In the material processing industry, an additive with multiple properties can greatly improve production efficiency and product quality. Terminal phenolic group-modified silicone oil (IOTA 28723/28724/28725/28729) is precisely such a product, suitable for both resin modification and additive preparation.
In terms of appearance and basic performance, the product is a colorless to light reddish-brown transparent oily substance with a clear texture. It can be evenly dispersed during mixing without affecting the appearance of finished products. The key parameters show stable performance: at 25℃, the density is 0.970-0.990g/cm³, which is close to the density of water, making it convenient for enterprises to calculate the dosage; the refractive index is 1.406-1.430, which is suitable for the processing of transparent resins and avoids damage to the light transmittance of finished products. The viscosity is divided into four grades: IOTA 28723 (60-120mm²/s), IOTA 28724 (70-130mm²/s), IOTA 28725 (100-160mm²/s), and IOTA 28729 (190-230mm²/s), which can be flexibly selected according to different process requirements. At the same time, the product has a volatile content of ≤1.0%, which is not easy to volatilize and lose at high temperatures, ensuring processing stability; the chromaticity is strictly controlled, with most models ≤50Pt-Co, reducing the problem of off-color in finished products.
The core advantage of the product lies in its "phenolic group-terminated" design. Phenolic groups have high reactivity and can efficiently copolymerize or blend with resins such as polycarbonate, polyester, and polyurethane to achieve modification easily. Additionally, phenolic groups have strong heat resistance and anti-aging capabilities. After modification, the flexibility and impact resistance of resins are significantly improved; for example, modified polycarbonate products have greatly enhanced anti-drop performance. They can also improve the heat resistance, anti-aging properties, and flame retardancy of resins, extending the service life of products and enhancing their safety in use.
It has a wide variety of application scenarios. In the field of resin processing, it is mainly used for polycarbonate modification to address its performance shortcomings, and can also be used to optimize the performance of other resins such as polyester and polyurethane. In the field of additives, it can be used to prepare lubricating oils to reduce mechanical wear and extend equipment service life, and can also be used as a release agent to enable rapid demolding of plastic and resin finished products while maintaining a smooth surface.
In terms of packaging and storage, the product offers three specifications: 20KG, 200KG, and 1000KG, adapting to different production scales. It can be stored in a sealed state at room temperature with a 24-month validity period, facilitating long-term storage by enterprises and ensuring production continuity. For enterprises that need to improve resin performance or optimize additive effects, this terminal phenolic group-modified silicone oil is a highly cost-effective choice.
