flame retardant BX FR TBC

Product Description

• TBC features excellent thermal stability, high whiteness, low volatile content, and light processing color, making it particularly suitable for flame retardant modification of thermoplastics such as polyethylene (PE), polypropylene (PP), polystyrene (PS), PVC, HIPS , ABS, and EVA .
• Rubber: Various synthetic rubbers (such as SBR, BR). Btter heat resistance, UV resistance, blooming resistance than Methyl Octabromoether(cas 97416-84-7).

Key Features

characteristic	describe
High whiteness	Whiteness ≥90, suitable for light-colored/natural-colored products.
Good thermal stability	The thermal decomposition temperature is higher than that of similar products on the market.
light color	The color is stable at the recommended processing temperature, and the product has a good appearance.
Low volatile content	Low volatile content, less processing smoke, and mild odor
Anti-precipitation	When used with a suitable dispersant, migration and precipitation can be effectively inhibited.
Good compatibility	It has good compatibility with resins such as polypropylene and disperses evenly.

Application

4.1 This product must be used in conjunction with antimony trioxide (Sb₂O₃);

4.2. Depending on the material type and flame retardant rating requirements, the general addition amount is 5%-20%, and the specific addition amount needs to be determined. Adjustments are made based on the thickness, raw material grade, and equipment process.

4.3 It is recommended that the mass ratio of flame retardant to antimony trioxide be 3:1~4 ;

4.4 For formulations containing fillers such as talc and calcium carbonate, the dosage needs to be appropriately increased ;

Processing Guidelines

5.1 Drying

Normally, drying is not required. If the packaging is opened and the product becomes damp, it is recommended to air dry it at 80-90℃ for 1-2 hours.

5.2 Recommended processing temperature (PP injection molding)

Location	Temperature range (°C)
Rear section of the barrel	180-190
Middle section of the barrel	190-200
front section of the barrel	200-220
nozzle	200-205
mold	40-70

5.3 Precautions

1. Color remains stable during normal injection molding cycles .
2. It is recommended to avoid prolonged downtime (material should be removed if downtime exceeds 5 minutes).
3. It is recommended to use it in conjunction with a dispersant (such as EBS, polysiloxane, etc.) to improve dispersibility and resistance to precipitation.
4. It is not recommended to use with chlorine-containing pigments or phthalocyanine-based color powders, as this may affect the flame retardant effect.
