insulating compound

[′in·sə‚lād·iŋ ‚käm‚paünd]

(materials)

A liquid, at low temperatures, which is poured into joint boxes and allowed to solidify; as a poor conductor of heat and electricity, it provides good insulation.

9 Physical Review Letters, creates a magnetic form of graphene by precisely placing it above a magnetic, insulating compound. It's the first time researchers have magnetized graphene while also preserving the ultrathin material's other tantalizing properties, such as the super-speed of electrons coursing through it.

Graphene's allure can be magnetic: proximity allows carbon sheet to borrow a material's power

Kuka Systems' Sam technology allows automakers to use an acrylate acoustic insulating compound for vehicle sound-proofing, applied by a robotic cell, in place of the traditional bitumen or butyl mats that have to be custom-cut and hand-positioned.

Preventing this by cavity wall insulation is a far bigger project, although it causes little disruption since the insulating compound is injected through holes drilled from outside.

Make sure energy bills are not too hot to handle

The conformal material qualification standard IPC-CC-830, Qualification & Performance of Electrical Insulating Compound for Printed Board Assemblies has been in use since 1984 (revision B released in August 2002) and features a number of assembly standards addressing coverage requirements.

Injection Molding: The body of the heat sink is first injection molded using thermally conductive but electrically insulating compounds such as PolyOne's Therma-Tech thermal-management materials.

New 'dry' process puts circuitry on plastics: laser ablation and plasma etching team up to apply thicker conductive layers without a 'wet' plating process

With lead being the "historically" primary stabilization component in a wide variety of insulating compounds, agencies such as Underwriters Laboratories (UL) have expressed their intentions to require that wire and cable manufacturers resubmit product made with these compounds in order to maintain their existing types of approvals.

Q&A: getting the lead out: environmental concerns have forced compound vendors to reformulate PVC jacketing to exclude lead. What exactly does this mean for future wire & cable insulation?
