In
an era where electronics manufacturing pursues extreme efficiency, the
curing speed of encapsulation materials often dictates the rhythm of the
production line. Traditional heat-vulcanized fluorosilicone rubber,
while offering superior performance, suffers from long vulcanization
times and high energy consumption, making it ill-suited for the mass
production of miniature components. Recently, the advent of a new
"Liquid Fluorosilicone Rubber (LSR)" technology has broken this
bottleneck, reducing curing time to mere seconds and bringing a
revolutionary change to precision electronics encapsulation.
According
to the R&D team, this new liquid fluorosilicone rubber employs an
advanced platinum-catalyzed addition reaction system. Unlike traditional
peroxide vulcanization, this system triggers an instantaneous
cross-linking reaction under heat, achieving extremely high physical
properties without the need for secondary vulcanization. Experimental
data shows that the material can be fully cured and demolded in just 30
seconds in a 170°C mold, increasing production efficiency by more than 5
times.
Even
more remarkable is its exceptional fluidity. With extremely low
viscosity, the material can penetrate micron-level gaps like water. This
means it can perfectly fill complex structures such as chip pins and
sensor micro-pores without generating air bubbles or voids. In terms of
chemical resistance, it inherits the excellent genes of fluorosilicone
materials, showing outstanding resistance to gasoline, aviation
kerosene, strong acids, and alkalis, while maintaining elasticity across
a wide temperature range of -60°C to 230°C.
Currently,
this technology has been successfully applied to the encapsulation of
automotive pressure sensors, miniature microphones, and high-frequency
connectors. Industry analysts believe that the widespread adoption of
liquid fluorosilicone rubber marks a new era for electronics
encapsulation materials, where "high performance" and "high efficiency"
are equally prioritized.
