- Applications
This grade is specifically suited for Extruded Polystyrene (XPS) production application as it comes without any lubricant to give end product a unified cell structure. Moreover, it can also be used for general injection moudling.
Processing:
- Extrusion
- Injection Molding
- Processing
Although Polystyrene GP-525X can be processed by any method applicable to polystyrene based plastic, it is best suitable for injection molding and extrusion molding. The melt temperatures should not exceed 260 °C .

Regulatory & Compliance
- Certifications & Compliance
- Food Legislation
If used unmodified and under appropriated processing conditions, Polystyrene GP-525 conforms with FDA title 21 CFR section 177.1640 regarding the use of in food contact articles. Diamond Polystyrene is also approved by PCSIR (Pakistan Council of Scientific & Industrial Research).
Safety & Health
- Product Safety
During processing of Polystyrene GP-525, small quantity of Styrene Monomer may be released into the atmosphere. At styrene vapor concentrations below 20 ppm, no negative health effects are expected. In our experience, the concentration of styrene does not exceed 1 ppm in good ventilate workplace.
- Environmental
Diamond polystyrene resins can be recycled. Adequate ventilation should be used during processing. Diamond Polystyrene must not be dispose of to landfill or incineration as per government laws and regulations.
