• GFR-GS04 is intumescent nitrogen-phosphorus based flame retardant.
• Conform to RoHS environmental protection laws and regulations.
• Small dosage of GS04 (around 10%~20%) sufficiently achieves VW-1 requirement while most physical properties and mechanical strength of the plastic materials can be well preserved. The unique nanometer inserting dispersion technology (nano-inserted dispersion tech) demonstrates the astonishing dispersion effect as transparent materials can keep their original transparency after processing.
• Good thermostability, suggested range of processing temperature (160~190 ℃)
• Good industry utility (be able to meet different requirement of flame-resistant grade V0, V1, V2, VW-1)
• Close to PH value neutral (6~7), no negative repel phenomenon with other assistants
• High weathering, water and oil resistance
• No black smoke or only small quantity of smoke generated when burning

GFR series in processing merit

1. Extremely high performance in polyester TPU.
2. Easily processed by ordinary equipment, such as kneading machine or twin screws and so on.
3. No caustic gas when processing
4. The flame-resistant TPU still maintains high mechanical strength and most physical properties after processing
5. Easily processed to make high concentration TPU master batch that can be widely used in different needs of further processing.

• We suggest GFR-GS04 is used alone as the flame retardant, so that most physical properties of TPU can be well preserved.
  
• When mixing GFR-GS04 with the plastic material by concurrent twin screw equipment, we suggest the flame retardant should be added from the side in order to achieve the best homogeneous mixbility. The processing temperature cannot be excessively high and the ordinary screw rod configuration will be appropriate.
  
• Suggestion of processing conditions:
  

Lays aside dry, cool, the seal place

15Kg enhanced paper bag and the third enhanced PE bag inside.
