Estimating the term…
The disclosure relates to a tube comprising a flame retardant layer and anouter layer, where the outer layer envelops the flame retardant layerand the flame retardant layer comprises a thermoplastic materialand expandable graphite particles. The expandable graphite particles are designed to expand above a starting temperature, and the expandable graphite particles are in a nonexpanded state. The outer layer has a thermoplastic material, and a center roughness value Ra of an exterior side of the tube or an exterior side of the outer layer measures less than or equal to 200 or 100 or 50 μm.
A tube comprising a flame retardant layer and an outer layer, wherein the outer layer envelops the flame retardant layer, wherein the flame retardant layer comprises a thermoplastic material and expandable graphite particles, wherein the expandable graphite particles are configured to expand above a starting temperature, wherein the expandable graphite particles are in a nonexpanded state, wherein the outer layer has a thermoplastic material, and wherein a center roughness value Ra of an exterior side of the tube or an exterior side of the outer layer measures less than or equal to 200 μm.
