Technical data: Fibre type: E-Glass. Shape in section: Round. Fibre coarseness: 9–14 µm. Length: 3 mm ± 5 mm. Specific gravity: 2.53–2.55 g/cm³. Resistance to dry heat: ca. 315 °C. Softening temperature: approx. 840 °C. Moisture content on delivery: max. 0.3 %. Colour: White. Surface treatment: Silane based 0.5–1.5 %. Resistance to light, to weather, to ageing = good. Acid resistance = good. Alkali resistance = limited. Solvent resistance = good. Swelling value in water = 0 %. Applications: Fibre pastes and moulding compounds, synthetic plasters, putties, adheslves, corrosion protection coats, asbestos substitutes. In the case of coupling layers to fill and back up edges and embed alignment dowels and screw unions in mould construction, a mixture of 50 % vol. chopped glass fibre and 50 % vol. cotton flock is mostly used. The volume details are intended to assist in judging the amount supplied. These details refer to the loose bulk amount. The contents may become compressed during transport or storage.
