Synoflex ASE (Phenyl Alkyl Sulfonate) is a versatile, non-phthalate plasticizer renowned for its excellent plasticizing efficiency and outstanding environmental profile. It serves as a direct, high-performance, and cost-effective alternative to conventional phthalate plasticizers like DOP/DEHP and other branded alternatives such as Mesamoll. It is specifically designed for a wide range of polymers, including PVC, PU, and various rubbers, delivering enhanced processing and end-product performance.
Excellent Plasticizing Performance: Offers plasticizing efficiency comparable to DOP. Formulations using DOP can be directly replaced with Synoflex ASE without altering existing recipes or processing parameters.
Superior Hydrolysis Resistance: Its unique chemical structure provides exceptional resistance to water and alkali metals, making it far superior to DOP in applications requiring contact with moisture or soaps.
Broad Material Compatibility: Exhibits excellent compatibility with a wide range of polymers, including PVC, PU, Natural Rubber (NR), Styrene-Butadiene Rubber (SBR), Nitrile Rubber (NBR), and Chloroprene Rubber (CR).
Enhanced Weatherability & UV Resistance: Provides significant low-temperature stability and resistance to ultraviolet light, ensuring long-term durability and performance in outdoor applications.
High Electrical Insulation: Possesses excellent volume resistivity (≥ 2.7×10¹⁴ Ω/cm²), making it ideal for cable and wire applications.
Eco-Friendly & Safe: Certified by SGS to be free of phthalates (6P & 17P), alkylphenols (NP), and polycyclic aromatic hydrocarbons (PAHs). It is a non-toxic solution for sensitive applications.
Low Volatility & High Flash Point: With a flash point ≥200°C and low volatility, it reduces processing fumes and weight loss during heating, improving workplace safety and product stability.
Excellent Gelling & Processing Aid: Promotes excellent gelation, lowers processing temperatures, and shortens production cycles.
Synoflex ASE is a universal plasticizer suitable for numerous industries and polymer systems:
Polyvinyl Chloride (PVC):
Films: Agricultural films, swimming pool liners, bath curtains, welded membranes, electrical insulation films.
Extrudates: Profiles, tubes, hoses, and automotive parts.
Moldings: Footwear (soles, sandals), work shoes, toys, industrial products, floor mats.
Coatings: Synthetic leather, inflatable products, tarpaulin coatings.
Polyurethane (PU):
Used in single and dual-component sealing and adhesive systems.
Machine Cleaning: Effectively used as a cleaning agent for PU processing equipment due to its non-reactive nature with isocyanates.
Rubber Compounds:
Effective plasticizer for NR, SBR, NBR, and CR in various technical goods.
Synoflex ASE is hygroscopic (moisture-absorbing). It must be stored in a sealed, dry environment and protected from contact with iron to prevent discoloration. The recommended shelf life is two years.
Synoflex ASE stands out as a robust, economical, and environmentally sound choice for formulators seeking to replace traditional phthalates. Its combination of superior technical properties—especially its hydrolysis resistance, weatherability, and broad compatibility—makes it an ideal drop-in solution for enhancing product quality across PVC, PU, and rubber applications while meeting modern safety and regulatory standards.
