PU Application Areas

Alkyl Sulfonic Acid Phenyl Ester M-50 (ASE M-50) is a high‑performance, eco‑friendly plasticizer and adhesion promoter. With excellent gelation ability, strong saponification resistance, and a polar molecular structure, it plays a key role as a functional additive in various polyurethane (PU) applications:

PUR (Polyurethane Sealants & Coatings)

  • Plasticization & Anti‑Aging: Serves as the primary plasticizer in one‑component (1K) and two‑component (2K) PU sealants and waterproof coatings, effectively adjusting hardness and improving flexibility.

  • Saponification & Hydrolysis Resistance: Its chemical structure provides strong resistance to alkaline and humid environments, preventing degradation or chalking when exposed to moisture or cement substrates.

PU Foam (Polyurethane Foams)

  • Equipment Cleaning Agent Component: Offers excellent penetration and dissolving ability, commonly used in cleaning agents for PU foaming machines and pipelines to remove reactive PU residues.

  • Foam Property Adjustment: Functions as an auxiliary additive in rigid or semi‑rigid foam formulations, optimizing cell structure and improving low‑temperature flexibility.

PU Adhesives (Polyurethane Adhesives)

  • Enhanced Initial & Final Bond Strength: The benzene ring and sulfonate polar groups improve substrate wetting, acting as an adhesion promoter, particularly suitable for footwear, composite films, and industrial structural adhesives.

  • Weather & Medium Resistance: Strengthens peel resistance under thermal cycling or humid conditions, preventing adhesion loss caused by plasticizer migration.

TPU (Thermoplastic Polyurethane)

  • Improved Processing Flowability: Plasticization reduces melt viscosity, making extrusion, injection, and calendering easier.

  • Reduced Hardness & Increased Softness: Provides excellent softness and tactile feel while maintaining high tensile strength.

  • Mechanical Balance: With superior polarity matching and compatibility, it minimizes migration issues common with conventional plasticizers, while retaining TPU’s abrasion and tear resistance.

PVC Application Areas

Alkyl Sulfonic Acid Phenyl Ester M-50 (ASE M-50) is a high‑performance, eco‑friendly plasticizer. With excellent gelation ability, saponification resistance, and polar structure, it demonstrates outstanding performance in PVC applications:

PVC Soft & High‑Elastic Products

  • High Polarity & Excellent Compatibility: Exhibits strong polarity and compatibility with PVC resin, even at high dosage levels, without exudation. Designed for ultra‑soft and highly elastic products such as children’s toys and large yoga balls.

  • Low‑Temperature Rapid Gelation: Provides highly efficient gelation at lower temperatures, significantly shortening processing and molding cycles, improving productivity, and reducing energy consumption.

PVC Coating & Plastisol Processing

  • Easy Thickening & Stable Rheology: Delivers excellent thickening and rheological control in PVC paste resin coating processes, ensuring smooth and stable application.

  • Good Surface Printing & Adhesion: With superior compatibility and low migration, finished products maintain excellent surface quality, facilitating subsequent printing, painting, or lamination.

PVC Foamed Products

  • Easy Foaming & Structural Optimization: Works effectively with blowing agents to achieve uniform gas expansion and dispersion, producing fine‑celled, resilient, and density‑balanced foams.

  • Long‑Lasting Softness & Anti‑Migration: Provides strong hydrolysis and oil resistance, maintaining softness and elasticity in highly flexible foams while preventing oil exudation common with conventional plasticizers.

NBR & NBR/PVC Application Areas

Alkyl Sulfonic Acid Phenyl Ester M-50 (ASE M-50) is a high‑performance, eco‑friendly plasticizer. With excellent gelation ability, saponification resistance, and polar structure, it serves as a key functional additive in NBR and NBR/PVC foaming applications:

NBR Rubber & Sealing Components

  • Maintained Vulcanization Characteristics: Exhibits excellent compatibility and chemical stability in rubber compounding and crosslinking systems, without delaying vulcanization speed, ensuring consistent production rhythm and crosslinking efficiency.

  • Saponification & Hydrolysis Resistance: Strong resistance to humid and alkaline environments, preventing degradation or chalking in rubber products under long‑term exposure.

NBR/PVC Foam (Rubber‑Plastic Foams)

  • Efficient Gelation & Processing: With superior gelation ability, it promotes effective plasticization of NBR and PVC blends, optimizing cell structure and improving low‑temperature flexibility.

  • Polarity Matching & Anti‑Migration: Its unique polar structure provides softening and plasticization while minimizing exudation and migration issues, ensuring long‑term mechanical balance and weather resistance in foams.
