Styrolution® PS 2710 is a high-performance, amorphous thermoplastic polymer designed to meet the rigorous demands of the appliance industry. Its unique two-phase microstructure, consisting of a rigid polystyrene matrix with dispersed polybutadiene rubber particles, provides an exceptional balance of stiffness, processability, and impact strength.
The core value of PS 2710 lies in its formulation to resist chemical and mechanical attack, ensuring the integrity and longevity of your products, especially in challenging environments like refrigerator liners exposed to polyurethane blowing agents and food oils.
