Silicone Promotion Gifts Thermal Stability, Cold Resistance

Dongguan Tufeng Rubber Co.,Ltd | Updated: Aug 07, 2017

Silicone products began to be used in more and more areas, precisely because the silicone non-toxic, tasteless, high temperature characteristics determine his use of the field. Different silicone products production process is different.

The following is a description of the six major products of silicone products:

Molding, this production process is the most common. Mainly by the mold with the completion of the shape of the mold to determine the shape of silicone products. Molded silica gel products are usually through the high temperature mold into the vulcanizing agent after adding solid silica gel raw materials through the vulcanization machine to exert pressure,Silicone Promotion Gifts high temperature sulfur into solid forming, molding silica gel hardness is usually 30 ° C-70 ° C this production The process is simple and suitable for all silicone products.

This process is relatively high quality requirements, is a combination of liquid silicone and plastic. Its products show good thermal stability, cold resistance, excellent electrical insulation properties, combustion will not produce toxic substances. Therefore, it is an irreplaceable material in the production design of health supplies, automobiles, baby products, medical supplies, diving supplies, kitchen utensils and seals.

Extrusion molding, extrusion silicone products are usually extruded through the extrusion of silicone molding machine, the general shape of the extruded silicone is a long, tubular can be cut, extruded art out of the product shape is relatively simple, mostly shape. Silicone tube in the medical,Silicone Promotion Gifts mechanical equipment used in the field more widely. Can also be used for packaging materials from the role of caching.

Silicone rubber in the addition of white carbon black, silicone oil and other kneading made of kneaded rubber and then pressed out of the sheet. The film produced by calendering, its longitudinal and transverse physical and mechanical properties are significantly different, this phenomenon is calendering effect. Specifically, the longitudinal tensile strength of the film is larger than that of the transverse direction. The transverse elongation of the film is greater than that of the longitudinal direction, and the longitudinal shrinkage of the film is larger than that in the transverse direction. The calendering effect is the result of the orientation of the macromolecule and the needle in the compound, and the flake compound is calendered in the calendering process. Calendering effect of the size, and the composition of the compound, rolling temperature, speed, speed ratio and so on. For larger products, such as silicone film, silicone board.

Irrigation or infusion mode of operation: irrigation or perfusion mold, is used for relatively smooth or simple products, no mold province save time, that is,Silicone Promotion Gifts you want to copy the product or model, with plastic sheet or glass plate Wai Up, the vacuum will be drawn directly into the top of the product, until the silicone drying molding, remove the product, the mold on the molding (Note: the general use of relatively low hardness of the silica gel mold, so stripping easier Will damage the silicone mold inside the product.) Is a solid and liquid combination, the use of products such as mobile phone sets, luggage sets and so on.

Rapid vulcanization; strong adhesion; good mobility, easy to defoaming. Excellent heat stability and cold resistance (using temperature -60 ℃ ~ 200 ℃) after forming a good permeability, heat resistance, and a certain tensile strength; non-slip Excellent performance; no pollution; low hardness; glue bonded firmly. High tear strength; high transparency; good tensile properties. Wear, washable,Silicone Promotion Gifts high temperature; three-dimensional high, smooth fabric, soft, excellent texture, good flexibility, washable and dry cleaning. Applied to the cloth above, the role of anti-aging. Such as silicone gloves, rain boots and so on.
