Candle moulding silicone rubber applications Candle moulding silicone rubber is primarily intended for poly resin crafts, PU crafts, decoration ornamental crafts, PU resin crafts ,gypsum crafts ,unsaturated resin crafts, lighting and candles crafts ,plastic toy , stationery gifts crafts industry, a large statue Buddha, relievo furniture, furniture decorative materials, statues Buddha, artifacts copied, building decoration materials, large-scale cement mold, artificial fossils Factory, Europe component factory, simulation landscapes, animals and plants sculpture, sandstone crafts and so on. Candle moulding silicone rubber features description Candle moulding silicone rubber is white or red flowing liquid with general hardness of 22-50A°after curing. Molding liquid silicone rubber is a kind elastic silicone rubber which features with resistance to deformation, high-temperature, acid-alkali and expansion as well as high reproduction times, good tensile strength, tear strength and elongation. Candle moulding silicone rubber operations If the customer wants to make large decoration ornamental crafts products and large size molds, the mold should be made of liquid silicone rubber with high hardness. On the contrary, if the mold with fine and precision patterns, it should be made of liquid silicone rubber with low hardness. The amount of the curing agent depends on the actual requirements of the customer. If molds requiring fast drying and demold, more curing agent is needed; contrarily, if molds requiring slower drying and demold, less curing agent is needed. 1. Why could the silicone mold be reused only for a few times?It can be due to the following reasons:a. Adding too much silicone oil in to silicon rubber. Silicon oil is an additive which destroies the molecular weight of silicone rubber and reduce the tension and tear strength.b. Using the silicon rubber with a high hardness to make molds for small sized products with delicate and intricate designs and the silicon rubber with a low hardness to makes molds for large sized products with simple designs. 2. Why does the silicone mold get burnt out?This consequence happens only because you have left out the important notes when using unsaturated resin materials to produce your products. The unsaturated resin produces great heat when added the curing agent. So you must demould the product within 3 minutes to avoid this problem. 3. Why does the silicone mould appear to be dry outside but wet inside? Because molding silicone rubber is a kind of condensation silicone rubber, which get solidified after absorbing moisture from the air. In order to provide a significant shelf-life for the silicon rubber, we will dry out the water in the silicon rubber.Solution: Add 0.05% water into the silicon rubber and Stir over a low speed briefly when you use it.
