Hebei Tangzhi Technology Co., Ltd.
Elevating global manufacturing standards with high-substituted hydroxypropyl cellulose, delivering unparalleled thermoplasticity and stability for pharmaceutical and industrial applications.
In the realm of advanced polymer science, cellulose is fundamentally transformed into High-Substituted Hydroxypropyl Cellulose (H-HPC) through a precise etherification process. This modification grants the material exceptional water solubility and chemical inertness, making it a cornerstone in pharmaceutical binder technology and high-end cosmetic stabilizers.
Our proprietary production ensures that cellulose is processed under rigorous high-pressure conditions to achieve a uniform substituent distribution. This technological advantage results in superior thermoplasticity (130-150°C) and an ultra-low ash content, ensuring that the final film-forming properties provide unmatched gloss and elasticity for professional industrial coatings.
Our H-HPC is developed through three primary technical dimensions to ensure pharmaceutical-grade purity and industrial-strength performance.
Ensuring molecular precision through advanced alkalization and etherification protocols.
Dynamic re-gelation and dissolution capabilities for adaptive formulations.
Optimized for seamless integration in organic solvents and aqueous solutions.
Quantitative analysis of substance composition and comparative performance across different H-HPC grades.
Detailed technical parameters for high-substituted hydroxypropyl cellulose based on diverse application requirements.

Expert answers to common technical and commercial inquiries.
Essentially, cellulose is modified by introducing hydroxypropyl groups into its molecular chain, creating a non-ionic polymer with excellent solubility and thermal properties.
Since cellulose is structured to be resistant to rapid clumping, we recommend adding H-HPC slowly to vigorously stirred water or using a hot-water (60°C) pre-dissolution method.
Yes, because cellulose is etherified in our process, H-HPC dissolves easily in acetone, ethanol, chloroform, and glacial acetic acid.
Unlike standard derivatives, when cellulose is highly substituted, it can be melted at 130-150°C while remaining water-soluble after cooling.
No. Because the raw cellulose is chemically inert, H-HPC is non-toxic, harmless to physiology, and does not react with other drug components.
Since the refined cellulose is hygroscopic, H-HPC must be kept in sealed containers, away from sunlight, moisture, and strong acids/alkalis.
Partner with the leaders in the Chemical Raw Materials and Specialty Products industry to integrate high-performance cellulose is derived H-HPC into your next innovation.
