Enrique Camacho, SIMTEC Silicone Parts, LLC, a solution provider company at the marcus evans Medical Device Manufacturing Summit Spring 2014 and the Medical Device R&D Summit Spring 2014, outlines the benefits and uses of liquid silicone rubber.

1. Interview with: Enrique Camacho,
President, SIMTEC Silicone Parts,
LLC
“With pressure on costing and extended
lifetime performance, medical device
manufacturers need to focus on long-
term costing and price stability for parts
and components currently being
designed,” advises Enrique Camacho of
SIMTEC Silicone Parts, LLC. Although
cost is sometimes a deterrent for
considering Liquid Silicone Rubber
(LSR), it still pays off in the end, he
explains.
SIMTEC Silicone Parts, LLC is an
American solution provider at the
marcus evans Medical Device
Manufacturing Summit Spring 2014
and the Medical Device R&D Summit
Spring 2014, taking place in Las
Vegas, Nevada, June 26-27.
What is challenging medical device
manufacturers today? How could
LSR solve some of those issues?
In medical device manufacturing, the
challenge is in finding an innovative,
cost efficient solution while at the same
time prioritizing safety and functionality.
Medical devices need to perform
perfectly every time; there is no room
for error. Therefore, materials must be
selected very carefully.
LSR is available in medical grades. It is
biocompatible, hypoallergenic, flexible,
durable, and transparent (unless
pigmented); it can be autoclaved, and it
is resistant to ultraviolet rays, stains,
and extreme temperatures. All in all,
LSR provides the level of performance
that medical device applications
demand.
What is LSR often not considered
for, when in fact it would be ideal
for the purpose?
For any new or existing application,
where elastomers or rubbers are being
considered. Any type of seal, gasket,
membrane, coupler, housing, button,
connector, valve, or dampener could
potentially benefit from the superior
temperature resistance, compression
set, chemical resistance, and inertness
that LSR offers.
Cost is always a factor when making a
decision as to which materials to select
for a medical device application, and
occasionally cost is a deterrent in
considering LSR. Medical OEMs
sometimes make the difficult decision to
compromise on part design and
performance in order to save on up-
front tooling costs. LSR is a material
that pays off in the end, not only with
improved part quality but also with the
improved performance of the device.
LSR stands up over time, even with
repeated use. Its material price stability
also allows for costs to be controlled
over the lifetime of the program.
C o u l d t h i s m a t e r i a l g i v e
manufacturers a competitive edge?
It certainly does, especially when the
LSR or LSR 2-Shot (LSR/Thermoplastic)
injection molding process is considered.
The LSR 2- Shot injection molding
process allows for the integration of
multiple materials and functions, and for
the production of complex components
with one injection molding tool in one
injection molding unit. By using this
innovative technology, medical device
manufacturers gain the competitive
edge derived from combining the
attributes of LSR (as mentioned earlier)
and the material properties of a
thermoplastic without the initial costs of
several tools and the hassle of post-
production assembly. The adhesion
achieved, between the LSR and
thermoplastic, when using this process,
is unbeatable and only further enhances
the performance of the end device.
What trends should manufacturers
prepare for?
Whether it be wearable medical
technology or advances in drug delivery
systems, the medical industry is an ever-
evolving and highly-innovative industry,
and with the unique material
characteristics of LSR the possibilities
for this incredibly versatile material are
endless!
