What are the precautions for Methylsiloxane Polymer during use?
When using methylsiloxane and polymer, pay attention to the following things:
First, safety protection is the key. Some components of methylsiloxane and polymer may be toxic and irritating. When contacting, be sure to wear suitable protective equipment, such as gloves, goggles, masks, etc., to prevent it from coming into contact with the skin, eyes and respiratory tract and causing damage. The operation should be carried out in a well-ventilated place. If conditions permit, ventilation equipment can be used to discharge volatile gases in time to reduce the concentration of harmful substances in the air.
Second, pay attention to the use environment. These two are quite sensitive to environmental factors such as temperature and humidity. If the temperature is too high, it may cause the polymer to soften and deform, affecting its performance and use effect; if the humidity is too high, it may cause reactions such as hydrolysis of methylsiloxane, which will change the material characteristics. Therefore, it is necessary to use and store in a suitable temperature and humidity environment according to the product instructions.
Third, strictly follow the ratio and operating specifications. When mixing the two, it must be carried out in strict accordance with the specified ratio. Improper ratio may seriously affect the performance of the final product. During operation, stirring speed, time, etc. are also required. Precise control can ensure that the two are evenly mixed and give full play to the best performance.
Fourth, pay attention to storage conditions. It should be stored in a cool, dry, dark place, away from fire and oxidants. Improper storage may cause product deterioration and performance degradation. At the same time, it is necessary to pay attention to the shelf life of the product. If the expired product has expired or has expired, it should be checked in detail before use.
Fifth, know the compatibility. It is necessary to consider its compatibility with other materials in contact, in some cases, or chemical reactions with other substances, affecting performance or even damaging the material. Before use, a small-scale compatibility test can be carried out.
What are the advantages of Methylsiloxane Polymer compared to other similar products?
Compared with other similar products, the advantages of methylsiloxane and polymer lie in the following points.
The product formed by methylsiloxane and polymer has excellent chemical stability. Just like the ancient city, it is difficult for foreign enemies to invade. The synthetic substances of the two can resist the erosion of many chemicals, such as strong acids and alkalis, and will not be moved. And other similar products, in case of strong acids and alkalis, or like a soil castle in a torrent, instantly disintegrate, and it is difficult to maintain the integrity of their own structure.
Furthermore, its physical properties are also excellent. In terms of flexibility, it is like a soft willow in spring, which can bend at will without breaking, and can adapt to a variety of complex shapes and environments. In contrast, other similar products, such as winter stiff wood, are stiff and easy to fold, and are stretched thin where deformation is required.
And the thermal stability of this substance is quite good, just like real gold that can be tempered by fire. Under high temperature environment, it can still maintain its performance stability, without softening or deformation. In contrast, other similar products, in case of high temperature, are like snow in case of warm sun, quickly melting and deforming, losing their original function.
In addition, its waterproof performance is also an absolute one. Like the water repellent of lotus leaves, water droplets roll down without leaving marks, which can effectively block water penetration. And the waterproof effect of other similar products, or like a sieve containing water, is full of holes, making it difficult to be waterproof.
This methylsiloxane and polymer have significant advantages over other similar products in terms of chemical stability, physical properties, thermal stability and water resistance, and can play a unique role in many fields.
What is the market price range for Methylsiloxane Polymer?
The market price range of methylsiloxanes and polymers is difficult to describe in a single word. The prices of the two are influenced by many factors and are complex.
The first to bear the brunt is quality and purity. High-purity, high-quality methylsiloxanes and polymers have high prices; while those with lower quality and poor purity have low prices. If high-purity products are required in the fine chemical industry, their prices must be higher than those of ordinary industrial grade.
Furthermore, the market supply and demand situation is also critical. If the market has strong demand for methylsiloxanes and polymers and limited supply, the price will rise; conversely, if the supply exceeds demand, the price will fall. If the emerging electronics industry rises, the demand for related high-performance polymers increases sharply, and its prices fluctuate accordingly.
The difference in production processes also affects prices. Advanced and efficient production processes can reduce costs, and product prices may be relatively close to the people; if the production process is complex and expensive, the price will naturally be high.
In addition, the fluctuation of raw material prices also affects the prices of methylsiloxane and polymers. If the price of raw materials is high, the price of finished products will also be high; if the price of raw materials falls, the price of finished products will also have room to decline.
Generally speaking, the price of methylsiloxane per kilogram may range from tens to hundreds of yuan. Ordinary industrial grade methylsiloxane, the price may be around 50-150 yuan per kilogram; while high purity, special purpose, or 200-500 yuan per kilogram, or even higher.
The price difference of polymers is more significant. Common general-purpose polymers, the price per ton may be in the thousands; while high-performance, special polymers, the price per ton can reach tens of thousands of yuan, even hundreds of thousands of yuan. Such as some special polymers used in the aerospace field, the price is high, or over 500,000 yuan per ton.
