Food grade ABS plastic is the first to comply with the FDA food safety certification of abs plastic, in line with the food grade ABS plastic grades are Taiwan Chimei ABS PA-737, BASF ABS 2802HD, BASF ABS 2802-TR, Sharp Basis MG38F, Sharp Basis ABS HP20 which are several.
Users need to pay attention to food-grade ABS plastic is not edible, the reason why it is called food-grade, mainly because of its material can be in direct contact with food, non-toxic, but there is no food-grade labeling of plastics can not be in direct contact with food, if the direct contact, it will affect food safety.
Extended information:
Precautions:
1, need to use a higher material temperature and mold temperature, the flow resistance of the casting system requires less. In order to avoid large stress near the gate under high injection pressure, which will lead to deformation of the plastic parts, lug-type gates are usually used.
2, pay attention to the selection of the location of the gate.
3, injection mold ejection structure should be designed reasonably.
4, in order to prevent the injection mold exhaust bad situation, in the design of molding this material mold, in the opening of the mold exhaust depth can not be greater than 0.04mm.
