GPPS is a shiny, transparent particle. Light, cheap, low water absorption, good coloring, dimensional stability, good electrical properties, transparent products, easy processing. GPPS is soluble in aromatic hydrocarbons, chlorinated hydrocarbons, aliphatic ketones and esters. It is resistant to some mineral oils, organic acids, bases, salts, low-level alcohols and their aqueous solutions. Low water absorption, can still maintain its mechanical properties and dimensional stability in wet environment. Excellent electrical performance, high volume resistance and surface resistance, and not affected by temperature, humidity changes, also not affected by corona discharge. Radiation resistance is also very good. The main disadvantages of GPPS are brittle and easy to crack, low impact strength, poor heat resistance, can not withstand boiling water, can only be used at lower temperature and lower load. Poor sunlight resistance, flammable. When burning black, and a special odor.
Nature
General grade polystyrene is a thermoplastic resin, colorless, odorless, tasteless and shiny, transparent beads or granular solid. Density 1.04~1.09, transparency 88%~92%, refractive index 1.59~1.60. Under the action of stress, birefringence occurs, which is called stress-optical effect. The melting temperature of the product is 150~180ºC, the thermal decomposition temperature is 300ºC, the thermal deformation temperature is 70~100ºC, and the long-term use temperature is 60~80ºC. At 5~6ºC lower than the thermal deformation temperature, the stress can be eliminated and the thermal deformation temperature can be increased after annealing treatment. If a little α -methyl styrene is added in the production process, the heat resistance grade of universal polystyrene can be improved. It is soluble in aromatic hydrocarbons, chlorinated hydrocarbons, aliphatic ketones and esters. It is resistant to some mineral oils, organic acids, bases, salts, low-level alcohols and their aqueous solutions. Low water absorption, can still maintain its mechanical properties and dimensional stability in wet environment. Second only to acrylic resin in optical properties. Excellent electrical performance, high volume resistivity and surface resistivity, and not affected by temperature, humidity changes, also not affected by corona discharge. Irradiation resistance is also very good. Its main shortcoming is qualitative brittle crack easily, impact intensity is inferior, heat-resistant sex is poorer, cannot withstand boiling water, can be used only below lower temperature and lower load. Poor sunlight resistance, flammable. When burning, black smoke, and a special smell.
Application
General level of polystyrene and can be used for daily necessities, electrical, instrument shell, toys, lamps and lanterns, household appliances, stationery, cosmetic containers, the room inside and outside decoration, fruit tray, optical components, such as prism, lens, lens window glass and molding, headlights, telecom accessories, electrical frequency capacitor films, containers, such as high-frequency insulation materials, TV guide, chemical containers, etc. Suspended polymer resin can be made into foam plastic of different density, used for heat insulation, sound insulation, shockproof, floating, packaging materials, cork substitutes, pre-foaming foam body can be used as water filtering medium and preparation of light concrete, low foaming plastic can be made into synthetic wood furniture, etc. High impact polystyrene(HIPS) can be molded or extruded into various products, suitable for shell of household appliances. Electrical appliances, instrumentation accessories, refrigerator lining, plate, TV, radio, telephone shell, cultural and educational supplies, toys, packaging containers, daily necessities, furniture, tableware, tray, tableware, structural foam products, etc. There are some questions you may would like to know: Q1.
