Inovia DR-S15 is a new flame retardant designed for polycarbonate plastic, especially for thin PC products (less than 2mm). 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 V0 at a thickness from 0.1 to 1.6mm while the optical properties of PC remain intact.

1. Materials:

PC: Covestro Makrolon 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-S15 can be used as provided if its package is intact.

2.2 Extrusion temperature: 235~270°C

2.3 Injection temperature: 235~270°C, mold temperature: 80°C

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 to be completely dried and the machine needs to be thoroughly cleaned, for ionic liquids has superior cleaning capacity.
