Safety Information

SBS polymers are generally safe but require proper handling to avoid inhalation of processing fumes and skin contact with hot polymer. Use appropriate personal protective equipment including respiratory protection and gloves. Ensure adequate ventilation during processing. Monitor for styrene emissions during high-temperature processing.

Ventilation Required
Generally Safe Polymer
Hot Process Caution

Storage & Handling

Store SBS polymers in cool, dry conditions away from heat sources and UV light. Keep containers sealed to prevent moisture absorption and contamination. Use climate-controlled storage areas. Protect from oxidizing conditions and maintain inert atmosphere when possible.
