Can the amino silicone oil produced by Qiangli Chemical be applied to soft masterbatch?

It is applicable, but it is necessary to select the correct model, control the amine value and processing temperature, and emulsify first before pelletizing.

1. Product Adaptability (Amino Silicone Oil of Qiangli Chemical)

Structure: Aminoethylaminopropyl polydimethylsiloxane, low cyclic body (D4/D5＜3000ppm), low volatility, good thermal stability and low migration tendency.

Amine value range: 0.21–0.9 mmol/g (nitrogen content 0.21%–0.9%), adjustable according to masterbatch style.

Viscosity: 700–15000 mPa·s, compatible with different fibers and processing equipment.

Recommended typical models:

QL-2211: Amine value 0.21, viscosity 3000–5000 cP, low yellowing and smooth softness, suitable for light-colored/thin fabric masterbatch.
QL-2212: Amine value 0.24, viscosity 6000–8000 cP, fluffy and soft, suitable for cotton/cotton-polyester masterbatch.
QL-2214: Amine value 0.9, viscosity 700–1500 cP, high bulkiness and wash resistance, suitable for dark-colored/heavy fabric masterbatch.

2. Key Application Points for Soft Masterbatch

Amine Value Selection (Critical)

Light color/bleached fabric: 0.2–0.4 mmol/g (e.g. QL-2211), add 0.1% BHT for anti-yellowing.
Medium color/general use: 0.4–0.6 mmol/g (e.g. QL-2212), balance softness and yellowing resistance.
Dark color/heavy fabric: 0.6–0.9 mmol/g (e.g. QL-2214), high bulkiness and wash resistance.

Processing Requirements

Emulsification is mandatory: Prepare stable microemulsion of 30%–50% concentration first (nonionic/weak cationic system); avoid mixing with anionic auxiliaries.
Temperature control: Extrusion/pelletizing temperature ≤ 160℃ (amino group tends to oxidize and turn yellow above 180℃).
Dosage: 5%–15% in masterbatch (calculated by effective silicone content); excessive dosage easily causes migration and affects dyeing.
Carrier resin: Adopt LDPE/PP/polyester elastomer with good compatibility with silicone oil and low precipitation.

Performance Advantages

Hand feel: Smooth softness, bulkiness, antistatic property, wash resistance ≥ 20 times.

Stability: Low cyclic body and low volatility; no obvious migration after 6 months of masterbatch storage.

Compatibility: Can be compounded with stearic acid, PEG, fatty alcohol, etc., to adjust hand feel style.

3. Common Problems and Countermeasures

Yellowing: Reduce amine value to ≤0.4, add antioxidant, control temperature ≤160℃.
Migration/Precipitation: Adopt low viscosity (＜5000 cP) and low cyclic body model; dosage ≤15%.
Emulsion instability: Use nonionic emulsifier, adjust pH to 5.5–6.5, adopt high-speed homogenization.

4. Conclusion & Suggestion

The amino silicone oil of Qiangli Chemical is fully applicable to soft masterbatch. Priority is given to QL-2211/2212 (medium-low amine value, low yellowing). Follow the process of emulsification → low-temperature pelletizing → dosage control to stably produce soft, smooth and wash-resistant soft masterbatch.
