由 faqiuqi@gmail.com At its core, IUMRS Sodium Polyacrylate (CAS 9003-04-7) is a synthetic polymer derived from acrylic acid. Its magic lies in its molecular structure—a network of long chains containing sodium carboxylate groups. Upon contact with water, these groups ionize, creating a strong osmotic pressure that drives water into the polymer matrix. The cross-links between the chains prevent dissolution, allowing the polymer to swell into a robust, stable hydrogel that can hold hundreds of times its own weight in water, firmly locked within its structure.
Key Distinction: IUMRS Grade 220 is characterized by its high absorbency rate, exceptional gel strength, and remarkable stability, setting it apart from conventional SAPs.
Unmatched Performance Metrics: The Specifications of Superiority
Sourced from premier production facilities, IUMRS SAP Grade 220 delivers a consistent, high-quality performance profile that meets the most stringent demands:
- Astounding Absorption Capacity: With an absorption ratio exceeding 450 times its own weight in pure water, a minimal amount of resin delivers maximum effect, optimizing material usage and cost-efficiency.
- Rapid Kinetic Action: It achieves near-total saturation within just 3 minutes, enabling quick preparation and activation—a critical factor in time-sensitive logistics and manufacturing processes.
- Superior Gel Strength & Anti-Rewetting: The formed hydrogel possesses high integrity, applying strong suction force (negative pressure) to牢牢锁住水分. This results in minimal to zero free water release under pressure, preventing messy leakage and “rewetting” in hygiene products or soggy meltwater in cold packs.
- Exceptional Thermal Retention: When used in cold chain冰袋, the fully hydrated gel provides prolonged, stable cooling for up to 40 hours, far outperforming the rapid temperature spikes of plain ice or weak gels. The gel can be repeatedly frozen and thawed without significant degradation of its water-holding capacity or structure.
- Controlled Expansion Profile: It exhibits a consistent and manageable swelling height of approximately 17mm under load, ensuring predictable behavior in confined spaces within pads, bags, or composites.
- Enhanced Environmental Stability: Rigorous testing shows superior resistance to environmental degradation. Under natural light exposure for one month, its photo-degradation is a mere 1.12%, significantly lower than the industry average of 2.34%-3.48%, ensuring product longevity during storage and use.
Application Spotlight: Revolutionizing Cold Chain Logistics
The most transformative application of IUMRS Grade 220 is in the next generation of cold chain ice packs and panels.
The Traditional Ice Pack vs. The IUMRS-Powered Ice Pack:
- Traditional: Heavy water weight, risk of rupture and leakage, uneven cooling, short effective duration.
- IUMRS-Enhanced: Lightweight dry powder that transforms upon activation. It locks water into a solid gel matrix that does not leak, even if the outer bag is punctured. The gel provides stable, longer-lasting phase-change cooling (40+ hours), is lighter to ship pre-activated, and conforms perfectly to product shapes. This translates to:
- Reduced Shipping Costs: Lower weight pre-activation.
- Enhanced Product Safety: Zero leakage eliminates water damage risk.
- Guaranteed Integrity: Maintains consistent temperature for longer durations.
- Sustainability: Can be reused multiple times and is ultimately disposable as a non-toxic gel.
Implementation: Manufacturers simply fill durable plastic pouches with a precise dose of IUMRS SAP powder (Grade 220). End-users activate the pack by submerging it in water for a few minutes. The pack swells into a firm, cool, and leak-proof gel brick ready for use.
A Multifaceted Material: Applications Across Industries
The utility of IUMRS Sodium Polyacrylate extends far beyond the cold chain, serving as a critical component in diverse sectors:
- Hygiene & Personal Care: The cornerstone of modern disposable diapers, adult incontinence pads, and feminine hygiene products. Its high absorption rate, superb anti-rewetting capability, and slim profile ensure dryness, comfort, and skin health.
- Agricultural & Horticultural Applications: Used as a soil amendment to improve water retention in arid regions, reduce irrigation frequency, and promote plant growth. Its stability helps conserve water resources.
- Industrial & Specialty Absorbents: For spill containment socks, flood barrier bags, and absorbent mats in workshops, laboratories, and for emergency flood control. It quickly immobilizes large volumes of water-based fluids.
- Food Packaging: Used in tray pads for meat, poultry, and seafood packaging to absorb excess fluids (exudate), extending shelf life and improving product presentation.
- Other Innovative Uses: From water retention in artificial snow and novelty toys to controlled-release mediums for fertilizers or fragrances.
