Odorless Medical Grade Liquid Silicone Rubber For Medical Grade Platinum Cured For
Our LSR 6250-50YH liquid silicone rubber is a two-component
material, and the silicone rubber includes Part A base silicone and
Part B curing agent. The Part A base silicone and Part B curing
agent can cure at room temperature by an addition reaction, it can
be heating during the action, the higher temperature, the faster
curing. All LSR are platinum cured (vulcanized) materials which are
mixed in a 1: 1 ratio by weight.

Here is a look at the LSR molding process:
1. LSR A + B components typically come in a 5-gallon pail or
55-gallon drum. A process controlled pumping kit presses down on
the buckets to force the material into a static mixer and feed into
the injection unit.
2. Then, streams of pigment can be added and controlled. In the
injection, press material will be mixed together additionally with
a screw and pushed forward to create a “shot” of material, or the
amount needed to fill the mold.
3. After the material is injected into the mold, it will then stay
clamped together to cure the LSR. Then, either an operator or a
robot will remove the cured product from the mold
Our offerings also include products that meet FDA, BFR, and USP
class 6 requirements or contain low levels of low-molecular-weight
The material feels soft on the skin, which makes it an obvious
choice for devices that contact the body.
Because of the outstanding properties, LSR 6250 - 50YH® infant
liquid silicone rubber is particularly suitable for the following
elastomeric articles: pacifiers, baby teats, baby bottles, baby
bowls, baby toys, baby rattles, teethers, grabs, baby spoons, food
feeders, breast pump, Nubra, baby bibs and baby nipples, etc.
LSR 6250 - 50YH® Liquid silicone rubber obtained the following test certificate:
