Magna W120
Magna W120: Heat Resistant
The primary characteristic of Magna W120 is its strong resistance to heat (up to 90 degrees Celsius). It is also a highly robust material resistant to a wide range of substances, including solvents and oil. Excellent thermal performance makes Magna W120 suitable for a wide range of applications, including light fittings and in the internals of cars. Its strong resistance to corrosion also make it ideal for orthodontics.
Advantages
Resistant to heat, Excellent detail resolution, Easy to process and finish.
Applications
Automotive, Tooling, Wind tunnel testing, Temperature testing, Casings for electronics, Orthodontics, Light fittings.
