1、 Characteristics of High Transparent Mold Silicone
1. Good transparency and aging resistance;
2. High hardness, no deformation;
3. Low shrinkage rate and high precision;
4. Has elasticity and good tear resistance.
2、 Chemical Principles of High Transparent Mold Silicone
From the principle of organic silicon, there are two types: condensed silicone and additive silicone. The biggest difference between the two is the difference of curing agent and high temperature resistance and aging resistance time. The addition silica gel is a platinum catalyst curing agent, which can resist high temperature and aging for a long time.
3、 The Use of High Transparent Condensed Mold Silicone
Widely used in the replication of POLYSTER, EPOXY, polyurethane molded products, PU foam resin decorations and crafts, antique furniture, ceramics, craft candles, gypsum crafts, European components, large sculptures, cultural relics replication, architectural decoration, relief furniture, imitation marble, artificial imitation natural stone, shoe molds, lighting arts, human statues, imitation copper crafts, model facilities Simulate mold manufacturing in many industries such as Shanshui.
4、 Characteristics of condensed mold silicone
Two component room temperature vulcanized silicone rubber has excellent flowability and good operability. It can be operated after adding a curing agent of 2-3% at room temperature, and can still be operated for 30 minutes. It will be generated after 2-3 hours. It has an elastic silicone mold that is not deformed, resistant to high temperatures, acid and alkali, and does not expand. It is a replica and precision mold manufacturing for handicrafts, resin handicrafts, lighting, candles, and other products.
5、 High transparency addition molding mold silicone usage
Mainly used for precision mold manufacturing, such as the production of precision molds for polyurethane, epoxy resin, and other molding materials. It can also be used for the surveying and mapping of chemical building materials, carbon fiber composite materials, and machine components with stable scale requirements. It can also be used for the decoration and handicraft reproduction of POLYSTER, EPOXY, and PU foam resin, as well as for the production of art candles and gypsum molds. It can also be applied in the mold manufacturing of furniture and electronics industries, The product has high transparency and good demolding performance. It can be seen whether there are defects such as bubbles in the injected material inside the mold. It can also be used to make high hardness and long service life transfer printing adhesive heads.
6、 The characteristics of silicone in addition molding molds
The addition molding silica gel can be used for a long time in the temperature range of - 65 ° C-350 ° C, and maintains its soft and elastic properties. It has excellent electrical properties and chemical stability, water resistance, ozone resistance, weather aging resistance, non corrosive, physiological inertia, non-toxic and tasteless, low linear shrinkage, high transparency, good demoulding performance, easy operation and other characteristics.
