Soft High Elongation Pad Silicone Conforms to Complex Recess Parts Hongye Silicone

Standard pads at 30 Shore A struggle on recessed and curved parts. The first contact point bears the pressure, edges lift away, and the groove bottom picks up uneven ink. Relief depth, rounded corners and fine textures all push the pad to stretch and conform. Without enough softness and elongation, the transfer misses those areas.

What Makes HY-916 Stretch

HY-916 sets hardness at 14 Shore A and elongation at 570 percent, the most flexible grade in the range. The base polymer stays compliant so chains open up along the workpiece profile under load. The pad enters narrow slots without being ripped, while 25 kN/m tear strength holds it together over repeated impressions. The 36000±2000 mPa.s viscosity pours cleanly and degasses with few trapped bubbles.

How the Pad Conforms

On each press the soft head meets the surface, follows the contour, and carries ink to groove bottoms and corner radii. It releases and springs back without permanent folds, so later impressions match early ones. Fine type and logo edges stay intact instead of breaking where the head was too stiff.

When to Pick 916

Choose 916 for toy relief, cosmetic cases, stationery curves and electronic embossed logos. Flat high volume lines use 912, general arcs use 902, deep recesses use 916, precision food contact uses 933. Ready stock 1 kg MOQ, sample trial before bulk.
