Flame retardant for Rubbers yoho-692

Yoho-692 is a halogen-free environmentally friendly flame retardant used in rubber, with good phosphorus-nitrogen synergism.
The appearance is white powder, the surface has been modified, with small particle size, high temperature resistance, uniform dispersion and other advantages.
The processed products have good temperature resistance, good thermal stability, and do not spray frost and pollute the surface of the products.
Comply with EU RoHS, REACH and other environmental regulations.
Availability:
Quantity:
  • yoho-692

  • Yoho chemical

Advantages: 

1, good flame retardant effect, flame retardant grade can reach 0.5mm thick UL94V-0;

2, small smoke production, high oxygen index;

3, good dispersion in rubber, will not stick roll;

4, good thermal stability, can withstand most of the vulcanization process without thermal decomposition;

5, does not affect the vulcanization of rubber, the effect on the physical properties of rubber after vulcanization is small.

Quality index:

Appearance: white powder 

phosphorus mass fraction >20% 

nitrogen mass fraction >16% 

purity >99% 

average particle size <10μm


Application: Suitable for rubber flame retardant, good flame retardant performance, suitable for making thinner products flame retardant.

Products about 0.5mm thick can achieve UL94V-0, and the product oxygen index can reach more than 32.

Application recommendations: The amount of flame retardants added is related to the formula and vulcanization system of the product, of which the total amount of raw rubber and oil in the rubber has a greater impact on the amount of flame retardants added, and the percentage of flame retardants added is usually 30%-40%.

Add the appropriate amount of flame retardant according to the specific formula.

Note: If vulcanized with peroxide system, 10phr flame retardant can be appropriately added.

Packing: 25kg bag, lined with kraft paper bag.
