Make and object bounce against something no matter its speed

Hello,
I want to make a 2d ball bounce against a wall,i’m using the classic unity physic system and it’s working fine overall but i have one little problem, when the speed/velocity of my ball is very low instead of boucing off it will follow the wall edges.

Is there a way tout fix that?

Thanks.

There is a bounce threshold value in the physics settings, just set it to a lower value.
