Product Description

P-105 is a high-performance, high-molecular-weight non-ionic block copolymer widely recognized for its multi-functional efficacy in advanced chemical formulations. Featuring a perfectly engineered HLB value of 15 and a high cloud point of ~90°C, this 100% active copolymer exhibits exceptional water solubility and elite thermal stability. It functions as an indispensable high-tier emulsifier, solubilizer, and steric stabilizer for complex aqueous systems, guaranteeing prolonged shelf life and structural integrity even under high-temperature stress environments.

Key Applications & Technical Benefits

• Pharmaceutical & Personal Care Excipient: Highly optimized for solubilizing hydrophobic active ingredients (APIs) and essential oils. It provides superior stability and texturizing control in premium creams, lotions, and targeted drug delivery matrices.

• High-Temperature Industrial Emulsification: Benefiting from its ~90°C cloud point, it maintains its surface-active and structural properties under severe thermal conditions, making it perfect for industrial emulsion polymerization, textile processing, and heated cleaning systems.

• Advanced Pigment & Powder Dispersion: Highly efficient at wetting and dispersing fine solid particles or pigments in water-based media. Its long polymer chains provide powerful steric hindrance, preventing particle agglomeration and flocculation over extended storage periods.

• Polymeric Film-Forming & Surface Protection: The high molecular weight (~6500) structure provides excellent temporary film-forming characteristics, acting as a functional barrier coating, lubricating layer, or anti-static modifier on various substrates.
