White silicone plates They are valued mainly in the food, medical and pharmaceutical industries. They have hygienic certificates of the National Institute of Hygiene and FDA certificate. This guarantees safe use in contact with food intended for human and animal consumption, which is why agriculture also uses this type of plates.
Milk silicone plates – application
Due to the wide temperature range at which this type of rubber can be used, it is also popular in light, medium and heavy industries. Products made of silicone plates are used where other types of technical rubbers fail due to the risk of degradation of their structure, and thus – damage to the material and its properties. White silicone plates are widely used , primarily as custom-made gaskets. There are several types of them, they can be used as:
- H-type gaskets, which are most often used to seal windows. They play several roles there, primarily they affect thermal insulation, which limits heat loss inside the building, as well as limiting the penetration of moisture and noise reduction. White silicone plate gaskets fulfill this role perfectly, as they are resistant to solar radiation and harmful environmental conditions, such as moisture / steam / dust. White silicone has a very flexible temperature range, they are characterized by high hardness in the range from 40 to 90 ShA and are resistant to frequent opening and closing of the window. In addition, their color perfectly matches the window, ensuring an aesthetic appearance.
- D-type gaskets, which are primarily used as a door cover. They are usually used for self-assembly, so they are made of silicone plates with a low hardness, about 20 Shore A. Thanks to this, the silicone perfectly fits the surface and fills the gaps.
- universal seals for various edges.
In addition, the highest quality milk silicone plates They are used for the production of silicone hoses, which are used in various industries, from machinery and automotive, to food and pharmaceutical.
Milk silicon sheets and other types of technical rubbers
Although they are made of the same material as rubber, and joining polymers is done in the same way, the milky silicone plate and technical rubbers differ in their chemical composition, which drastically affects their properties and application. Below is a comparison of several types of rubbers with silicone products:
- SBR rubber – resistant to abrasions and structural disturbances. Neutral to moisture, alcohols, acids and bases. Their variant NR / SBR, just like the milk silicon plate, has PZH approval and can be used in food production. However, unlike silicone, it should not be exposed to sunlight, as UV radiation significantly damages it. They are also sensitive to natural greases and oils that do not affect the use of elastomer plates. Moreover, they have a smaller temperature range for continuous and short-term operation.
- NBR rubber – resistant to all kinds of lubricants, engine oils, propane, butane and hydraulic fluids. It doesn’t bother her high pressure . Unfortunately, the operating temperature in oil is between 70 degrees and 100 degrees Celsius, so it is not suitable for use in the temperature range in which silicone plates can be used.
- EPDM rubber – has the properties most similar to silicone plates. Resistant to shocks and moisture, it does not react with acids and esters, so it is not harmed by most corrosive substances. Exposure to sunlight also does not affect its quality. However, like the previous rubbers, it retains its properties only at lower temperatures, up to 130 degrees Celsius.
As you can see, listed rubber compounds are components of universal rubber products, however, if we want a material resistant to high temperatures that will retain its properties and at the same time be a guarantee of safety, definitely they will work better silicone plates .
Silicone plates – dimensions
Depending on the degree of hardness, the silicone plate may have a different dimension. Due to the extreme hardness, such silicone plates only have one dimension, 500×500 mm. As for the intermediate hardness of silicone, the most standard dimension is a roll of 1200×1000 mm. Like other color variants, the milk silicone plates have different thicknesses. The most common ones are: 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 8 mm, 10 mm. Each client has different needs, so silicone plates are also cut to size, on an individual order.
