I. Category Name

　　Modified Organic Silicone Defoamer XP-S-129

II. Overview

　　The XP‑S‑129 series of silicone defoamers is a class of defoaming agents meticulously formulated by combining polysiloxane with specialized foam‑suppressing and -eliminating ingredients, under the action of our company’s proprietary emulsifiers and dispersants. Its salient features include excellent foam‑suppressing performance, rapid defoaming speed, outstanding stability, non‑toxicity, non‑corrosiveness, and the absence of adverse side effects.

　　The XP‑S‑129 series products are widely used in emulsion polymerization, textile printing and dyeing, oil extraction, cleaning, and other industries. They deliver particularly outstanding defoaming and foam‑suppressing performance in weakly alkaline systems, making them a well‑recognized, high‑quality line of defoamers.

III. Typical Product Data

Ionic emulsion	Nonionic
pH value	7–8.5
Solid content	(10–40%, adjustable according to customer requirements)
Viscosity (20°C, No. 3 rotor, 30 rpm)	500–4000 mPa·s
Emulsion stability	After centrifuging at 3,000 rpm for 20 minutes, the emulsion remains unseparated.

IV. Application Areas

　　1. Suitable for defoaming in textile printing and dyeing processes, as well as for foam suppression and inhibition in textile printing and dyeing auxiliaries.

　　2. Used to eliminate harmful foam in water treatment, industrial circulating water systems, paper pulping and washing, chemical cleaning, fertilizer anti-caking agents, petrochemicals, and other industries; it exhibits excellent defoaming and foam‑suppressing performance in weakly alkaline systems.

　　3. Used in oil extraction to eliminate harmful foam in drilling mud and cement used for well cementing.

　　4. Used to eliminate foam in other aqueous systems.
