Mold making silicone rubber provided by san pin Silicone is two component silicone, also called rtv2 silicone, which will be vulcanized in room temperature when mix part A and part B evenly.
There are two kinds of molding silicone,
one is industry grade, belongs to tin cure silicone and condensation cure silicone, the general mix ratio of silicone and catalyst is 100:2&100:2.5&100:3.
Another one is food grade, belongs to platinum cure silicone and addition cure silicone, the general mix ratio of A and B is 1:1 or 10:1.
Both industry grade silicone and food grade silicone are excellent molding material for making silicone rubber molds, each one has its own advantages.
Advantages
1) Flexible and low viscosity which will copy finest details and patterns from exquisite products.
2) Durable with good strength, top quality to guarantee molding times
3) Easily demolding &Strong tear strength and tensil strength ,
4) Not oily, no bubbles
5) Can resist high temperature 200℃ - 350℃, and low temperature -65℃
6) Low shrinkage less than 0.2%, platinum cure type is less than 0.1%
7) Aging resistance, acid and alkali resistance
8) Platinum cure silicone is FDA certified, nontoxic, odorless
9)long shelf time like 12 months and more
10)adjustable working time and curing time.
Application
Molding silicone is suitable for reproducing and replicating variety of products in large quantity, such us art crafts, furniture, prototyping, architectural elements, garden ornaments, shoe, tire, soap, candle, jewelry, vacuum bag and so on.
Molds silicone rubber is also suitable for making molds for variety of material, such as resin, PU, PVC, polyester, gypsum, plaster, concrete, cement, stone, GRC, wax, jewelry and so on.
How to use the rtv 2 silicone:
1. clean the surface of the prototype.
2. spray some release agent on the surface of the prototype.
3. put it into a frame with bottom ( like a container) and fix it.
4. mix the liquid silicone part A and Part B with certain mixing ratio completely, usually 100:3.
5. if you have vacuum chamber, put the mixed liquid silicone into the chamber and degas for 2 minutes.
6. pour the rtv silicone on the subject in the container fully.
7. after 24 hours. remove the rubber molds from the prototype.
8. rubber mold is done. start using the rubber mold.
