Product description: Doher-998 is a compound halogen-free environmentally friendly flame retardant applied to rubber and silicone rubber, which has a good synergistic effect of phosphorus and nitrogen. Appearance is white powder with modified surface.

It has the advantages of small particle size, high temperature resistance and uniform dispersion. Processed products have high temperature resistance,

Good thermal stability, at the same time does not fade, does not spray frost, does not pollute the surface of the product. In line with Europe

ROHS, REACH and other environmental regulations.

Advantage:

1. High flame retardant efficiency, the flame retardant grade can reach 1.6 mm thick UL94-V0;

2. The amount of smoke is small and the oxygen index is high;

3. Good dispersibility in rubber, no sticking roller phenomenon;

4. Good thermal stability, can withstand most vulcanization processes without thermal decomposition;

5. Does not affect the vulcanization of rubber, and has little effect on the physical properties of rubber after vulcanization.

Quality Index:

Application:

Applicable to the flame retardant of rubber and silicone rubber, and has outstanding performance in EPDM rubber, flame retardant performance

It can reach UL94-V0 and oxygen index above 32.

Application suggestions:

For products with a hardness of about A65, the percentage of flame retardant added is about 35%. Addition amount of flame retardant

Not fixed, it is related to the formula of the product, especially the added amount of rubber oil. According to specific

Formulated with the right amount of flame retardant.

Reference recipe:

Note: If DCP system is used for vulcanization, 10phr flame retardant can be added appropriately.

Packing:

25kg per bag, lined with kraft paper bags.
