Tuffak® CM-2
PC(聚碳酸酯)
阿科玛Altuglas (Arkema)
产品描述
Tuffak® CM-2 is the Altuglas International designation for Tuffak polycarbonate sheet with a durable, clear coating that significantly increases the abrasion resistance of Tuffak sheet in typical exposures such as washing operations, airborne dust and dirt, and non-abusive public contact. In addition, the abrasion-resistant coating significantly increases the weatherability and chemical resistance of Tuffak sheet and has essentially the same physical properties of the Tuffak polycarbonate substrate. The effectiveness of Tuffak CM-2 polycarbonate sheet has been established by laboratory tests and outdoor weathering.
Tuffak CM-2 sheets are coated on one or both sides and shipped with a protective masking on both sides. The sheets are supplied in a wide range of standard sizes and thicknesses in both clear and transparent tints.
