CHEMICAL COMPOSITION

This range of polydimethylsiloxane have been “free-blown” with a chemical blowing agent and crosslinked with an organic peroxide. The cellular structure is produced without the use of CFC’s thus making less damaging to the environment.

FLAMMABILITY CHARACTERISTSIL16FR has a Limiting Oxygen Index (LOI) of 28%, the other products have an LOI of 23.2% (BS2782 Part 1) and comply with the following flammability specifications:

• FAR 25.853 (a)(1)(iv) and (a)(1)(v) horizontal flammability tests.
• CAA specification 8 issue 2 (2.2)(c) and (d) horizontal flammability tests.

MOISTURE ABSORPTION

The range has a very low degree of moisture absorption. Mechanical properties shows little change even after long periods of immersion.

PIGMENTABILITY

The product range is available in off-white as standard. Other colours, such as red oxide, are available, we can colour match to most customer requirements.

ENVIRONMENTAL RESISTANCE

Silicone rubber has excellent resistance to ozone, oxidation, ultraviolet light, corona discharge, cosmic radiation, ionising radiation and weathering in general. Typical radiation resistance is greater than 10 grays (greater than 10 rads).
