PU Tubing Hose

Our company has a history of nearly 20 years since its establishment, and has been committed to the research and development, production, and sales of polyurethane products. We have been committed to the production of PU Tubing Hose for nearly 10 years. We have multiple advanced extrusion production and testing equipment. After years of development, we have a strong production team, technical team, and sales team. The produced pu hose has received unanimous praise from customers for its high-quality products and reasonable prices.

During the storage process, PU Tubing Hose need to pay attention to the following key points to ensure that their performance and lifespan are not affected:
1) Avoid light and UV rays
Store in a cool and dry room, away from direct sunlight (UV rays can accelerate the aging, brittleness, and cracking of PU materials).
→ It is recommended to use opaque packaging or blackout cloth to cover.
2) Temperature and humidity control
Ideal temperature: 10 ° C-25 ° C (avoid high temperatures>40 ° C or low temperatures<-10 ° C).
Humidity: Keep the environment dry (relative humidity ≤ 65%) to prevent mold growth and hydrolysis reactions.
3) Avoid mechanical compression deformation
→ Suspension prohibited: Do not use hooks to suspend hoses (which can cause permanent deformation).
Flat or roll storage:
4) Stay away from chemicals and ozone sources
Keep away from organic solvents (such as acetone and gasoline), strong acids and bases, and ozone generators (such as motors and high-voltage equipment), which can cause PU swelling or cracking.
5) Ventilation and dust prevention
Maintain ventilation in the warehouse to avoid dust accumulation (especially for food/medical grade hoses that need to be sealed and packaged).
6) Do not come into contact with sharp objects
Remove burrs and sharp edges from the storage area to prevent scratching of the pipe wall.
2. Long term storage recommendations
1) Regular inspection: Conduct random checks on the condition of the hose every 3 months (for hardening, deformation, and mold spots).
2) First in, first out (FIFO): Priority is given to using products from earlier batches.
3) Packaging integrity: Ensure that the original packaging is intact and reseal if damaged.
3. Consequences of storing PU Tubing Hose incorrectly
1) Direct sunlight: surface cracking, increased hardness, loss of elasticity
2) High temperature environment: softening deformation, adhesion
3) Wet environment: hydrolysis degradation, decreased strength
4) Squeezing/hanging storage: permanent deformation, internal cavity blockage
5) Exposure to chemicals: swelling, rupture, contamination risk
Following the above specifications can significantly extend the lifespan of PU hoses (usually stored unopened for 2-3 years), ensuring that their original performance is maintained during use.
