GPPS
GPPS is colorless, odorless, tasteless, shiny, transparent, beaded, or granular solid. Density 1.04 ~ 1.09, transparency 88% ~ 92%, refractive index 1.59 ~ 1.60. Under stress, birefringence is produced, which is called stress-optical effect. Products of the melting temperature of 150 ~ 180 ℃, thermal decomposition temperature of 300 ℃, thermal deformation temperature of 70 ~ 100 ℃, the long-term use of temperature is 60 ~ 80 ℃.
