Hydrophobic Acoustic Mesh - Allows air to pass, but stops water
This fine mesh is precision-woven of a smooth polyester plastic (PET) monofilament and treated with a hydrophobic coating. It allows air and sound to pass but stops water, dust, and other contaminants. Be aware that water under pressure is able to can pass through the mesh. The mesh restricts airflow (and thereby sound) less than meshes and fabrics made from spun yarns and the mesh therefore has a high and consistent acoustic transparency.
What are Hydrophobic Acoustic Meshes used for:
The mesh is placed in front of speakers and microphones to improve sound quality and protect against dust and water. It is widely used on mobile phones and earphones.
The mesh is available with pore sizes from 7 μm to 285 μm in a range of colours. It can be coated with metal to shield electronics against electrostatic discharge (ESD) and protect cellphone users from electromagnetic waves.
Create covers for portholes on boats to allow fresh air to pass while stopping sea sprays.
You get three different product variants of hydrophobic meshes. The samples measure 9 cm x 9 cm. The black samples have a hydrophobic coating. Try dripping water on both the black samples and the metal-coated silver-coloured sample.
All samples come with a laminated information card, which includes contact details for the supplier.
QUESTIONS & ANSWERSAsk a Question
I want to use this to put over a window fan to block light but allow air to pass through, will this reduce airflow too much and does it block light?
The amount of both air and sunlight that passes through the mesh depends on the pore size of the specific variant of the material. You will have to test different variants in order to evaluate if it works for the intended application.
I am looking for a fabric in order to protect a microphone array from the rain. The fabric should be sound transparent and waterproof. Do you have a fabric that can satisfy these requirements?
The hydrophobic acoustic mesh is made for exactly this type of application. But be aware that water will pass if the textile is subjected to direct heavy rain or water under pressure.
I want to drill ventilation holes in an old Macbook and use this material to cover the holes. Is it possible to attach it to the inside of the holes with tape?
We only sell the material sample you see on the webshop. You can cut the shapes you need with a laser cutter and attach the adhesive yourself. You need to find a company who does "tape conversation" and assembly to have larger quantities made.
