Flame Retardant Hes-2 Ecoflame S-2000

Sulphonate Flame Retardant

Chemical Name: Sulphonated Flame Retardant Blends
Brand Name: EcoFlame S-2000
Equivalent Grade: Arichem HES FR-2
CAS NO.: N/A
Chemical formula: N/A

Application:
EcoFlame S-2000 is a non-halogen efficiency mixed metal salt of aromatic sulfonates
Providing extremely effective flame retardant (FR) performance in transparent and opaque
Polycarbonate (PC). The product was developed using Unibrom's high purity sulfonation
Technology.

EcoFlame S-2000 is a high efficiency product used especially for flame retarding PC. The
Product is specifically designed to produce a high level of transparency in FR PC. The
Active sulfonate content of EcoFlame S-2000 is much more than that of Potassium
Perfluoro-butyl sulfonate (KPBS) and other sulfonate FR products. FR effectiveness has
Been shown to be related to sulfonate content.

Product Description and Use or Loading Levels

Non Halogen Polycarbonate formulation

EcoFlame S-2000 is used at fractional loading levels typically less than 0.1% for UL94 V0
Flammability performance at 1.6mm thickness. Below is a starting formulation.

Formulation Component Loading %
Polycarbonate (6 MFI) 97.9
EcoFlame S-2000 0.1
Siloxane Anti-drip 2.00 *

*Various phenyl methyl siloxanes are referenced in patents and literature. Various trade
Name products are available: Shin Etsu KR2710, ShinEtsu KR 480, Dow Corning DC
8008, Momentive SR 476, Momentive SF 1550. The use of these products should be
Discussed with the silicone product supplier.

It has been noted in critical applications that EcoFlame S-2000 loading levels of less
Than 0.1% provide high transparency. This effect depends largely on the PC resin and
Anti-drip products used.

Polycarbonate formulation with Halogen Anti-drip for Opaque FR PC formulations

EcoFlame S-2000 is used at fractional loading levels typically less than 0.1% for UL94 V0
Flammabilityperformance at 1.6mm thickness. Below is a starting formulation.

Formulation Component Loading %
Polycarbonate (6 MFI) 99.7
EcoFlame S-2000 0.1
PTFE 0.2

Note that this formulation contains PTFE which contains Fluorine which is a halogen.
This formulation produces a translucent or opaque FR PC formulation. The resultant
Halogen level of this formulation is 1520ppm which is 100% from the PTFE

Packing:

It was packed in 10kg Drum, 270kg on pallet.


Note:
If necessary, silicon series flexibilizer was recommended in order to avoid any effection
With flame retardant formular.
