BASF has added "a new component" to a classic Ultrason E formulation which it says contributes to increased stiffness at elevated temperatures while simultaneously improving the flow characteristics of the PESU melt significantly and without noticeably compromising the dimensional stability
of the material.
Its high strength and dimensional stability
are critical in producing the test sockets used for today's very small devices.
H&V's new ViaMat nonwoven aramid paper features extreme surface smoothness for uniform resin application and low CTE (Coefficient of Thermal Expansion) for excellent dimensional stability
as aramid fibers exhibit a negative CTE and restrain expansion of applied resins.
Says GE Plastics, Extem resins meet demand for easy-to-produce parts that can maintain stiffness and dimensional stability
at higher temperatures in harsh chemical environments.
The Dimensional Stability
of Cast 319 Aluminum," James M.
Lab tests and paper machine results show that BCTMP can achieve better dimensional stability
Alextra sheet products have unrivalled depth of image, robust weathering, high regrind compatibility, excellent toughness, dimensional stability
, and are easily thermoformed.
Stanyl TE250F6 was selected because of its flow properties, elevated temperature resistance, improved heat dissipation, and dimensional stability
Long-term dimensional stability
and foam adhesion to facers were not thoroughly evaluated.
They offer high dimensional stability
via low water absorption and high green strength, plus faster processing speeds and higher accuracy and heat deflection temperatures (HDT of 70[degrees]C with UV-only post treatment and > 100[degrees]C with thermal post treatment).
For extruded goods, SP is said to create faster throughput, low die swell, smooth surfaces and increased dimensional stability
The casting process includes a mechanically induced rapid chilling of the bulkheads to promote swift directional solidification of the aluminum and a fine grain structure, both of which improve dimensional stability
