Technical specifications
Windform® GT is a polyamide based glass fiber reinforced composite material with a dark black color. After hand polishing, the material is smooth with a deep lustrous finish.
It is a flexible product in the Windform® family of TOP-LINE SLS materials for Additive Manufacturing, not only aesthetically, but also in terms of performance. In fact it combines the optimal characteristics of elasticity, ductility, and resistance to impact.
Windform® GT is also a waterproof material, with resistance to the absorption of moisture and liquids. It is also very light with excellent mechanical properties per unit density. Moreover Windform® GT is not an electrically conductive material.
It has been rated HB according to the flammability UL 94 test and has passed outgassing tests for space missions.
Applications
Windform® GT can be considered a highly valuable material in various and functional applications in regards to vibration and shock (for example: racing components near the ground and under the hood).
The material’s superior values in regards to impact strength and elongation at break, combined with its tensile and flexural strength, make it ideal for applications where resistance to damage is a prerequisite in order to preserve internal components in the event of impact and/or improper use.
Its waterproof characteristics make it particularly suitable for many applications such as air ducts, intake and cooling systems, hydraulic ducts in contact with liquids or oils.
All these applications indicated above are just examples.
