Environmentally Safe Non-Toxic Sodium Polyacrylate Ice Pack with Long-Lasting

Product Specification

Product Overview

Environmentally Safe Biodegradable Gel Ice Packs are cooling packs formulated with sodium polyacrylate (CAS No. 9003-04-7) as the core water-absorbing and gel-forming material.
The polymer rapidly absorbs water and converts it into a stable gel, delivering long-lasting, consistent cooling performance. Designed with environmental responsibility in mind, these gel ice packs are suitable for cold chain logistics, food & beverage transport, pharmaceutical shipping, medical use, and personal cooling applications.

FAQ

Q1: What role does sodium polyacrylate play in the gel ice pack?

A: Sodium polyacrylate is the core absorbent polymer. It absorbs water and forms a stable gel that stores cold efficiently and releases it slowly, ensuring long-lasting cooling.

Q2: Is the gel ice pack safe if it leaks?

A: The gel is non-toxic and environmentally safe, but it is not edible. If leakage occurs, clean with water and dispose of according to local waste regulations.

Q3: Can these gel ice packs be reused?

A: Yes. They are designed for multiple freeze-thaw cycles without significant loss of cooling performance or gel integrity.

Q4: Are the gel ice packs biodegradable?

A: The product is formulated with eco-friendly and biodegradable design principles. Actual biodegradation performance may vary depending on disposal conditions and local standards.

Q5: What temperatures can the ice packs reach?

A: When fully frozen, they typically maintain temperatures between 0°C to −18°C, depending on gel formulation, pack size, and freezer conditions.

Q6: Can the gel concentration be customized for longer cooling time?

A: Yes. Gel concentration, pack thickness, and size can all be customized to achieve specific cooling durations and performance targets.

Q7: Is this product suitable for pharmaceutical cold chain transport?

A: Yes. It is widely used for pharmaceutical, vaccine, and biotech cold chain logistics, provided it is used with appropriate secondary packaging and validation.
