LSR LIQUID SILICONE
Injection molding liquid silica gel (LSR) is a new kind of organic silica gel material, which is non-toxic, tasteless, weatherproof and chemically inert. This kind of silica gel has low viscosity (it has certain fluidity and irreformability before vulcanization) , uses Elmet rubber feeding machine to mix AB agent, Wittmann Battenfeld silicone gel machine to mix two groups of AB agent and inject mould, then rapid vulcanization, injection molding products.
High and low temperature resistance (use temperature from -40 ° C, +240° C, cold and heat cycle test, the product is not yellowing)
Good weather resistance (UV resistance)
High light transmittance
High degree of automatic molding
Good waterproof Good electrical characteristics
Elastic, malleable Safety recognition (FDA, NSF,Mil,UL)
There are no by-products The product has a long service life during vulcanization
Why use optical grade silicone
Today, the development of cutting-edge high-power LED technology is facing new challenges. The new generation of LEDs will need to maintain their optimum luminescence and lumen values over time and be able to be used in micro-structural design at compact sizes; however, these requirements present a major challenge to the current optical plastic components. On the contrary, optical silica is the material that can provide optical transparency, durability, and design hyperboloid and free- form surfaces.
The advantageous properties of silicone gel materials
High light transmission Can meet the design requirements of transparency, atomization, and astigmatism, with excellent results.
Luminous flux loss In the hot and humid environment, can maintain a variety of lens projection accuracy.
Durability UV resistance and crack resistance is very good; high temperature stability, showing that it can maintain a good long-term luminescence, and will not cause problems such as heat-resistant plastic yellowing.

Liquid Silicone Rubber LSR
LSR is a two-components liquid silicone rubber used to produce elastic items with the injection moulding method.
For example its molecular structure is characterized by bonds where the carbon is substituted with silicon; it follows that both the technology for its transformation and the kinds of its uses are peculiar..
The products in LSR are created by the chemical reaction of two different gelatinous components.
The cross-link process, similar to the vulcanisation one, can be speed up or down by the temperature, but it’s always irreversible as soon as the two components come into contact each other.
Therefore the LSR cannot be recovered and cannot be moulted with the same technology used for pastes and mixtures able to be vulcanized.
This material is then transformed using specific injection machines which let to obtain the best results.
LSR Characteristics
The products vulcanized with the Liquid Silicone Rubber have the following characteristics:
• Excellent high temperature resistance +250° C
• Excellent low temperature resistance and flexibility – 60°C
• Very good thermal stability
• Excellent resistance to ageing and great stability to ozone and UV rays
• Very good dielectric behaviour in a wide temperature range
• Very good stretch characteristics inside the provided hardness range
• Very good stretch against breaking
• Very good ultimate tensile stress
• Physiological independence
• Inertless (no taste or smell)
• Very good size stability
• The products satisfy the BGA, FDA, KTW rules regarding the contact with food.
SPECIALIZED ITEMS:
Applications for oil resistance
Electrical conductivity
Fuel resistance
Medical contact
Fluorurate silicone
Colours
Generally the Liquid Silicone Rubber are transparent; they can be coloured adding a third component, a couloring paste, into the mixer.
Now it’s possible to produce details in the following colours: RED, WHITE, BLACK, GREY, GREEN, SKY-BLUE, YELLOW; other colours can be custom made for special items.
