POLYAMIDE 12 HIPHL/PHL/PHLY DIN 74324 & 73378 HOSE
Manufactured for more than 40 years from oil sources (Laurynlactam), PA12 is a techno-polymer used in highly demanding applications on account of its excellent
properties:
- High dimensional stability
- High mechanical properties, particularly resistant to high pressures
- Outstanding resistance to harsh weather conditions
- Very good resistance to abrasion
- Excellent resistance to chemicals
- Wide operating temperature range (from -40°C to +100°C)
- High flexibility
- Excellent resistance to hydrolysis
PA 12 is widely used in air-brake systems for truck and trailers, automotive fuel lines, fluid and gas (including compressed air) lines where chemical resistance
and strength are crucial.
DIN 74324 is the norm which defined methods for testing the requirements of polyamide hoses used in air-brake systems.
