Modified magnesium hydroxide

Producer& LocationLongmore, China


Longsafe 06B is modified magnesium hydroxide, as a low-smock flame retardant used in the rubber industry to enhance the flame resistance of rubber. Visual description: Longsafe 06B is a white powder.

Recommendations for application

Longsafe 06B can be used in EPDM and NBR for extrusion and molding black, colorful and white products, which can gives low smoke density, high strength and high oxygen index.

Longsafe 06B can replace the traditionally used antimony-bromine system. During the production, usage, and combustion of the rubber products, toxic and harmful gasses will not be produced, meeting environmental standards of RoHS, PaHS, REACH, and related legal requirements.


Longsafe 06B is commonly used by adding 120 % parts by weight of the rubber and oil products.

Adding zinc oxide (ZnO) or other fillers during initial mixing will improve the dispersion of the Longsafe 06B into the product.

Packing and Storage

Longsafe 06B is packaged as 15 kg/bag. When this product is stored away from direct sunlight in a cool, dry, and well-ventilated area, it should have a shelf life of at least twelve months.

Testing formulation:

   Formulation 1

   Formulation 2

                The condition of compression set: 100*24h,compress 25%.

                 It can meet the requirement of DIN5510. If the smock density need lower, cut F2-70GE and add 15phr
                 Longsafe 06B more.
