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.
