Products Description
Properties of GPPS
(1) GPPS for colorless transparent particles, burning smoke and with turpentine smell, blow out the stretch
filament; The quality is hard like glass, and the sound is similar to metal when falling or beating. It can be broken but not
bent, and the fracture shows clam shell color silver light. The water absorption rate of PS is 0.05%, which is slightly higher
than PE, but it has little influence on the strength and dimensional stability of the product.
(2) Good optical property transparency is the biggest characteristic of PS, transmittability can reach 88%~92%, like PC and PMMA
belong to the most excellent transparent plastic varieties, known as the three transparent plastics in the market.

Properties of GPPS
(3) Mechanical properties PS hard and brittle, no extensibility, tensile near the yield point is broken. PS has the highest
tensile strength and bending among general thermoplastics, and its tensile strength can reach 60MPa. But the impact strength is
very small, difficult to be used as engineering plastics. PS has poor wear resistance and general creep resistance. The mechanical
properties of PS are greatly affected by temperature.
(4) Thermal performance PS heat resistance is not good, thermal deformation temperature is only 70~90℃, can only be used in the
temperature range of 60~80℃ for a long time. The low temperature resistance of PS is not good, and the embrittlement temperature
is -30℃.

Properties of GPPS
(5) Electrical performance PS has excellent electrical insulation, and is not affected by temperature and humidity, dielectric
loss Angle tangent value is small, can withstand appropriate corona discharge, good arc resistance, suitable for high frequency
insulation material.
(6) Chemical resistance PS chemical stability is good, can resist general acid, alkali, salt, mineral oil and low alcohols, but
can be eroded by many hydrocarbons, ketones and advanced fatty acids, soluble in aromatics. PS weather resistance is not good, its
light resistance, oxidation are poor, not suitable for long-term outdoor use; But PS has good radiation resistance.
