“Noryl” polyols and “Superflow Ultem” resins for BiTS

Saudi Arabian petrochemicals group Sabic (Riyadh; www.sabic.com) is introducing “Superflow Ultem SF2250EPR” and “SF2270” within its portfolio of “Superflow Ultem” resins. The two new grades feature unique flow properties for moulding burn-in test sockets (BiTS) used to stress-test integrated circuit (IC) chips.
They can also potentially be used to mould thin-wall, high-precision, miniaturised connectors, and can be used as alternatives for incumbent materials such as glass fibre-reinforced liquid crystal polymers (LCPs) and polyethersulfone (PES) resins. They deliver greater weld line strength and mechanical performance than LCPs, and higher tensile strength and modulus, higher weld line strength and lower moisture absorption than PES resins, claims Sabic.

The company also recently launched “Noryl AP2001G” aromatic polyol, which it says can improve the performance of hot cast polyurethanes based on methylene diphenyl diisocyanate (MDI) and polytetramethylene ether glycol (PTMG).
By boosting the hardness, toughness and stiffness properties of cast PU by double digits, the new polyol can enable MDI formulations cured with 1,4-butanediol (BDO) to deliver equivalent or better performance compared to toluene diisocyanate (TDI) and PTMG PU formulations cured with MOCA (4,4-methylene bis(ortho-chloroaniline)).
