描述
ULTEM Resin CRS5211R is a 20% glass fiber reinforced, enhanced flow polyetherimide (PEI) copolymer manufactured by SABIC. As an authorized distributor and trader, we supply genuine SABIC materials with full traceability.
This grade is specifically engineered for applications requiring superior chemical resistance to strong acids, bases, aromatics, and ketones combined with the enhanced stiffness provided by 20% glass fiber reinforcement. It features enhanced flow for easier processing of complex parts and internal mold release for improved demolding efficiency. It is a PFAS-free, amorphous, flame retardant PEI copolymer ideal for harsh chemical environments where standard engineering plastics may degrade. [0†L8-L10][1†L5-L7]
ULTEM CRS5211R offers an excellent balance of chemical resistance, mechanical strength, and processability. The 20% glass fiber reinforcement provides significantly higher stiffness and dimensional stability compared to unreinforced grades, while the enhanced flow characteristics enable easier processing of complex parts.
