ULTEM™ resin CRS5311 (Asia)

ULTEM™ resin CRS5311 (Asia) by SABIC is a flame retardant, PFAS-free, amorphous polyetherimide (PEI) reinforced with 30% glass fiber. It provides good metal adhesion, high strength, high heat resistance and good dimensional stability. It offers low smoke & toxicity, good mechanicals in broad temperature range and low creep sensitivity.

It exhibits low shrinkage, easy flow, high stiffness and hydrolytic stability.
It shows enhanced chemical resistance to strong acids, bases, aromatics, and ketones.
It is suitable for processing by injection molding.
ULTEM™ resin CRS5311 (Asia) is used in automotive (heavy truck, automotive under the hood, aerospace, motorcycle, recreational/specialty vehicle), building & construction (building component), consumer (personal accessory, home & commercial appliance).
It is recommended for electrical & electronics (energy management, drone solutions, mobile phone, computer, tablets, circuit boards/additives, printer copier, speaker and earphone), industrial (material handling), industrial packaging and mass transportation (rail).
It complies with UL 94 V-0 & UL 94 5VA flame rating and ECO regulations.
