描述
ULTEM Resin CRS5201 is a 20% glass fiber reinforced, standard 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 is a PFAS-free, amorphous, flame retardant PEI copolymer ideal for harsh chemical environments where standard engineering plastics may degrade.
ULTEM CRS5201 offers an excellent balance of chemical resistance, mechanical strength, and thermal stability. The 20% glass fiber reinforcement provides significantly higher stiffness and dimensional stability compared to unreinforced grades, while the standard flow characteristics ensure consistent processing of complex parts.
