Grades for PC/PMMA Alloy
This product, when compounded with PC, can improve the low surface hardness which is a disadvantage of PC. It is available in SA256 (transparent) or SA232 (opaque) types. When the SA256 type 30% is applied, PC with a pencil hardness at the B level can be increased to the H level.
Change in the properties of the material when SA256 is applied, compared to the existing PC
SA256 has excellent optical properties compared to the general PMMA/PC material, due to forming a uniform morphology in the PC matrix by that improves the commercial properties of PC.
