Imaliner® Bi-Layer Pharmaceutical Grade Thermoplastic Elastomer (TPE) tubing is specially designed with peristaltic pump compatibility in mind. With excellent flex crack resistance, Imaliner® has a low coefficient of friction with a smooth bore to ensure less contamination and to enhance smooth fluid flow operation. The outer layer is made from abrasion resistant, FDA compliant TPE to reduce spallation, while the inner layer is highly resistant to alcohol-based solvents and various preservatives (M-Cresol, Parabens, Benzyl Alcohol, BKC).
