Differences between sintered & unsintered ptfe tape

More popularly known by the brand name Teflon, PTFE, or polytetrafluoroethylene, is an electrical insulator used in making high-grade cable and wire. PTFE tape is revered as a superior insulator for many qualities, including low dissipation, wide temperature tolerance, high-frequency stability, low smoke generation, resistance, dielectric constants and its resistance to flame, chemicals, solvents, moisture […]

Furnace types

Single-stage:A single-stage furnace has only one stage of operation, it is either on or off.This means that it is relatively noisy, always running at the highest speed, and always pumping out the hottest air at the highest velocity. One of the benefits to a single-stage furnace is typically the cost for installation. Single-stage furnaces are […]

General sintering

Sintering is effective when the process reduces the porosity and enhances properties such as strength, electrical conductivity, translucency and thermal conductivity; yet, in other cases, it may be useful to increase its strength but keep its gas absorbency constant as in filters or catalysts. During the firing process, atomic diffusion drives powder surface elimination in […]

Sintering mechanisms

Sintering occurs by diffusion of atoms through the microstructure. This diffusion is caused by a gradient of chemical potential – atoms move from an area of higher chemical potential to an area of lower chemical potential. The different paths the atoms take to get from one spot to another are the sintering mechanisms. The six […]
