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.
