Lifecasting Silicone

Lifecasting Silicone

The lifecasting silicone is characterized by good electrical property and chemical stability. It is water and weather proof, non-corrosive, non-toxic, tasteless, biological aging resistant, and physiologically inert, and allows easy pouring and operation as well as complete vulcanization. The silicone can meet mechanical strength requirement even if the hardness is low. Suitable for making printing pads, the lifecasting silicone provides low linear shrinkage and can keep its original hardness after long time use.

Hence, the lifecasting silicone is especially suitable for lifecasting and printing pad making. For instance, it can be used to make soft silicone products such as sex toys, body organs, breast enhancers, shoulder pads, and more, in addition to life casting. The silicone, also commonly found in the field of pad printing, is applicable to making silicone pads which are used as a pattern transfer carrier for plastic toys, electroplated products, electronic products, and trademarks, etc. The lifecasting silicone is a kind of room temperature vulcanizing addition cure silicone rubber, and is a kind of almost colorless translucent fluids. So, we can offer lifecasting silicone with different colors to satisfy the varied demands of our clients.

Technical Data of the Y805 Lifecasting Silicone

Model Before curing
Appearance Dynamic viscosity (Cp) (25℃) Shore A0 Pot life (mins) (25℃) Demould time (hrs) Tensile strength (Mpa) Tear strength (kn/m) Elongation at break (%)
Y805 Yellowish translucent fluid, without apparent mechanical impurity A: 27000±5000 B: 700±200 A+B (1:1) 4000±1000 A+B(1:1) 5±2 A+B(1:1) 30±10 A+B(1:1) (25℃) 4±1 ≥0.5 ≥10 ≥500
Note 1. Keep sample at room temperature for at least one hour before you take a proper amount of it for testing. Put A and B under room temperature for one hour respectively, and then mix them evenly in the ratio 1:1. Test the viscosity immediately. (For the fast cured type lifecasting silicone, delayed action activator is required.)
2. Thickness of cured test sheet should be no less than 6mm.
3. Mix A and B evenly at a ratio of 1:1 under room temperature, and record the time when crosslinking reaction occurs in the mixture.
4. The test sheet is initially vulcanized with the thickness at least 2cm, and it can be restored after extrusion. The cured sheet is made to offer standard mechanical property, which is tested by an electronic universal testing machine.

Packaging, Storage and Transportation of Y805 Lifecasting Silicone
1. The lifecasting silicone is packaged in clean, dry and sealed steel cans or drums. Component A and B should be packed separately. Usually it is packed in 5kg/can, 20kg/drum or 200kg/drum.
2. Keep the product in a cool and dry place. It should be specially noted that the lifecasting silicone should not touch or mix with nitrogen, sulfur, phosphorus, tin, and lead compounds, or metal organic acid salts. Otherwise, the catalyst will be poisoned, and then the silicone can not be cured or just partially cured.
3. The lifecasting silicone is NOT subject to the provisions of the IMDG code. The shelf life is 18 months from the date of production. And it can still be used after expiration when it is retested and proves to be acceptable.
