Technical Specifications

Frequently Asked Questions

What is the purpose of the durometer rating?
The durometer rating measures the hardness of the rubber, which determines how much the pad deflects under polishing pressure. A 90 durometer pad is relatively firm, suitable for specific polishing stages where precise geometry control is required.

Is this pad compatible with all polishing machines?
It is designed to fit standard 5-inch polishing platens. Please check your specific machine manual to confirm compatibility with 5-inch circular pads.

How often should the polishing pad be replaced?
Replacement frequency depends on usage volume and the specific connector type being polished. Operators should inspect the pad surface regularly for signs of wear or indentation.

Does the color indicate the hardness?
Yes, the black color represents the 90 durometer specification for this product line, allowing operators to distinguish it from pads of different hardness levels.

Can I use this pad for hand polishing?
This pad is primarily designed for machine-based polishing processes where consistent pressure and motion are required.
