Plaster mold silicone?

The hardness of plaster mold silicone rubber refers to the amount of pressure required to form indentations on the silicone rubber. The higher the hardness, the greater the pressure needed. Plaster mold silicone can be used for a variety of applications, including medical devices, food-grade products, and cosmetics.


Silicone product hardness selection tips?

We use silicone materials to make different silicone products, the hardness of the silicone chosen, and the operation process is different. Take liquid silicone material, for example, the hardness of silicone can be as low as 0 degrees or less, as well as 0 degrees to 60 degrees. The unit of silicone soft hardness is (Shore A). If you require good tear resistance hardness, you can choose between 10-45A, depending on what products are used. There are a variety of silicone rubber products on the market, each with a different level of hardness. It can be difficult to decide which product is best for your needs, but by reading this article you will be able to choose the perfect silicone product for yourself. Dental mold silicone Dental mold silicone rubber comes in a wide range of hardnesses, from very soft to very hard. The hardness of the material will determine the level of detail that the mold can capture, as well as the durability of the mold. Softer silicones are often used for intricate designs, while harder silicones are better suited for more robust molds. The type of silicone used will also determine how long it takes to set; softer silicones will set faster than harder silicones. Ultimately, the decision on which silicone to use will depend on the specific needs of the project. For those who do not understand silicone materials, the physical softness and hardness of silicone products are half-understood psychologically, looking at the appearance of the product is no change, need to understand the relationship between the formulation and various physical properties to understanding. However, for customers who first come into contact with silicone rubber products, there will be uncertainty about the softness and hardness of the silicone parts we use if they do not understand the softness and hardness of silicone. Therefore, it is easy to lead to the demand for silicone rubber products in the custom silicone products, do not know how the hardness to better fit with the product, so the latter will have to be adjusted to the silicone hardness. Candle silicone The hardness of the candle silicone is an important consideration when choosing a candle mold. The hardness of the silicone determines how easy it is to get the candle out of the mold. For example, a softer silicone will produce a more detailed candle, but it may be more difficult to release. A harder silicone will produce a smoother candle, but it may break or fracture more easily. When choosing silicone for candles, it is important to consider the intended use of the candle and to choose a hardness that will produce the best results. Different silicone rubber products have their unique properties and process requirements, such as silicone seals for silicone product manufacturers, silicone accessories, etc. The most suitable polymer can be selected for blending. In the softness and hardness to achieve a close fit sealing shock absorption, waterproof and oil-proof and other effects, the physical properties of the softness and hardness of silicone products.


How do you make silicon rubber?

Homemade silicone rubber is made by melting silicone until it turns into rubber form. Professionally, there are several ways to produce silicone rubber, most are a mixture of silicone, oxygen, carbon and hydrogen.


HTV high-temperature vulcanized silicone rubber three molding processes?

HTV high-temperature vulcanized silicone rubber is a kind of silicone product, with excellent high and low-temperature resistance, ultraviolet resistance, radiation resistance, weather resistance, electrical insulation, high breathability, physiological inertia, low compression permanent deformation and fatigue resistance, etc. Therefore, HTV high-temperature vulcanized silicone rubber is widely used in aviation, aerospace, electronics and electrical, light industry, machinery, construction, chemical industry, medicine, daily necessities, and other aspects, the following will give you a detailed explanation of the three high temperature vulcanized silicone rubber molding process. According to the types of high-temperature liquid silicone rubber on the market at present, one is solid silicone and the other is liquid silicone. The molding of solid silicone can be divided into molding and extrusion molding, and liquid silicone is mostly injection molding. Molding Molding is also called hot pressing, that is, in the high-temperature mold add (double 25 or double 24) a silicone platinum vulcanizing agent of the compound through the plate vulcanizing machine pressure, high-temperature vulcanization molding. The molding process is the production process of solid silica gel. The upper and lower two modules are combined, and a mold core is placed in the middle, so it is called the molding silicone rubber. The main production process of molded silicone rubber products is the processing process of silicone rubber products formed by heating and pressurizing the silicone rubber raw materials in the closed mold cavity. Usually, the silicone raw materials are evenly mixed into the mixing machine, and the mold is moved into the vulcanization molding machine. Then the closed mold pressure, molding and curing or vulcanization, and then the release of silica gel products, this process is suitable for thermosetting materials processing. The hardness of molded fumed silica gel is usually 30-70A (Shore hardness). In the process of rubber mixing products in the silica gel factory, the raw rubber is first added to the double roll rubber mixer or closed kneader. Gradually added white carbon black, silicone oil, and other additives repeatedly refining. According to the different fillers and additives, the performance of silica gel is also different. This process is relatively low cost, high yield, and widely used. It is used for monochrome silica gel products. It can also be used in two-color and two-hardness products or multi-color and multi-hardness products, but the structure of the product is not flexible, or limited. It can also be applied to plastic and metal packages, the same structure is not flexible, and the package has temperature requirements, the general requirement of the package to withstand 180 degrees Celsius without deformation. The shape of the injection molding process determines the shape of the molded silicone products. Molded silicone products are the most widely used in the silicone industry at present. Mainly used in the production of silicone industrial accessories, buttons, silicone gifts, silicone bracelets, silicone watches, key bags, mobile phone covers, silicone kitchenware, silicone mat, ice grid, cake mold, and so on.

How To Choose a Quality Silicone Rubber Product?

Silicone rubber is a rubber-like material made up of silicone. Other componenets make up silicone rubber such as hydrogen, oxygen and carbon. Silicone rubber can be used on tubes, strips or solid cords. This material can be found in multiple applications around the home in a variety of baking, cooking and food products. The first silicone elastomers were developed in the hopes of manufacturers building a better insulating material for electric motors and generators. Here are some things to look out for when choosing a high quality silicone rubber product: Structure Most silicone rubber products are able to withstand extreme temperatures up to 300 degrees celsius. The properties found in silicone rubber should have the following components: elongation, tear strength, tensile strength and temperature. Some manufacturers try to downgrade properties of silicone rubber products in order to save money in the construction process. While this is good for the manufacturer, it is not healthy or recommended for use by the public. Care is needed when designing products made out of this type of rubber. Silicone rubber also doesn’t react with other chemicals. Special Grades Special grades of this form of rubber is important for getting the most use. Here are some components to look for; steam resistant, electrically conductive, metal detectable, chemical/oil/gas/acid resistant, low smoke emitting and flame-retardant. These are just some of the words or components to look for on the case of a silicone rubber package. Many of the lower grade rubbers don’t have these helpful benefits. A variety of filters can be used in silicone rubber. Liquid Silicone This is another high quality version of rubber (silicone) and is made from pure platinum-cure silicone. Many medical devices use this type of liquid silicone because of its biological make-up and excellent quality. A lack of human contact and medical grade silicones reduces the risk of contamination greatly. This type of rubber is ususally supplied in two parts. One of the parts usually contains platinum catalyst. These components are usually mixed with any ingredients and colors that may be required. Because of this mixing, homogeneous materials lead to consistent and quality parts. These are some of the things to look for when purchasing silicone rubber. The choice is simple to make; it all comes down to the quality of materials and ingredients which make up the silicone rubber.
