In modern biomedical and pharmaceutical research, the performance of laboratory animal housing equipment directly impacts experimental accuracy and animal welfare. As one of the most essential components, rat cages must meet multiple performance standards such as high-temperature sterilization resistance, long-term durability, and non-toxicity. Traditional materials like polycarbonate (PC) show limitations under repeated sterilization and chemical exposure. This has led to a growing trend of using PSU (Polysulfone) material for building more reliable and sustainable rat cage solutions.
PSU (Polysulfone) is a high-performance engineering thermoplastic widely used in the medical, food, and laboratory sectors due to its outstanding thermal, mechanical, and chemical resistance properties, making it especially suitable for rat cages.
PSU can withstand temperatures up to 160°C, making it highly suitable for repeated autoclave sterilization.
Maintains shape and strength even after prolonged exposure to 121°C steam for 60+ minutes.
PSU resists a wide range of disinfectants such as alcohols, sodium hypochlorite, and quaternary ammonium compounds.
Retains structural integrity and transparency over time without yellowing, cracking, or degradation.
Compared to PC or PP, PSU is more durable and less prone to breakage, making it ideal for frequent handling and transport.
Strong resistance to mechanical shock reduces risk of damage during cleaning or movement.
PSU offers natural optical clarity, allowing clear and uninterrupted observation of animal activity and health status.
Enables researchers to perform checks without opening the cage, improving workflow efficiency.
Non-toxic and odorless, PSU meets ISO 10993 standards for medical-grade materials and is safe for prolonged animal contact.
Reusable and easy to clean, reducing long-term operational costs and aligning with eco-friendly lab practices.
Rat cages made with PSU offer a comprehensive solution that balances performance and sustainability, resulting in:
Extended service life — 2-3 times longer lifespan than traditional cages.
Improved experimental consistency — no chemical leaching or material breakdown.
Lower resource waste — supports sterilization, reuse, and long-term use.
Better animal welfare — clean, safe, and stable housing conditions.
PSU material is transforming the way laboratory rat cages are designed and manufactured. It delivers superior strength, sterilization compatibility, and environmental responsibility—making it the ideal choice for research institutions and laboratories that demand high-quality, sustainable animal housing equipment.
