MANULAN® tubes are made of solid polyurethane (thermoplastic polyurethane elastomer or TPU) polyester base.
They are obtained by calibrated extrusion.
If they are less durable in time than MANUril® tubes, they have acquired great importance on the market through their flexibility and their higher resistance to impacts and abrasion.
Moreover, the size of logic panels can be reduced by the low bend radius of MANULAN® tubes. MANULAN® tubes are :
- Very resistant to abrasion, wear and impacts.
- Very flexible, even in cold.
- Generators of very low pressure drops.
- Provided with good bend radius.
- Exempt of exudable plastifiers.
MANULAN® standard polyester base tubes are used in pneumatic or hydraulic logic systems and have excellent resistance to oils and hydrocarbons, but do not resist very well to acids and alcalines.
On request, it can be supplied in polyether base polyurethane, the other great family of polyurethanes.
Globally, tubes in polyether base polyurethane have the opposite characteristics.
A table can be found on page 19, giving the main differences in chemical resistances of polyester and polyether base polyurethanes.
MANULAN® tubes are rigorously calibrated. for certain dimensions, they are in conformity with NFE 49 101 which defines not only dimensional tolerances but also working pressures according to safety factors with regards to working temperature, along with tests (moisture absorption, aging, flexibility) defining their use.
They are made from 100% virgin material.
Marking of tubes is as follows : “tecalemit flexibles - part N° - manulan - ID x OD - batch N°”
