Which is better, abs or silicone?

Both materials are very good.

ABS material is a tough engineering plastic with high strength, hardness and impact resistance, as well as good wear resistance and chemical corrosion resistance. Therefore, ABS material is suitable for all kinds of occasions that need toughness, such as furniture, sports daily necessities, sports equipment and so on.

Silica gel is a soft synthetic rubber material with good elasticity and temperature resistance, and can be made into solid or liquid as required. Silica gel is non-toxic, odorless, chemically stable, insoluble in water and any solvent, soft in texture and resistant to high temperature, so it is widely used in infant products, drinking water equipment, medical supplies and other fields.
