Q: Polyether vs Polyester Polyurethane Products • A: Polyether based material has following characteristics: • 1. Fungus Resistance • 2. Low temperature flexibility • 3. Outstanding hydrolytic stability • 4. Resistance to weak Acids/Bases • 5. Recommended for applications undergoing medium to high stress • 6. Burst Pressure Resistance: About the same as Ester based tubing • 7. Polyether-based polyurethanes remain stable in water as warm as 50℃ (122℉) for long periods. Not recommended for running water over 70℃ (158℉). Water absorption is a very low 0.3% to 1% by weight, and volume swell is negligible. • 8. Demonstrate better durability than Ester material based products (around 5 years, versus the 3 years shelf life of Polyester based products, i.e. tubing) • 9. Generally more expensive than Polyester based material • 10. Moisture resistance for pneumatic application • Polyester based material has following characteristics: • 1. Outstanding Oil resistance • 2. Excellent Abrasion resistance • 3. Burst Pressure Resistance: About the same as Ether based tubing • 4. Polyester-based polyurethane tubing is generally stronger and enjoys cost advantage over Polyether based PU tubing. • 5. Not recommended for use in high humidity or exposure to water, as volume swell and reduction of properties may result • To learn more, visit: https://www.taiwanpu.com/en/about/Pol... • Taiwan PU Corporation • 3F-1, No. 9, Wu-Chuan 1st Road, • Sinjhuang District, New Taipei City, • Taiwan R.O.C. • (Postal Code: 24892) • Tel: 886-2-22991666 • Fax: 886-2-22991888 • E-mail: [email protected] • Website: www.taiwanpu.com • Skype: taiwan.pu • Whatsapp: +886-909-012-055 • Line ID: tpuco Wechat • ID: taiwan_pu QQ: 1648735894 • **To persist in providing of excellent quality is the first priority of TPUCO for customers' trust and satisfaction. • • #Polyether, #Polyester, #Polyurethane, #PU
