High transparent silicone mold, silicone food grade certification, food-grade liquid silicone

 High transparent silicone mold, silicone food grade certification, food-grade liquid silicone applications: not only can fit the mold rubber RTV-2 applications, but also especially suitable for ice carving salt food molds, silicone cake molds, chocolate and sugar confectionery replication silicone food mold making, it has a food certification, nontoxic, odorless, has a low viscosity, strength also good, better mobility, but also very suitable for precision complex pattern of the original copy. High transparent silicone mold, silicone food grade certification, food-grade liquid silicone Features: Food is a two-component silicone molds and molding silicone AB, A: B = 1: 1; This series of products in addition to the two-component condensation-type RTV advantages of silicone rubber, but they also have a very low viscosity and linear shrinkage (shrinkage of 0.1% or less) curing process does not release low molecular weight byproducts, when curing is from top to bottom, from the inside to the outside into the synchronous, vulcanization can be deep, there is no reason not small molecule byproduct clean except under certain conditions (such as closed, at high temperature) so that the mold back stick degradation phenomenon, and add molding rubber has better hydrolysis resistance, high temperature, Food for silicone baking molds, size, shape, mold and production complex for large plaster, stone, cement and other mold. Technical parameters: Type / Item Y640A / B color (A component) translucent (color adjustable) Color (component B) translucent A, B component addition ratio 1: 1 AB mixing Viscosity cps 4500 operating time (25 ℃) min 20-30 curing conditions (℃ / h) at room temperature / heating density / g · cm-3 1.18 Shore hardness (A) 20-50 crack elongation /% ≥340 tear strength / KN · m- 1 ≥25 tensile strength / Mpa ≥5.0 line shortening /% 0.1 High transparent silicone mold, silicone food grade certification, food-grade liquid silicone with Instructions Step: Mixed: component A and B component by component ratio 1 : 1 weight ratio, mixing can be manually or mechanically operated, stir evenly. Step Two: degassing: A, B component after mixing evenly, plastic mold filling should be carried out before the row of vacuum bubbles. When a small amount of use can be carried out in a vacuum desiccator, in vacuo -0.08MPa, rubber volume can be increased 4-5 times (foam), and therefore, the volume of the container should be degassed 4-5 times more than the volume of glue, After a few minutes gel volume returns to normal, no bubbles escape when the surface (about 10 minutes) to an end. The third step: Surface Disposal: The material surface of the mold surface or potting compound to be in contact with water or detergent can be used as a release agent, such as Vaseline. Step Four: curing and stripping: Mixed degassed plastic material placed 120 ± 5 ° C curing bake 30 minutes, 60-70 ° C bake for 1-2 hours curing, room temperature curing time is 5-6Hr, cured temperature and time according to the actual operating conditions.
