TPV Hose (Thermoplastic Vulcanizate Hose) is a flexible tubing primarily made from thermoplastic vulcanized rubber (TPV), offering exceptional weather resistance, elasticity, and chemical corrosion resistance. Below is a comprehensive overview of its key characteristics and application fields:

一、Material Properties

1. ‌Thermal Resistance‌
   Operating temperature range: -60°C to 150°C, with specific models capable of long-term use in 150°C environments.

2. ‌Chemical Resistance‌
   Excellent resistance to oils, acids/alkalis (including seawater), and ozone. Volume expansion rate after 72-hour immersion in 100°C engine oil is only 8%.

3. ‌Mechanical Performance‌
   Compression set <20%, rapid elastic recovery, and hardness range spanning Shore A 20-904.

4. ‌Environmental Safety‌
   Free of heavy metals and halogens, compliant with RoHS and REACH certifications
   .

二、Structural Types

1. ‌Pure TPV Hose‌
   Used in food-grade transportation and medical devices, e.g., anti-slip handle sleeves with 25mm inner diameter and 3mm wall thickness.

2. ‌Reinforced TPV Hose‌

• ‌Spring Steel Reinforcement‌: Enhances compressive and tensile strength, suitable for automotive exhaust pipes and industrial ventilation systems.

• ‌Braided Mesh Reinforcement‌: Withstands high pressure up to 3 kg/cm², e.g., high-temperature steam delivery pipes
