幕布特点
MG系列高清白塑是应用最广泛的前投幕布材料之一。由三层结构组成，表面为改良性白色PVC投影面，中间层是玻璃纤维，底层为黑色PVC。在白色PVC层的表面，由凹凸不平分布均匀的特殊形状组成，从而形成良好的漫反射效果，使画面的亮度更均匀，视场角更大。玻璃纤维由于具有良好的物理性能（5%收缩率）及耐候性，使得玻纤能够长期保持其平整性及不卷边的物理特性，从而保证整个投影面的平整性。底层黑色PVC具有阻光、不透光特性，保证投影的光线不会穿透幕布形成杂散光，从而影响观看效果。在色彩还原效果与对比度的表现方面，拥有良好的统一性。具有色彩还原性好、成像清晰、视场角大、光线柔和、耐候性良好等特点。
适用投影机：长焦投影机 （投射比＞1.2：1）
适用环境：暗光（50Lx）环境下

The white PVC is composed material with RoHs approved. The black PVC is the same material only with black to absorb transmission light. The three layers of material by the physical repression, formation of micro prism structure, make fiberglass screen also has a good diffuse reflection performance, let the projection screen light distribution more uniform, more soft and with a larger field of view Angle 160 °at the same time.
