摘要:
An interior surface panel such as a ceiling tile is free of PVC materials and otherwise possesses desirable properties that make it suitable for installation in a variety of environments including schools, household and commercial kitchens and healthcare facilities. The panel can include a base mat and a facing material of a polyolefin or polyester polymer or copolymer bonded to the base mat. The facing material is resistant to ultraviolet light and possesses superior scrubbability. The PVC-free facing has a preferred thickness, opacity and surface roughness and a texture pattern that is non-directional and discontinuous. In an embodiment in which the PVC-free facing is white, it has a preferred light reflectance. The PVC-free facing is resistant to deformation under tension. In addition, the facing has low anisotropy; that is, the facing exhibits minimal differences in its physical properties in different directions. The facing also has good dimensional stability.
