With the ban on decabromodiphenyl ethane, many white or colored materials that rely on bromine-antimony flame retardants have been greatly restricted, especially in the rubber industry.
Flame retardant HF-1204 is a halogen-free and red-phosphorus-free flame retardant developed by our company for manufacturers producing flame-retardant products made of EPDM rubber. It features small particle size and concentrated distribution. It appears as a pure white powder, fluffy and easy to disperse, and also relatively prone to dusting. When added as an EPDM flame-retardant filler, measures should be taken to overcome its tendency to dust; it should be added in multiple small portions to ensure the actual addition amount matches the designed formulation. The raw materials used to produce HF-1204 are strictly controlled by our company and fully comply with various environmental standards, making it an environmentally friendly and qualified product.
Usage method: For reference, we tested with an EPDM pre-mixed compound provided by a customer. The hardness of this pre-mixed compound after direct vulcanization is 56 degrees. When formulated with 80 parts of the pre-mixed compound and 20 parts of HF-1204, the resulting flame-retardant material can achieve V-0 rating at 1.6 mm.
For other applications, because the goals of different engineers may vary, the flammable components in the rubber may also differ. Simply copying the above proportion may not achieve the desired flame-retardant effect. Therefore, we recommend conducting small-scale tests and inspections first to determine the appropriate ratio. Generally speaking, the larger the proportion of flammable components, the more flame retardant needs to be added.
Safety: This product is mild in nature and will not cause harm to the human body upon contact during normal use. However, due to its fine particle size, good dispersibility, and tendency to dust, workers should wear dust masks during production and use.
Packaging and storage: This product is usually packaged in woven bags lined with PE film bags, with a net weight of 20 kg per bag. It should be stored in a dry, cool indoor area, protected from sunlight, rain, and packaging damage, and kept away from contamination by other substances.
