A Medical Polyvinyl Chloride Compound is not defined by its base resin alone — flexibility, transparency, chemical resistance, and processing behavior all come from the combinatio...

A 90 °C halogen-free sheathing compound can pass the single-wire EN 60332-1-2 flame test and still fail the Cca classification written into the purchase order. EN 50399 measures ...

When a 132 kV cable fails its routine partial-discharge screen at 5 pC, the extrusion line is examined first and the compound is examined last. The order is usually reversed. Par...

Three hours into the first run of a low-smoke halogen-free sheath compound, the operator at a cable plant in Hangzhou watched the extruded surface turn chalky, a white ring form o...

Every metre of cable under a metro carriage floor is a potential fuel source, and inside a tunnel fire the real hazard is usually not the flame itself. Smoke, hydrogen chloride, a...

Every cable manufacturer has heard a variation of the same warning: a batch of low-smoke halogen-free (LSZH) compound extrudes cleanly, produces a smooth cable surface, and passes...

Two cable factories receive quotations for the same thermoplastic low smoke zero halogen (LSZH) sheath grade. One supplier quotes 15 percent lower, and its datasheet looks nearly ...

A cable producer qualified an LSZH jacket compound for a rail project and watched the extrusion surface turn rough within the first hour of production. Another buyer saw the same ...

When a 90-degree B1-grade LSZH sheath compound arrives at a cable plant, the first check a quality engineer should make is the batch-to-batch oxygen index, not the certificate. A ...

The Marine Fire Scenario That Drives Material Selection A fire on board a vessel is fundamentally different from a fire in a building. There is no street to walk to, no lobby to e...

A cable plant in Southern Europe approved a 90°C low-smoke zero-halogen (LSZH) sheath compound after three pilot batches cleared tensile, smoke, and aging checks. On the first ful...

Smoke, Not Fire, Decides How a Tunnel Incident Ends A metro tunnel does not behave like an open building. Smoke has nowhere to escape, combustion gases travel along ventilation fl...
