Polystyrene resin is a non-toxic, odorless, and colorless transparent material composed of glass-like brittle particles. Its products exhibit extremely high transparency, with a light transmittance of up to 90%. Additionally, it possesses good electrical insulation performance, is easily colored, and has excellent processing fluidity. Furthermore, it demonstrates good rigidity and chemical corrosion resistance. However, ordinary polystyrene has several shortcomings, including brittleness, low impact strength, susceptibility to stress cracking, poor heat resistance, and no resistance to boiling water. |
