Kostil® B 366

About
Kostil B 366 is a Styrene-Acrylonitrile copolymer with a good chemical resistance and a very low residual monomers content. This easy flow grade exhibits a high clarity and it is designed for the moulding of items with complex shapes and/or with thin walls with fast cycles. Designation: Thermoplastics ISO 4894-SAN 2,MRS,105-25 Applications: Lighting, bathroom furnishing, catering (cups, trays), stationery, toys, displays. Cosmetic, medical and pharmaceutical items. Kostil B 366 is available in some standard transparent colours (2000, 2030, 2050). This grade, in natural version, complies by composition with the requirements set by the main Regulations for plastic materials intended for food contact (included the EEC Directive 90/128 and following amendments).&&
