Felt, Acrylic, Wool, Cork, Silicone, or Rubber?

I use an SDS Isoplatmat on the Sol. It's a powder coated, laminated alloy mat I've stuck to the Sol platter using a non hardening acoustic sealant. The Sol platter and the mat are not grounded. I also use a CF dust bug which sweeps the record as it plays to keep the dust from accumulating on the needle. This too is not grounded. All my records are washed. It's winter, the windows are closed, the heat on. I have zero static issues.

What am I doing wrong?

I have no problems with static either but i use a humidifier in the winter months.
Keeping humidity at 40% indoors should minimize static.
