are made from post-consumer recycled glass. The beads are dimensionally stable and highly resistant to moisture, fire, and chemicals. They have a fine closed cellular pore structure, resulting in excellent thermal insulation and sound absorption properties.
Expanded glass beads are used as lightweight filler in dry mortar, tile adhesive, lightweight concrete, acoustic and lightweight boards, and mineral casting. Loose beads are used as a free-flowing thermal insulation material. The beads are added to paints to obtain a sanded texture.
The expanded glass beads are available in sizes from 0.04 mm up to 4 mm. The loose bulk density ranges from 190 kg/m³ to 530 kg/m³ depending on the grade. The two samples have diameters of 2-4 mm and 0.25-0.5 mm.
Mix the beads into biodegradable plastic and mould floats for nets used for commercial fishing.
You get two small vials with two different bead sizes as seen on the product photo.
All samples come with a laminated information card, which includes contact details for the supplier.
