White PVC forex board refers to a rigid board made of polyvinyl chloride substrate through closed-cell foaming process. Its technical characteristics are reflected in the balanced relationship between molecular structure stability and physical properties. The material is a homogeneous single-layer structure, the surface is calendered to form a dense cortex, and the internal honeycomb pores are evenly distributed through gas permeation control.
The material advantage of white PVC forex board lies first in the use of closed-cell foaming technology. Independent closed air chambers form an effective water molecule penetration blocking layer to eliminate capillary water absorption. The cross-linked polymer chain structure gives the board isotropic strength, and the longitudinal bending modulus is consistent with the transverse tear resistance. The surface dense layer provides a printable base, and the polar molecular structure ensures ink adhesion.
It also has weather resistance, which relies on the synergistic effect of ultraviolet absorbers and free radical scavengers. Light stabilizer molecules are embedded in the polymer network to block the photooxidation chain reaction. The heat deformation temperature is adjusted by the rigid groups of the molecular chain, and the dimensional stability is maintained in a high temperature environment. The plasticizer migration inhibition mechanism prevents brittle fracture in a low temperature environment.
The most important value of white PVC forex board lies in its multifunctional integration characteristics, which can simultaneously meet the needs of structural support, visual communication and environmental tolerance.
