How Electrical Conductors and Insulators Work Electrical conductors are materials that conduct electricity; insulators don’t. Why? Whether a substance conducts electricity depends on how easily electrons can move through it. Protons don’t move because, while they would carry electrical charge, they are bound to other protons and neutrons in atomic nuclei. Valence electrons are like outer planets orbiting a […]

An electrical insulator is a material whose internal electric charges do not flow freely; very little electric current will flow through it under the influence of an electric field. This contrasts with other materials, semiconductors and conductors, which conduct electric current more easily. The property that distinguishes an insulator is its resistivity; insulators have higher resistivity than semiconductors or conductors. A perfect insulator does not exist, […]

“acid cure” silicone rubber for electronics

Do not use “acid cure” silicone rubber for electronics. Neutral cure SRs will always say “neutral cure” or similar on the container. if they do not say this or similar they will be acid cure. There are 2 main types of neutral cure SR (= NCSR) in common use. There are a number of other […]
