Technical parameters of silicone products
Ratio of silicone vulcanizing agent. Silicone rubber is the most common two component vulcanized silicone rubber. When not in use, silicone rubber is divided into two parts: colloid and vulcanizing agent. When in use, it can be operated by mixing evenly in a certain proportion. In general, only the weight of the colloid needs to be considered, and in special cases, the weight of other additives of silicone needs to be considered. For example, when using transfer printing silicone, the proportion of vulcanizing agent needs to be calculated based on the total weight of silicone and added silicone oil. C-8E (vulcanizing agent) is a transparent, environmentally friendly silicone vulcanizing agent used for molding and vulcanization of silicone rubber products. It is used for transparent, semi transparent, and high-quality products, as well as for ordinary silicone processing products.
C-14 food grade odorless vulcanizing agent C-14 is a newly developed odorless vulcanizing agent by our company, used for the molding and vulcanization of silicone rubber products. Used in medium to high quality products, especially suitable for producing silicone miscellaneous products. Suitable for colored parts and transparent, white products, C-14 can be odorless after one sulfur addition. Second stage vulcanization is better (160 ℃; 20 minutes). This product is flammable. When mixing, please first add two kilograms of silicone vulcanizing agent and the same proportion of bridging agent, and then quickly add the remaining raw materials to avoid ignition.
C-15E environmentally friendly vulcanizing agent C-15E is a transparent rubber like environmentally friendly anti yellow vulcanizing agent used for the molding and vulcanization of silicone rubber products. Suitable for medium to high quality products, as well as general silicone processing products. Used for transparent or white parts, it can ensure that the product does not turn yellow after four vulcanizations (or baking at 200 ℃ for 1-2 hours after two vulcanizations).
C-20E anti yellowing vulcanizing agent C-20E is a semi transparent colloidal silicone anti yellowing vulcanizing agent used for molding and vulcanization of silicone rubber products. Suitable for medium to high quality products, as well as general silicone processing products. Used for transparent or white parts, it can ensure that the product does not turn yellow after five vulcanizations (or baking at 200 ℃ for about 4 hours after secondary vulcanization). It is suitable for colored parts to resist yellowing and ensure that colored parts do not change color after multiple vulcanizations.
H-10 silicone rubber internal demolding agent This product is an internal additive specifically designed for high-temperature vulcanized silicone rubber demolding. It is easy to disperse when added, and adding a small amount of this product can significantly increase production and fully ensure the quality of the product. This product is widely used in complex shaped silicone rubber products such as buttons.
FY-31 silicone rubber treatment agent FY-31 silicone rubber surface treatment agent is a primer specially used for Double-sided tape of silicone rubber back, which can be divided into quick drying and slow drying types. It is selected according to different production processes of the product. Apply it on the high-temperature rubber sheet, and then stick Double-sided tape to make the Double-sided tape stick tightly to the rubber sheet. After drying, this adhesive is non-toxic, odorless, and resistant to high temperatures
Y-21 silicone rubber shrinkage agent This product can reduce the size of silicone rubber products when used in high-temperature silicone rubber, without affecting other properties of silicone rubber (such as yellowing, mechanical properties, etc.). At the same time, this product is easily dispersed when added and does not produce white spots. It is widely used in silicone rubber buttons, sealing rings, and other miscellaneous products. Double two four vulcanizing agent has good yellowing resistance, high transparency of the product, less addition, less frost spraying, and low odor, making it suitable for producing high transparency
Silica gel is a kind of amorphous silicon dioxide, and the dust content in the workshop should be controlled to be no more than 10 mg/m3. Air exhaust should be strengthened, and masks should be worn during operation.
The superior performance, coupled with the fact that silicone is a non petroleum product and does not rely on increasingly scarce petroleum resources, has made silicone products a substitute for similar plastic products.
Ratio of silicone vulcanizing agent. Silicone rubber is the most common two component vulcanized silicone rubber.
Viscosity. Explanation of technological terms: The volume characteristic of a liquid, quasi liquid, or quasi solid substance that resists flow, that is, the internal friction or flow resistance between molecules when flowing under external forces. Usually, viscosity is directly proportional to hardness.
