Basic Info.
Product Description
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.
In the mechanical and electrical industry, instrumentation, communication equipment industry and other aspects has been widely used in a variety of instrument shell, lamp cover, optical parts, instrument parts, transparent window mirror, transparent model, chemical acid storage tank, acid conveying tank, telecommunications parts, high frequency capacitor, high frequency insulation pad, bracket, insert and frozen insulation materials.
Also widely used in a variety of daily necessities, such as bottle caps, containers, decorations, buttons, combs, toothbrushes, soap boxes, cigarette boxes and toys, etc.
