Inovia DR-S15 is a new flame retardant designed for polycarbonate(PC), especiallyfor thin PC products. It doesn't contain halogen, nor needs PTFE anti-dripping agent to reach UL V0. It is the first case in the world that can afford PC UL 94 V0at athickness from 0.1 to 1.6mm, while remaining the optical properties of PCproduct.

1. Materials:

PC: Covestro 2805

Flame retardant: Inovia DR-S15

2. Processing:

2.1 Drying: PC Resin is dried at 120°C for 3 hours in a vacuum oven. Inovia DR-S15can be used as provided if its package is intact.

2.2 Extrusion temperature: 220~250°C

2.3 Casting temperature: 220~240°C； thickness of the sample: 0.5mm.

Note: DR-S15 flame retardant or its masterbatch MB-PC10C (10%) can be supplied. Adding the flame retardant will increase the melting index significantly, therefore, the processing temperature will need to be lowered accordingly, by around 20~30℃. The plastic or masterbatch will need tobe completely dried and the machine needs to be thoroughly cleaned, for ionic liquids has superior cleaning capacity.
