Zylar 550
Methyl Methacrylate Butadiene Styrene (MBS)
DESCRIPTION
The product line Zylar® comprises blends from styrene, butadiene and methylmethacrylate copolymers (MBS). The blends are highly
transparent, tough and show a good chemical resistance. Depending on the application, they can be a low density alternative for
polycarbonate, PET-G or transparent ABS (MABS). The grades are suitable for medical applications, food contact statements are available
upon request. Zylar®550 provides a good balance between transparency and toughness.

SUPPLY FORM
Zylar resins are available in bulk, 25kg bags or octabin cartons.
PROCESSING
Zylar is a low moisture absorption copolymer and in many instances processes readily without pre-drying. There are combinations of
conditions that require the product to be dried, such as high humidity and heavy section molding. Two hours at 60 °C (140 °F) is adequate for
most applications. Dehumidifying type driers are recommended. To obtain maximum clarity and gloss from this product, it is necessary to

have a highly polished mold. Design of gates, runners and sprues can be patterned after standard practice for high-heat polystyrene. All mold
surfaces must be temperature controlled at 54 °C (130 °F) for optimum clarity and surface gloss. For optimum clarity, machine cylinders,
barrels, screws, valves, etc. should be thoroughly cleaned before processing. Contamination by other materials will cause streaking or haze.
