Elvanol T-25

In the modern field of fine chemicals, polyvinyl alcohol (PVA), as a versatile water-soluble polymer, is widely used in various industries such as papermaking, textiles, adhesives, and packaging materials. Among the many PVA products, the ELVANOL series, with its unique production process and excellent physicochemical properties, has become a high-performance benchmark in industrial applications.   1. Core Technological Advantages and Physicochemical Characteristics of ELVANOL The primary reason for ELVANOL's high market recognition lies in its unique particle morphology and molecular structure design. This special production process significantly improves efficiency in practical operations.     ♠ Excellent Solubility and Energy-Saving Benefits Traditional polyvinyl alcohol often requires high temperatures and long stirring times during the dissolution process, which not only increases energy consumption but also limits its application in some continuous production lines. A major technological breakthrough of ELVANOL is its ability to dissolve simultaneously in the continuous cooking process of starch. For the papermaking and textile industries, this means that PVA can be directly mixed and processed with starch, eliminating the need for separate dissolution tanks or complex pre-treatment processes. From a physical perspective, this improved water solubility directly translates into reduced production costs. The significantly shortened dissolution time improves the turnover rate of production equipment and significantly reduces the thermal energy consumption during the heating process. For large manufacturing enterprises pursuing ultimate cost control, this characteristic of ELVANOL has extremely high economic value. ♠ Precise Viscosity and Degree of Hydrolysis Control The ELVANOL series offers a variety of grades to meet different process requirements. For example, the Elvanol 71-30 grade has a viscosity range of 28.5-32.5 cP in a 4 wt% aqueous solution, while the Elvanol 90-50 grade is controlled at 12.0-15.0 cP. All mainstream grades (such as Elvanol 71-30 and Elvanol 80-18) have a degree of hydrolysis of 99.5%. This high degree of hydrolysis means that the molecular chain contains a very high proportion of hydroxyl groups, ensuring its excellent film-forming properties and extremely high adhesive strength. Meanwhile, its pH value remains stable between 5.0 and 7.0, exhibiting weak acidity to neutrality, and it possesses excellent chemical stability with most inorganic fillers and substrates. ♠ Synergistic Reinforcement Effect with Inorganic Materials In compression molding or composite material manufacturing, ELVANOL demonstrates excellent mixing uniformity. It can form stable reinforced mixtures with fine powdered inorganic fillers. During the molding process, this uniformity prevents localized stress concentration, improving the structural integrity and surface finish of the final product.   2. Key Application Areas: From Paper Coating to Textile Warp Sizing ELVANOL's application range covers multiple fields, from high-end adhesives to precision photosensitive coatings, with particularly outstanding performance in the paper and textile industries. ♣ Performance Multiplier in the Paper Industry In paper coating applications, ELVANOL is typically used as a co-binder mixed with starch. Due to its excellent barrier properties, it effectively improves the paper's resistance to oil, grease, and oxygen. More importantly, ELVANOL's solubility in continuous cooking processes allows paper mills to simplify the coating preparation process. Through synergistic interaction with starch, it significantly enhances the surface strength of the paper, reducing dusting and linting during the printing process, making it particularly suitable for the production of high-end art paper and packaging cardboard. The T-Series Revolution in the Textile Industry: The Preferred Choice for Polyester/Cotton Blends For the textile industry, ELVANOL has specially developed the T-series (such as Elvanol T-25) of unique copolymers. This series is designed specifically for polyester/cotton blends and other warp sizing applications. A major challenge in textile processing is "desizing." Traditional sizing agents often require large amounts of chemical reagents during the desizing process, and the results are often unsatisfactory. The unique feature of the ELVANOL T-series is its stronger water solubility under alkaline conditions. In the finishing stage, the fabric only needs to be treated in a standard alkaline bath to achieve rapid and thorough desizing. This not only improves the dyeing uniformity of the fabric but also reduces chemical damage to the fibers. Diverse Industrial Applications Besides its two main pillar industries, ELVANOL also plays an irreplaceable role in the following areas: Adhesives:  With its high bonding strength and film-forming properties, it is used for bonding wood, paper, and porous materials. Ceramic Industry: As a green body binder, it improves the strength of molded green bodies. Photosensitive Coatings: Utilizing its high purity and low ash content (Na2O less than 0.35%-0.5%), it is used in precision electronic chemicals. Molding: Provides a more uniform molding effect, suitable for the manufacture of complex-shaped parts.   3. Environmental Attributes and Sustainable Development of Future Industries Under today's stringent global environmental regulations and carbon neutrality goals, the environmental attributes of materials have become a core criterion for corporate procurement. ELVANOL was designed with environmental compatibility in mind from the outset. ♥ Biodegradable and Environmentally Harmless ELVANOL is a polymer that poses no health hazards. In specific industrial wastewater treatment environments, it can be decomposed by microorganisms into carbon dioxide and water, greatly reducing the pressure on wastewater treatment systems. Compared to many synthetic plastic slurries, its biodegradability makes it a preferred material for green textiles and environmentally friendly packaging. ♥ Resource Recycling and Circular Economy In the textile industry, the recycling of sizing agents is an important means of reducing costs and pollution. ELVANOL copolymers exhibit strong performance stability during recycling, and their film-forming and bonding properties do not significantly degrade even after multiple cycles. This makes it one of the most economical textile sizing agents on the market that meets environmental requirements. ♥ Indirect Environmental Benefits from Low Ash Content and High Purity The volatile content of ELVANOL is consistently controlled below 5.0%. This high solid content and low impurity (low ash content) characteristic means that very few harmful gases and residual inorganic salts are released during the processing and heat treatment of the final product. This not only protects the precision of production equipment but also reduces the burden of exhaust gas treatment. ♥ Compliant with Sustainable Development Strategies As consumer demand for sustainable products grows, companies using ELVANOL as a raw material can more easily obtain relevant environmental certifications. Whether in reducing production energy consumption or in the end-of-life treatment of products, ELVANOL demonstrates a forward-thinking industrial mindset: achieving a win-win situation between production efficiency and ecological balance through technological innovation.   The ELVANOL series of polyvinyl alcohol is not only a chemical raw material but also a mature industrial solution. Through special molecular design, it solves technical challenges such as dissolution efficiency, application strength, and alkaline desizing, while its biodegradable and recyclable properties address the contemporary demand for environmental protection.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com
