Complaint
The strong polarity of side -CN group is introduced into the molecular chain of AS plastic particle-styrene acrylic copolymer, so that the copolymer has the following changes in the properties of polystyrene copolymer: (1) With good oil resistance and hydrocarbon solvent resistance, but also improve the alcohol resistance and resistance to most chlorinated hydrocarbons acid and alkali resistance detergent, stain removers and other solvents, chemical reagents, but ketones, some aromatics and some chlorinated hydrocarbons can still make it dissolve, (2) softening point, improve, The heat resistance is improved, the softening point of Vica is about 25 ~40°C higher than that of polyphenylene, the continuous use temperature is between 75 ~ 90°C, and the thermal deformation temperature is 82 ~ 105*C(1.81 MPa). (3) The toughness is improved, and the material is endowed with stress cracking resistance, crack expansion resistance, and seismic resistance. (4) The rigidity increases, the mechanical properties improve, the shrinkage rate of molding and its fluctuation range decreases, which is conducive to the plastic parts with higher molding accuracy. (5) the liquidity has been reduced, and the processability has become slightly worse. (6) hygroscopicity increases. (7) The thermal stability is slightly lower than that of polystyrene. (8) electrical properties become less than polystyrene, such as dielectric constant about 2.8~3.3, volume resistivity is not less than large, dielectric loss factor (7 ~ 12), are slightly second son polystyrene.
