Lasing Polymers

When a component is lasered an amount of the substance is thermally decomposed (burnt off). This thermal decomposition, which is the fume, comprises a mixture of particulate and gas. Glass, ceramic and most base metals do not generate as much fume, so we will concentrate on polymers which do.

The gaseous organic compounds are known as Volatile Organics Compounds, VOC's. The table below shows the ratio of particulate to gas for a variety of plastic materials.

Non organic gases given off, that need capturing, tend to be acidic eg, HCL and for these applications a specifically designed media for acid gases is included in the gas filter. Click here for further information on acid gases applications.

The chart below gives a break down of the various chemical compounds produced when lasering various polymers.
