ProFlame® PNPO-G1
PNPO-G1 is a halogen-free flame retardant , which develops its effectiveness through phosphorus / nitrogen synergism. When incorporated into thermoplastics, which can meet the requirement of UL94- V0(0.75-1.6mm), GWIT 750°C, GWFI 960°C .Meanwhile ,PNPO-G1 can pass 70°C*168hrs water immersion test (UL746C) and meet ROHS and REACH environmental regulations .It can replace FP-2200S/2500S produced by Adeka.Its FR performance is better than PNPO-G ,Especially in GF-PP .
Benefits
•Compared with bromine-antimony flame retardant, the product density is lower and the comprehensive cost of formula is lower
• With high thermal decomposition temperature , excellent heat aging resistance and excellent UV
stability, it can adapt to a wide range of processing technology and application
• Compared with traditional ammonimum polyphosphate flame retardant,it has excellent precipitation resistance and better hydrolysis resistance
• Low smoke density and low smoke gas corrosivity,good recyclability

Remark: For Non-glass-fiber system, it is recommended to add 0.2-0.4% anti-dripping agent.
Processing instruction:
(1) On the premise of ensuring the dispersion of flame retardants and uniform blending, the processing temperature of the twin screw should not be too high. Avoid causing a small amount of decomposition of flame retardants, resulting in slight foaming. Do not add a sieve during the extrusion process, as it may cause foaming. At the same time, a certain degree of vacuum must be maintained during the twin screw extrusion process.
(2) Do not use substances in the system that have adverse effects on flame retardancy. For example, Cl containing pigments such as phthalocyanine green can lead to flame retardant failure. When the amount
of carbon black exceeds 0.5%, the flame retardancy decreases. Inorganic fillers (such as glass fiber, calcium carbonate, talc, Barium sulfate, etc.)will affect the flame retardancy.Adding additive containing Br and Cl can lead to the failure of flame retardants.
(3) Use a weak shear screw combination to avoid material decomposition caused by excessive shear heat
(refer to the recommended screw combination adjustment).
