Why should PVC cable compound be sampled before bulk purchase?
Trial samples confirm extrusion behavior, appearance, performance and color on the buyer’s own equipment before bulk purchase.
PVC cable compounds with similar specifications may perform differently on different customer lines.
Extruder type, screw condition, temperature control, mold structure, line speed and cable design all affect processing behavior.
A sample trial checks plasticization, surface quality, diameter stability, odor, color, sticking, migration and other real production issues.
For cold-resistant, heat-resistant, transparent, matte, flame-retardant and compliant materials, trial production is especially important.
