Physical properties of polycarbonate
Chemical name: polycarbonate Name: polycarbonate, commonly known as PC bulletproof glue
Thermal deformation temperature: 132 ℃ - 142 ℃
Tensile strength: 57.2mpa, elongation at break: 26%
Yield bending strength: 86.6mpa, notched impact strength of simply supported beam: 45khg / (CM) 2
Thermal degradation rate: > 7 ∽ < 12 dielectric coefficient: 16
Volume resistance coefficient: 1.5 × 1015 Ω. Cm, performance in accordance with Hg / T 2503-93 standard
Material properties:
High impact strength, good dimensional stability, colorless and transparent, good coloring, good electrical insulation, corrosion resistance, good wear resistance, but poor self-lubricating, poor stress cracking tendency, poor solubility with other resins.
Advantages and features
Fire resistance: the natural temperature of polycarbonate is 630 ℃. According to the test by the national fire protection building materials quality supervision and testing center, the fire resistance rating of PC board reaches GB (8624-1997) B1, which belongs to fire-resistant engineering materials.
Chemical resistance: polycarbonate has good chemical resistance, and can withstand the corrosion of various organic acids, inorganic acids, weak acids, vegetables, neutral salt solutions, aliphatic hydrocarbons and alcohol at room temperature.
Heat and cold resistance: with good temperature resistance, it can adapt to all kinds of severe weather changes from severe cold to high temperature, and all physical performance indexes are stable within the range of - 30 ℃ to 120 ℃.
Photochemistry: polycarbonate has a light transmittance of * * in the visible and near-infrared spectral areas, with a light transmittance of 12% - 18%. It is UV resistant and anti-aging.
Product surface contains UV resistant coextrusion layer, good outdoor weather resistance, long-term use can maintain good optical and mechanical properties.
Impact resistance: the impact strength is 80 times that of glass, and the solid plate is 200 times that of glass. Prevent damage during transportation, installation and use.
In addition, its biggest feature is that it will not be broken like ordinary glass, avoiding direct damage to man-made products, and greatly ensuring the safety.
Light weight: the same glass with a weight of 1 / 12-1 / 15 is safe and not broken, easy to handle and install, reduces the self weight of the building, and simplifies the construction. This product is suitable for beautifying public buildings, civil buildings and industrial buildings.
