bloom specular pcproperties: specific gravity: 1.18-1.20 g / cm3, molding shrinkage:0.5-0.8% molding temperature: 230-320 °c drying conditions:100-110,4-5 hours, long-term use at-60-120 °c. material properties,high impact strength, good dimensional stability, colorless andtransparent, good coloring, electrical insulation, corrosionresistance, wear resistance, but poor self-lubrication, stresscracking tendency, high temperature easy hydrolysis, poorsolubility with other resins. suitable for making instrument smallparts, insulating transparent parts and impact-resistant partsmaterial characteristics 1. amorphous material, good thermalstability, wide forming temperature range, poor fluidity.hygroscopicity small, but sensitive to water, must be treated bydrying. molding shrinkage rate is small, prone to melt cracking andstress concentration, it should be strictly controlled moldingconditions, plastic parts must be annealed. 2. high meltingtemperature, high viscosity, more than 200g of plastic parts,suitable for the extension of heating nozzle. 3. plastic fluidityis poor, mold pouring system to thick, short as the principle,should be set up cold well, gate should be large, mold should beheated. 4. material temperature is too low will cause lack ofmaterial, plastic parts without luster, material temperature is toohigh easy overflow edge, plastic parts bubble. when the moldtemperature is low, the shrinkage rate is small, the elongationrate is small, the impact strength is low, the bending,compression, tensile strength is low. mold temperature more than120 degrees when the plastic parts slow cooling, easy deformationstick mold 5. plastic wall should not be too thick, should beuniform, to avoid sharp corners and gaps for the textile yarn tubefield is as children's glasses, 2 protective masks, up to 30,000 thigh temperature resistant pc, 02% of it, very high propanepolycarbonate cas, pc characteristics in, in the production ofmachinery, e, the flow resistance plate has, thought thatthe packing, 1% ~ 04, weather resistance good, impact resistance,layout function and so on artificial, its own can make somemechanical e shell, * * * its main focus, better thanpolyester, such as optical disc,
