Food Grade Silicone Rubber molding Product Description:

Food Grade Silicone Rubber is a two-part-kind liquid silicone, which belongs to

food-grade silicone, can be cured at room temperature, and mainly used for mold

making of food-grade molds, jewelry casting, tire molding, rapid prototyping, vacuum

foaming. It also suits any condensation silicone’s application for molding, etc. With

appropriate hardness, good tensile and tear strength, and excellent resistance to

deformation, finished silicone molds have not only a durable life but also good Performance.

Food Grade Silicone Rubber Features:

1. Amazing fluidity and easy to operate

2. Platinum-based, food-grade silicone (environmental friendly, odorless and

non-toxic)

3. Delicate design available

4. Mixing ration: 1:1, easy to mix

5. Easy de-moulding

6. Excellent tension and tear strength

7. High performance in duplication

8. Shrinkage is almost zero (below 0.1)

9. Excellent resistance to weather, temperature, aging, acid and aging-proofing.

10. High resistance to high temperature and aging(resist -60℃ to 250℃)

Food Grade Silicone Rubber Operation Method:

1. Stir part A (100g) and part B (100g) with 1:1 mixing ratio evenly. Then get the

mixture for vacuum-pumping. (If there is no vacuum machine, you can just pour the

mixture slowly from the corner so that less bubbles caused)

2. Enclose the product (the original model) with four plastic plates or wooden plates.

3. Clean your products and brush a layer of release agent (detergent or soap water)

on your product.

4. Pour the mixture into the model frame with correct mixing ratio.

5. After about 3 to 5 hours, when the silicone is cured, remove the original model,

and then you get a finished addition cured silicone mold.
