FAQ
Q1: What is the difference between polyester and polyether PU?
Polyether PU: Engineered with exceptional resistance to hydrolysis, continuous moisture, and microbial attack. It maintains high flexibility in cold environments and is the industry standard for water lines, pneumatic plumbing in high-humidity zones, and outdoor applications.
Polyester PU: Provides high mechanical tensile strength and superior resistance to dry abrasion, but the chemical bonds will degrade and become brittle when exposed to long-term moisture, humidity, or water contact.
Q2: Does polyether absorb water?
No, polyether PU has excellent water resistance and low moisture absorption. Unlike polyester, its chemical bonds do not break down when in prolonged contact with water or high humidity, preventing premature degradation and maintaining long-term stability in wet pneumatic or fluid systems.
Q3: How to distinguish between polyester and polyether PU Hoses?
Q4: How to cut a spiral tube properly to meet technical requirements?
We supply spiral tubes strictly tailored to your engineering drawings, ensuring proper spring tension by configuring customized straight tail lengths (E/F lengths) directly at our factory. To avoid manual installation errors on-site, we offer precise factory pre-cutting and end-trimming according to your exact assembly blueprints, ensuring a completely clean, square-cut edge for guaranteed leak-free connections.
