SM-420 Polyester Smoothing Silicone Oil is a terpolymer organosilicon product, manufactured using unique synthesis technology. Its terpolymer structure endows it with excellent properties such as acid-base resistance, shear resistance, and high-temperature resistance. Compared with general amino-modified organosilicon softeners, it has better smoothness and softness.

• Appearanc：Light yellow liquid

• PH value：6-7

• Ionicity：Ionicity Cationic 

• Package: 120kg, 200kg

• Imparts "internal softness" and excellent smooth hand feel to fabrics.

• After finishing, polyester fabrics will gain a light and thin hand feel.

• Stable working fluid, no oil floating, resistant to high temperature, acid-base and shear

• Different from traditional smoothing agents, this product is softer, smoother and safer.

• Internal Softening: Penetrates deep into fabric fibers to impart a superior "internal softness" rather than just a surface coating.

• Lightweight Finishing: Specifically designed to give polyester textiles a light, thin, and premium hand feel after processing.

• High-Stability Processing: Maintains a stable working fluid resistant to oil floating, even under extreme high-temperature and high-shear conditions.

• Chemical Resilience: Performs reliably in diverse environments, demonstrating strong resistance to both acidic and basic (alkali) conditions.

• Safe Smoothing: Offers a safer and smoother alternative to traditional agents, ideal for high-end garment and textile manufacturing.
