Features and Properties	Silicone rubber	Polyurethane resin
Modification ability	Better modification ability and good electrical insulation ability by adding different additives	Could be modified its own thermal conductivity based on different products potting
Resistance for high and low temp	Excellent resistance for temp, do not crack and stay good elasticity under temp from -60℃~200℃; better for working under harsh environment	Easy crack especially under high and low changing temp; thereof, effect the moisture resistance
Hardness and flexibility	Lower hardness, better flexibility	High hardness, very stiff, less flexibility, therefore, less anti-shock ability
Heat and corrosive substance release	Do not release heat and corrosive substance during curing, more friendly and protective for  Electronic Components	Will release more or less heat during curing
UV-proof and anti-aging	Better UV-proof and anti-aging
Adhesive ability	Slightly less than Polyurethane resin under normal condition, but could be largely increased with premier	Better than silicone rubber
Applications	Excellent materials for electronic parts potting, especially for precision components potting and protection	Excellent and economic materials for electronic parts potting
Cost/Price	Price a bit higher than polyurethane resin

The shelf life of a material in its liquid state refers to how long it can sit on a shelf before it begins to lose its ability to function normally or sets up entirely in the container.You should know how long you can expect a material to last on the shelf to protect your material investment.

Normally, Inno Silica tin cure siilcone rubber shelf life could up to 12 months under room temperature with sealed; Platinum cure silicone shelf life could up to 15 months and even longer. 

Inno Silica has full set solutions for shelf life issue. If you have any trouble, welcome to consult with us for details: inno.silica@gmail.com

Some Platinum cure silicone is fumed made. When the silicone stored and stayed unused for long, the silicone may become inertia. If the silicone dose not get polluted, the situation of some platinum cure silicone become inertia is quite normal and is quite easy to "wake it up". This situation does not mean the silicone reacted and structured. If you come accrose to this situation, please contact with Inno Silica (email: inno.silica@gmail.com). We could provide one easy method to help you solve this problem.

Most of time, tin cure silicone still could be used even pass the expiry date. But sometimes,If silicone over the expiry date too long,silicone may get thicker or could not flow. How to do if silicone pass the expiry date for long, and could not flow? Actually, the silicone at this situation is still usuable after get some treatments.

Inno Silica has several treatments for solving this situations. Different treatments should be based on different situation of silicone, like how thick the silicone is; and how the flowability of silicone; how long the silicone passed the expiry date.

Clients could contact by this email: inno.silica@gmail.com to submit the situation they come accross to. We will provide full set of solutions according to the actual situation without destroying the properties of silicone rubber and increase your extra cost.
