How to identify the good or bad silicone wire ?

Silicone wire is also known as silicone rubber wire (AGR), the industry is divided into high temperature wire, its low temperature resistance is also excellent, the temperature range is -60℃-180℃

3. Insulation layer identification thickness Is the thickness of the better, the answer is, because the insulation is too thick often means that the conductor diameter is not enough. Inferior insulation bending is very easy to crack the final insulation wrapped conductor more uniform means that the wire process more stable the better, such wire more durable, on the contrary, uneven insulation thickness for inferior products AGR line high temperature resistance, burn with a lighter, the insulation layer reaction the smaller the material the better.

Note: Silicone wire must be away from sharp things, Because it is easy to be scratched.
