GRG (Glass Fibre Reinforced Gypsum)

plastec GRG (Glass Fibre Reinforced Gypsum) consists of high grade Alpha gypsum, glass-fibres strand and approved silicon additive for moisture resistance properties. Its does not contain any asbestos or other inorganic fibres. GRG has high impact strength and allow fabrication of strong, durable and resilient gypsum product, its fire resistant comply the building authority fire code. Hence with superb fabrication flexibility and fast installation, it is ideal for variety of architectural applications

PRODUCT PROPERTIES FIRE RESISTANCE GRG Product is non-combustible which comply with the building authority fire code. Tested in accordance with BS 476 Part 4 : 1970. MOISTURE RESISTANCE With a moisture resistance properties by adding silicon additive during fabrication process (Hydrophobing treatment - a process to make powder casted material water repellant and free flowing) Passed the requirement under water absorption test BS 1230 Part 1 : 1985 THERMAL & SOUND INSULATION Tested to ASTM C518 : 1991 with result showing excellent thermal conductivity of 0.0918 w/mºk that enhances the cooling and heating effects. The product also experience very low movement in relation to temperature change with Coefficient of Thermal expansion of 6.2x10 -6 tested under ASTM E831 : 1993 Its ability to mould to any design make is a good material for sound insulation and reflection CHEMICAL RESISTANCE plastec GRG product is resistant to dilute chemicals, acids, alkalis, bleaching agents, chlorine solutions and solvents. Hence alkali resisting primers are not requires, Its does not contain any asbestos or other inorganic fibres. FLEXIBILITY plastec GRG allows fabrication flexibility to various design patterns, shapes and sizes to architectural applications. Offer an extensive choice of perforations in square or round to various percentages. IMPACT RESISTANCE plastec GRG fabricated from High grade Alpha gypsum material that has low water demand, with density of 1650kg/m³, resulting in high strength and durability Test results show a Compressive Strength of 23.7 N/mm², Flexural Strength of 30.9 Mpa and Impact Strength of 45.4 KJ/m²   TECHNICAL DATA plastec GRG (Glass-Fibre Re-inforced Gypsum) consists of high grade Alpha gypsum and glass-fibre of 5% to 6% by weight, white in colour with smooth surface and lightly textured at reverse, with density of 1,660kg/m³ and non-combustible SPECIFICATION AND PROPERTIES Test Standards PSB Density Normal Dry Density 1,660kg/m³   Size Thickness Min 5mm   Strength Compressive Strength Tensile Strength Flexural Strength Modules of Elasticity, Tangent Charpy Impact Strength Rockwell Hardness 23.7 N/mm² 14.2 KN 28.8 N/mm² 7522.1 Mpa 45.4 KJ/m² M52 ASTM C109 ASTM D 1037 : 1999 ASTM C580 - 98 ASTM C580 - 98 ASTM D6110 : 1997 M' Scale Value Water Absorption (at 20 ± 2ºC for 2 hr) 0.30% BS 1230 : Part 1 : 1985 (Max 5%) Thermal Insulation Thermal Conductivity Coefficient if Thermal Expansion 0.0918 w/mºk 6.2x10 -6 inch/inchºF ASTM C518 : 1991 ASTM E 831 : 1993 Fire Performance   Non-combustible BS 476 Part 4 : 1970
