In the vast world of chemical materials, Methylphenyl Cyclosiloxane IOTAR21 is gradually emerging as a focal point, attracting attention from numerous industries with its unique properties. It has a CAS No. of 68037 - 54 - 7, and also contains components with CAS numbers 546 - 45 - 2, 77 - 63 - 4, and 34239 - 75 - 3. These components work in synergy to endow it with excellent comprehensive performance.

Purity and Morphology: A Direct Reflection of Quality

The active substance content of IOTA R21 is quite impressive, with two specifications available: greater than 99.0% and 99.85% (polymer - grade). High purity means that it can better exert its own properties during use, reducing the impact of impurities on product quality. In terms of morphology, it appears as a colorless liquid at 25℃. This clear and transparent appearance is not only aesthetically pleasing but also holds great advantages in fields where product appearance is important, such as cosmetics and coatings.

Physical Properties: Adapting to Diverse Needs

Its boiling point ranges from 160 - 260℃ under a pressure of 0.13kPa. This wide boiling - point range allows it to maintain relatively stable performance under different processing temperatures. With a density of 1.125g/cm³ at 25℃, this moderate density helps it disperse evenly when mixed with other substances, ensuring the quality stability of the products. A flash point greater than 160℃ (closed - cup) indicates good safety during storage and use, reducing the risk of fire hazards. The refractive index of 1.545 at 25℃ gives it potential application value in the optical field, enabling it to be used in the manufacture of products with high optical performance requirements.

Chemical Properties: Pure and Impurity - Free

In terms of chemical properties, the halogen content of IOTA R21 is less than 5ppm. Low halogen content enables it to meet the quality requirements in fields with strict chemical composition restrictions, such as the electronics industry. Moreover, it is free from PCBs (polychlorinated biphenyls) and PAHs (polycyclic aromatic hydrocarbons), which are generally considered harmful substances. This characteristic further enhances its safety and applicability.

Application Prospects: Vast and Boundless

With these outstanding properties, Methylphenyl Cyclosiloxane IOTA R21 has broad application prospects in multiple fields, including cosmetics, coatings, electronics, and optics. In cosmetics, it can serve as a softening agent to improve the texture and skin - feel of products. In the coating industry, it can enhance the adhesion and gloss of coatings. In the electronics industry, it can be used to manufacture encapsulation materials for electronic components. In the optical field, it has the potential to be used in the manufacture of optical lenses. As technology continues to advance, its application areas are expected to expand further.
