Magnetic compound for Extruding fridge strip

YXF Brand Strontium Plastic Bonded Ferrite Magnetic compound are suitable for making various bonded magnets. They have good compatibility with different kinds of composite materials, such as nylon, resin, polyvinyl chloride and rubber etc.. Due to the large particle size, such powders have high filling capacity. They can be used for making different kinds of magnets by extrusion or infecting moulding. The strict quality control system of our plant ensures that the quality is stable and consistent.

COLOR:

White, black, gray, light yellow, light black, porcelain white, etc, anyway, specific hardness, color of PVC compound could be made as per customers¡¯ demands.

SHAPE:

Dimensions and tolerances as well as polarity correspond to the relevant valid YUXiANG drawing.

STORAGE

In general, long storage times in a humid and got climate may results in brittleness of the magnetic strip. The storage time should not exceed: 12 months at a storage temperature of up to 25 /50% relative humidity, 6 months at a storage temperature of up to 40/50% relative humidity.

In case of higher temperatures and humidities, the storage time should be reduced accordingly. The cartons should remain sealed during storage in order to avoid possible hardening of the magnetic strip caused by long-term exposure to light. Permissible stacking height for stationary storage: tree pallets on top of each other.

FUNCTION

We guarantee a series delivery according to specification. The customer determines the suitability of our products of the specific application by way of appropriated functional tests of series delivery. For Yuxiang, the written approval of sampled quality is proof of functionality. Further guarantees are not assumed by YUXIANG.

CHANGES

As the responsible supplier, YUXIANG reserves the right to make changes and modifications with regard to the enhancement and further development of the product mentioned in the contract, modifications to the specifications stipulated herein being excluded.
