Material

Every product range includes special grades for processing by extrusion. They are characterized by higher viscosity and melt stiffness in a broad processing window. Extrusion grades with special properties are also available, e.g. flame-retardant or UV-stabilized products.

Makrolon^® (PC)

Profiles made of Makrolon^® are used in a wide variety of applications. Makrolon^® is used for luminaire covers, in particular, because of its outstanding optical properties and its heat deflection temperature. It is also used in multi-wall profiles and connecting profiles of various sizes and geometries.

The branched grade Makrolon^® 1243 is recommended for profile extrusion. As a result of being branched, this grade offers a higher melt stiffness, which makes a major contribution to improved sizing.
High-viscosity, linear grades can also be used, such as Makrolon^® 3103 MAS157. Both Makrolon^® 1243 and Makrolon^® 3103 MAS157 are fundamentally stabilized against UV light.
A special weather-resistant layer is applied by coextrusion for outdoor applications. The following combinations are recommended for this purpose:

The following additional grades are also used in profile extrusion, depending on the application:

Bayblend^® (PC+ABS)

In principle, every Bayblend^® grade can be used for profile extrusion. Again, products of relatively high viscosity are best. Bayblend^® is used for profiles in the automotive industry, as well as for profiles in the electrical installation sector, e.g. for cable ducts and busbars. Grade Bayblend^® FR 3030 is recommended for standard applications.
