HIGH PERFORMANCE AUTOMOTIVE SENSORS
SABIC’s ULTEM™ 2300 & ULTEM 2310 resins offer a balance of properties to address demanding material requirements of automotive sensors. They can be used for sensors that need to perform under harsh conditions involving moisture, a broad range of temperatures and automotive fluids.
MOISTURE AND HIGH HEAT RESISTANCE
ULTEM™ 2300 & 2310 resins are differentiated from other mainstream thermoplastics due to their excellent strength and dimensional stability when exposed to a combination of moisture and high temperatures. Sensors made from competitive materials may fail prematurely when exposed to these harsh conditions.
Thermoplastics, such as polyethersulfone (PES and
polyamide (PA66), have a higher moisture intake than
ULTEM resin. Polyphenylenesulfide (PPS) and PA66 are
less suitable for sensor applications when dimensional
stability becomes a critical issue at temperatures
exceeding 100°C.
ULTEM 2300 resin is a standard flow 30% glass fiber
reinforced polyetherimide (PEI) resin. For even better
flow to produce smaller and thinner-wall components,
ULTEM 2310 resin offers improved melt flow.
To avoid a breakdown of signals because of a mismatch
in thermal expansion, metal to metal connectors may
still be preferred. ULTEM 2300 & 2310 resins, with a
coefficient of thermal expansion close to metal, are wellsuited to overmold these connectors.
The excellent dimensional stability of these resins can
also support the potential for full thermoplastic sensor
solutions, which can enable complex designs and
simplification of the assembly through part integration
of the fluid and connector sides
STRENGTH AND CHEMICAL RESISTANCE
ULTEM™ 2300 & 2310 resins provide similar mechanical and chemical performance. Both grades offer excellent dimensional stability, strength, stiffness, chemical resistance, and creep resistance under high temperatures due to their high glass transition temperature of 217°C.
