color of magnetic compound:

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

shape of magnetic compound:

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

storage of magnetic compound:

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 of magnetic compound:

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 HSMAG, the written approval of sampled quality is proof of functionality. Further guarantees are not assumed by HSMAG

Procedure Summaries of magnetic powder

a. Before production, the powders should avoid being humidified, and avoid being mixed with other material and impurity.
b. The mixture ratio of binders and plasticizers should be defined according to the grade of the powder. The powder and binders and plasticizers should be mixed uniformly.
c. The working temperature of extruding should be controlled between 50oC to 90oC. (calendaring plate is usually between 80oC to 120oC)
d. Please adjust the extruding speed, calendaring speed and times, according to the property required.
