Best Design Backing Plates | Built-in Heat Management, Smooth Contouring, Perfect for High-speed Polishers

For a car polishing machine to perform the best, it needs a reliable backing plate and polishing pad, which collaborate to bring the best result. The car polisher, plate, and pad are all separate objects with different types, sizes, and material construction; however, they work together to polish the painted surface with job requirements and processes. We will review details about the backing plates and explain why MaxShine plates bring the best results. Below is a typical configuration of a polisher, plate, and pad configured for polishing ready.

Professional Polishing Plates

What is a polishing backing plate?

A polishing backing plate serves as an intermediary between the polisher and polishing pads. A polishing pad cannot be attached directly to a polisher due to the nature of the polishing pad, which is soft without enclosure while working with painted surfaces. The backing plate needs to transfer the circular or dual-polishing action to the polishing pad while absorbing heat and pressure from the polisher, polishing pad, and polishing action on the painted surface. There are factors to help the smooth polishing action transfer from the polisher.

Backing plate for DA polishers

The backing plate for DA high-speed polishers consists of the main body, polisher interface thread with a bolt, reinforced steel struts, vented holes, and hook and loop fastener, a typical configuration of high-speed DA Polishers. Some variations of the plate configuration exist to meet specific polisher requirements. For example, one of the MaxShine DA Polishers developed for a standard backing plate for M8S V1 and M8S V2 have six(6) vented holes; however, the MaxShine Da Polisher Pro version has eight(8) vented holes providing better heat absorption ideal for high-speed DA polishers.

The characteristics of the DA Backing Plates

  • Material construction: Most MaxShine polishing backing plates are made of Polyurethane, known to be heat resistant, elastic, and absorb vibration.
  • Thickness: The thickness of the pro version is 14mm, while the other DA polishing backing plates measure 10mm.
  • Center hole: A bolt thread to bind the backing plate to a polisher
  • Thread size: Most of the backing plates support 5/16″ thread size for DA polishers, with the exception of the 3″/6″ of M8S / M8 Pro plates.
  • Reinforced steel struts: Steel struts of 4 or 6 near the center help to maintain balance and apply pressure evenly to the pad.

  • Hook and Loop: Adaptation of hook & loop fastener of Maxshine backing plate allows effective attaching and detaching pad. 
  • Tapered Edge: The tapered edge minimizes direct contact with the surface, helping to smooth contouring and minimizing air pressure in high-speed orbital motion.
  • The 6 or 8-hole vented design makes easy air flows, ensuring the plate cools down and providing thermal 

Backing plates for Rotary Polishers

A rotary polisher works for a job that requires heavy buffing with extensive areas and cutting deep into the painted surface. To meet that requirement, the construction of the rotary polisher plate is more durable than the DA backing plates. MaxShine provides 1″, 2″, 3″, 5″, and 6″ backing plates covering most of the possibilities that a rotary polishing needs.

The characteristics of the Rotary Backing Plates

Due to the extensive coverage and requiring more cutting power of a rotary polisher, typical rotary backing plates are molded into one piece to endure pressure and harsh circular action. The one-piece design is one of the differences between the DA backing plates and Rotary backing plates.

  • Benefits of Molded One-Piece Design: The durable molding design allows extensive coverage and heavy buffing, easy and safe contouring on the painted surfaces, including curves and body lines with high elasticity.
  • High-quality Polyurethane: The high-quality material construction provides excellent durability and versatility for longevity, allowing it to be used more than 10,000 times.
  • Hook and loop: The hook and loop fastener makes attaching and replacing pads easy and provides strong bonding.

What is a Hook and Loop Fastener for polishing the backing plate?

A hook-and-loop fastener, also called the Velcro fastening system,  provides an easy way to attach or detach a polishing pad, made of nylon, polyester, and polypropylene supplied as woven tapes, reusable over time. polisher backing plates - hook and loop fastener

Since a car detailing process requires polishing varying degrees of areas and shapes and the depth of targeted polishing areas, frequently polishing pad varies by a specific task. Thus, the hook and loop fastener is an ideal solution for car polishing.

What are the benefits of polyurethane material?

Polyurethane is used in wide applications in intensive applications, proven to be heat and chemical-resistant, durable, and has strong bonding properties, making it perfect to use for a polishing backing plate, which deals with high heat, pressure, and chemicals.

The excellent bonding property of the Polyurethane allows for integrating thread to the polisher and hook & loop fastener and withstanding the harsh polishing operation. Chemical structure of Polyurethane polishing backing plate - polyurethane chemical structure

What is tapered edge and how does it help polishing?

A tapered edge is a unique 45-degree slope on a polishing backing plate for reducing air friction while the plate rotates at high speed, assisting easy and smooth contouring. polisher backing plates - tapered edge

It also helps to minimize direct contact with painted surfaces when a polisher is leaning toward the surface.


MaxShine brings all the possible dual action and rotary polisher plates, reliable and suited for specific requirements of buffing jobs. To meet high-quality and efficient polishing results, MaxShine produces backing plates that are pressure and heat-resistive products using the best material science and structural design.
