Introduction
Sign panel pp plastic wholesale is processed and produced by high-density polyethylene material. It is a thermoplastic engineering plastic that combines the advantages of all plastics. It belongs to a kind of plastic board that is odorless, feels like wax, and has excellent low temperature resistance (low operating temperature can reach -70～-100℃). The plastic plate has good chemical stability, can resist the erosion of most acids and alkalis (not resistant to acids with oxidizing properties). What's more, it is insoluble in common solvents at room temperature. In addition, it has low water absorption, and excellent electrical insulation properties.
The sign panel has low density and strong toughness (also suitable for low temperature conditions). Moreover, it has strong tensile properties, good electrical and dielectric insulation. What must be mentioned is that the board is environmentally friendly. By adding flame retardant, the produced plastic board can be extinguished immediately after the fire in terms of flame retardant effect.

Sign panel pp plastic wholesale is mostly used for screen printing and flatbed digital printing of signs. After corona treatment, the surface tension level of our corrugated plastic sheet will reach no less than 46 dynes, which number is quite excellent for any UV printing or glue adhesion. Normally, corona treatment will decrease slightly over long storage time, but 2 years is a safe time for printing.
