Silicone rubber products are widely used in medicine
Silicone
rubber products have been widely used in the medical category, first because of
their properties and structural characteristics, such as for medical
pharmaceutical seal stopper has surely elastic demand, still can keep the
original conurbation and air tightness after acupuncture, and not have debris
fell off. But today the nature of the rubber is difficult to meet the medical
needs, the demand of rubber modified or adding some reagents to change its own
deficiency, in order to meet the application in medical treatment.
Silicone
rubber products is a high molecular weight linear polyethylene organic siloxane
as root, increase the specific components, and in accordance with the technical
requirements must be processed and made state must strength and elongation of
rubber elastomer. Used as medical materials of silicone rubber products, high
temperature resistance, resistance to oxidation, hydrophobicity, flexibility,
high permeability, resistance to ageing transparency, languid is lazy, arrange
with the body and blood not good adhesion, biological adaptability, non-toxic,
tasteless, and don't cause cancer, and a series of excellent properties.
Silicone
rubber products as a function of excellent medical polymer materials, whether
in the rubber industry is still in the medical category are subject to the
attention of the professionals. The reason is that the top of the list, medical
materials, used as rubber high technical content, low cost, high added value
and economic benefit is very considerable, Second, the utilization of the
medicinal properties of silicone rubber products. Can solve many problems on
the medical skill, but also can make the patients obtained satisfied effect;
Third, rubber origin widely, easy to produce and fine machining, has good
social benefit and economic benefit.
Silicone
rubber products of fetal head attract: convenient operation, use safety,
according to the deformation of fetal head size, attract the fetal scalp don't
get sucked up, can prevent scalp hematoma and intracranial injury, can greatly
reduce childbirth pregnant mother giving birth in the suffering.
Silicone
rubber products artificial blood vessels: with special physiological functions,
to do with the human body "intimacy" the body does not exclude it
must have time, will arrange with the body case up completely safe sex is very
outstanding.
Tympanic
membrane repair piece of silicone rubber products: the thin and soft, smooth
finish and toughness are outstanding. The ambition of patching eardrum data,
and easy to operate, works well.
Artificial
trachea and lungs in addition silicone rubber products, artificial bone,
silicone rubber products duodenal tube and so on, results are very ambitious.
Because
foam silicone rubber products with high thermal stability, excellent
insulation, insulation, moisture resistance, shock resistance, especially under
the high frequency of good vibration resistance, so it is a kind of ambition of
lightweight packaging materials. Fly for a variety of electronic components,
instruments, appearance, body equipment wheel can have "moisture, shock,
anti-corrosion of" three proofing "maintenance effect. In addition
can also do insulation sandwich filling materials and salt fog in the atmosphere
and floating materials and sealing materials. Foam silicone rubber products in
medicine can also be used as filler, repair and orthopedic surgery above
information.
Two-component
condensed type room temperature vulcanized silicone rubber products
vulcanization time primarily depends on the type and dosage of catalyst and
temperature. Catalyst the faster the curing, the shorter the placed time.
Placed at room temperature, the time is usually a few hours, to extend the
placement of rubber, available cooling method. Two-component condensed type
room temperature vulcanized silicone rubber rafter to reach completely cured at
room temperature demand time of a day or so, but under the temperature of 150 ℃ needs
only 1 hour. After using the accelerator gamma amino propyl triethoxy silane
synergistic effect can significantly advance the curing speed.
Bicomponent
RTV silicone rubber products can be in 65 ℃ ~ 250 ℃ temperature range insist for a long time
of flexibility, and has excellent electrical function and chemical stability,
water, ozone resistance, weathering resistance, combined with the usage
briefly, technology applicability, therefore, widely used for sealing and
molding materials. Various electronic and electrical components are coated with
room temperature vulcanized silicone rubber products, potting, damp-proof
(maintenance effect. Such as anti-corrosion, shock can progress and stability
parameters function. Bicomponent RTV silicone rubber products is suitable for
deep do potting materials with fast curing time, this is the place that is
better than that of one-component room temperature vulcanized silicone rubber
products.
