Choose Pad Silicone by Surface and Volume Hongye Silicone

Customers often ask which pad silicone is best. The answer depends on two things: the part surface and the production volume. Pick wrong and you get blurred edges, short pad life or wasted cost.

Match by Surface

Flat parts such as switch panels, battery covers, metal tags and PVC cards use HY-901. At 30 Shore A it prints sharp at the lowest cost. Arcs and slight curves such as toothbrush handles, combs, cup walls and charger shells use HY-902 with 430 percent elongation, so the head follows the curve. Deep recesses and irregular shapes use HY-916 at 14 Shore A, the softest grade that reaches into cavities.

Match by Volume

Small batch daily work uses HY-901 for best value. Two shift high cycle lines use HY-912 with 25 kN/m tear, the highest in the range, so heads change less often. Precision or food contact parts use HY-933 addition cure platinum at 9:1, 34 Shore A and ≤0.1% shrinkage.

Quick Rule

Flat take 901, arcs take 902, deep recess take 916. High cycle swap 901 or 902 for 912. Free samples let you test on the press before bulk order.
