Regulatory & Compliance

Certifications & Compliance: FDA 21 CFR Regulations
Food Legislation: If used unmodified and under appropriated processing conditions, Polystyrene HI-800 (H.G) 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 HI-800 (H.G), 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.
