Pneumatic tubes polyvinylidene fluroride

PVDF Manulef

MANULEF® tubes are made from virgin kynar 740 polyvinylidene fluroride and are produced by calibrated extrusion.

This material appeared on the market in 1955 and is used in translucent grade.
Kynar® is a trade name of the Arkema company® .
MANULEF® tubes are :
- Very resistant to chemical products.
- Resistant to temperature.
- Provided with very good mechanical properties.
- Insenstive to ultraviolets.
- Very impervious.
- Food quality.
- Nonflammable (UL 10).
MANULEF® tubes are intended for severe conditions of temperature and chemical aggression.
Their admissible working temperature ranges from -20°C to +150°C with very good dimensional stability.
They are also of food quality and have approval by the american FDA (Food & Drug Administration).
They are particularly adapted to outdoor use by their insensitivity to ultraviolet-visible rays and are imputrescible and insensitive to mould.
MANULEF® are supplied unnmarked.
Admissible working temperatures of MANULEF® tubes are between -40°C and +150°C.

Table of working pressure ratios of MANULEF® tubes with regards to working temperature

T(°C) -20° to +23° 40° 60° 80° 100° 120° 140°
Pressure (%) 100% 80% 70% 61% 46% 33% 25%

The values of working pressure ratios according to working temperatures indicated above represent only the average of the results obtained from burst pressures divided by a safety factor, given that these are variable according to tube diameter and wall thickness
