In the field of plastic processing, polycarbonate is widely used for its transparency and rigidity. However, issues like "brittleness" and "susceptibility to high-temperature aging" have long plagued the industry. Now, a material called terminal phenolic modified silicone oil (coded IOTA 28723/28724/28725/28729) has become the "golden partner" for polycarbonate, easily solving these pain points.
In terms of appearance, it is a transparent oily substance ranging from colorless to light reddish-brown, with a uniform and bright texture and no impurity precipitation. Whether it is subsequently mixed with other materials or used alone, it can maintain a stable state. In terms of key properties, its "data performance" is quite impressive: at 25°C, the density ranges from 0.970 to 0.990 g/cm³, which is similar to the density of water, facilitating the calculation of dosage and mixing ratio; the refractive index is maintained at 1.406 to 1.430, which can well meet the processing needs of transparent materials without affecting the light transmittance of the finished product; the viscosity varies according to different codes, ranging from 60 mm²/s to 230 mm²/s. Whether it is a scenario requiring high fluidity or a process requiring a slightly thicker texture, a suitable model can be found. More importantly, its volatile content is ≤1.0%, meaning that almost no impurities will be generated due to high-temperature volatilization during processing. The chromaticity is also controlled at ≤100 Pt-Co (some models ≤50 Pt-Co), which can maximize the appearance purity of the finished product.
Its core advantage lies in the special structure of "phenolic end-capping". The phenolic group is like a "powerful assistant" of the material: it not only has high reaction activity and can easily "combine" with resins such as polycarbonate but also has excellent heat resistance and anti-aging ability. When used for polycarbonate modification, it can make the originally brittle material more flexible and significantly improve impact resistance—for example, electronic casings made of modified polycarbonate are less likely to break when dropped. At the same time, the heat resistance of the material will also be enhanced, so it is not easy to deform or turn yellow when used in high-temperature environments. The anti-aging and flame-retardant properties can also be improved simultaneously, extending the service life of the product and enhancing its safety in use.
In addition to "focusing on" polycarbonate, it can also play an important role in other fields. For example, it can be mixed or copolymerized with resins such as polyester and polyurethane to help optimize the properties of these materials; it can even be directly used to prepare lubricating oils to make machinery operate more smoothly; when used as a release agent, it can help plastic and resin finished products easily separate from molds without affecting the surface texture of the finished products.
In terms of packaging and storage, it is also thoughtfully designed: there are three specifications—20KG (25L barrel), 200KG (200L barrel), and 1000KG (1000L plastic barrel), which can meet both small-batch trials and large-scale production needs; when sealed and stored at room temperature, its validity period can reach 24 months. For enterprises that need to improve material performance, this terminal phenolic modified silicone oil is undoubtedly a cost-effective choice.
