Brand: FLYHO     

Application: PC & PC alloy fluorine-free flame retardant & anti-dripping agent

Features and benefits: 

● Can achieve PFAS-FREE flame retardancy 

Composition:          

● Polycarbonate&Silicon-hydroxyl siloxane resin&Silicon-hydride siloxane

Overview: 

●Flyho  FLYHO KSI-402B is one of the fluorine-free anti-dripping additives  

It solves the problem of the presence of prohibited substances PFAS in the PC flame-retardant system.

1. In the PC flame-retardant system, it is recommended to add it at a mass ratio of 10-20%. At the same time,

 it should be used together with sulfonate and organosiloxane flame-retardant agents (SFR-Si907 is recommended). 

It can play a synergistic flame-retardant and anti-dripping effect, achieving the 1.6mm UL94 V-0 effect. 

Meanwhile, it can also pass the S2/60s needle flame test for flame retardancy.

2. The product contains no fluorine, phosphorus, bromine elements, or inorganic salt substances.

3.  Does not affect the physical properties . Instead, it effectively improves the physical property stability of the material, 

and the chemical resistance of the material.

4. PC flame-retardant material, HDT is approximately 120°C.

Application instructions

● Depending on different screw combinations, processing temperatures, and various requirements, there will be differences between the actual addition amount and the recommended dosage. 

● KSI-402B is added at 10-12%, it can achieve 1.5mm UL94 V-0 (near the gate end), and at the same time, it can pass the S2/60s needle flame test.

● KSI-402B is added at 19-20%, it can achieve 1.5mm UL94 V-0 (far from the gate), and at the same time, it can pass the S2/60s needle flame test.
