Resin monomer ADC
The company brand JK-50 is a thermosetting resin monomer, also known as Columbia resin, ADC (PPG registered the product as CR-39), which is widely used in the manufacture of resin lenses or other plates. The finished product has a refractive index of 1.498, an Abbe number of 58, and a specific gravity of about 1.32g/cm3, and its weight is about half of ordinary glass products. The finished product made of allyl diethylene glycol carbonate also has strong impact resistance and anti-sag performance. It can rebound high-speed particles and is not easy to damage the surface. Even if it is broken, the cutting edge of the fragments is blunt; because of its low thermal conductivity , So it has better anti-fog performance. The process of manufacturing the finished product is simple, and the surface of the finished product can be hardened and dyed. The application is more and more extensive. Technical indicators of diallyl diethylene glycol carbonate: English name: Dially1 2, 2, -oxydiethyl dicarbonate Appearance: colorless to slightly yellow viscous liquid Molecular formula: C12H18 O7 Molecular weight: 247.27 CAS NO.: 142-22-3 Project indicators Density (20℃)/(g/ml) 1.10～1.20 Viscosity (25℃)/(mPa·s) 10～20 Refractive index (20℃) 1.450～1.460 Moisture/% ≤0.1 Melting point/℃ 0～4 Color (Pt-Co) (25℃) ≤30 Packing: 220kg/drum
