Product Material
The TrueLine Adapt components are manufactured with a high performance, engineering grade nylon. Often utilized for performance parts within the aerospace & medical industry, the material performs well under stress, extreme conditions, and adjacent / exposed to a variety of materials.
Maximum Device Weight
Maximum phone weight (assuming no phone attachments outside phone profile/ weight): 14oz
Allowable temperatures
Up to 180F with no significant alteration to material tensile strength.
Water Resistance
Material will withstand short term or moderate immersion with no measurable change in strength. Moderate immersion (<24 hours) may affect the stiffness / clamping power minimally (>7%), but will not change the appearance or overall functionality of the product.
Chemical Resistance
- Mild chemicals do not significantly affect the performance or material properties (ie motor oil, non concentrated soaps/washing solutions, antifreeze ) but may affect the aesthetic of the material.
- Incidental contact with greases should be avoided as prolonged exposure can affect the material long term strength.
- Incidental contact with moderate to strong acids should be avoided as they can significantly alter the material properties and function due to degradation.
The above conditions are for the Trueline Adapt™ components themselves. Optics and phones should not be subject to heat, moisture, chemicals. Heat, moisture and chemicals may compromise the adhesive used for the plate attachment and should be avoided even in incidental contact. Refer our FAQ section for more general questions or related topics for use of the Trueline Adapt™ products.
