Frequently Asked Questions
What is mold-on rubber? ›
Mold-on rubber features a thick rubber tread permanently bonded (vulcanized) to a cast iron core. It handles heavier loads than TPR and provides excellent shock absorption.
Are mold-on rubber casters non-marking? ›
No. Black mold-on rubber can leave marks on light-colored floors. For non-marking needs, choose gray TPR instead.
When should I choose mold-on over TPR? ›
Choose mold-on rubber when you need higher load capacity, better vibration dampening, or when floor marking is not a concern.
