About Us

The Diskit Sales Division of Perry Chemical and Manufacturing has been in the sanding pad business since 1963 when it entered into an agreement with the original patent holder. Diskit Sales provides sales and marketing services for a proprietary line of sanding pads manufactured by Perry Chemical for distribution to the auto aftermarket, industrial, woodworking and other industries requiring the use of sanding pads for precise control of the sanding operation. Diskit has been widely accepted as a high quality sanding pad with excellent wear and performance characteristics.

Diskit has long been known for its die cast metal hubs, which was introduced in the mid 1960’s. This hub is the strongest on the market and can withstand the most severe and abusive environment. Diskit distributes the die cast hub with a variety of designs including the flex edge design. Pad sizes range from 3” diameter to 8” diameter with various levels of hardness and various face materials for use with adhesive, PSA backed sand paper, looped backed sandpaper and non-woven abrasives.

In 2000, Diskit introduced a product line that focused on a polymer hub. This version provides the capability for dust free sanding and low profile pads. These pads are designed for medium duty service. These pads provide excellent performance at an economical price. Sanding sticks were also introduced in 2000 to replace the paint sticks currently used in most body shops.

Perry Chemical and Manufacturing is the largest manufacturer of back-up sanding pads in the United States and most likely worldwide. With an annual capacity of nearly 3 million pads per year, Perry Chemical supplies sanding pads to the largest OEMs and distributors throughout the U.S. These customers rely on Perry Chemical’s expertise in the design and molding of these pads. The proprietary chemical technology allows Perry Chemical to provide full line of products from firm to soft and with a full range of face materials without losing physical properties.

Warren P. Thayer Jr., a chemical engineer, founded Perry Chemical and Manufacturing in 1961. In 1963, he licensed the patent to manufacture polyurethane sanding pads. Over the years, Perry Chemical has used their strong technical base to become the leader in the production of sanding pads. Perry Chemical is the only sanding pad manufacturer that specifically blends its own proprietary chemicals. The proprietary polyurethane foam formulations provide superb adhesion between the face, foam and plate or hub assembly. The foam formulation is unique to the industry and provides a high abrasion resistance during application. With six base formulations, Perry Chemical can tailor the foam to meet a customer’s requirements for weight, foam hardness, face material, and strength to meet the ever-increasing need for higher rpms.

The development of many different designs of sanding pads is our specialty. With our highly equipped machine shop, Perry Chemical fabricates 99% of all the tooling required for our manufacturing process. Our tool room is equipped with the latest CNC lathe and mill equipment, which allows for reduced development times for a customer’s requested sanding pads.A dedicated development area provides a development to production mentality during the development process. Though sanding pads can be developed in time frames as short as one week, obtaining special raw materials can increase the lead time on new products.

Perry Chemical provides the highest quality pads in the market. From its fully equipped Chemical Laboratory to its sanding pad Performance Testing laboratory, Perry continually monitors the quality of raw materials and finished pads to insure their performance in application. The chemical laboratory is equipped with a Gel Permeation Chromatography unit, Fourier Transform Infrared Spectrophotometer, Brookville Viscometer and other laboratory equipment necessary to monitor quality and identify process anomalies. Our Performance Testing laboratory is equipped to perform all the industry standard performance tests such as RPM, face peel, hub bond, face run-out and flatness, durometer, etc. We are able to test sanding pads to 30,000 rpm with various ramp configurations. During the manufacturing process over 1% of the sanding pads are tested to destruction to insure the performance of the pad. In addition, the sanding pads are 100% visually inspected at three points in the manufacturing process to insure visually acceptable and long performance of our pads. Our efforts have resulted in less than 0.04% of our sanding pads being returned for replacement each year.

Our manufacturing process is constructed to provide efficiency for the production of all levels of orders. The process equipment is located for optimum utilization and flexibility so that the wide range of products we provide can be supplied on a monthly time schedule. The expertise of our production personnel continues to be the cornerstone of the company. Their job experience ensures the correct manufacturing techniques are utilized during the fabrication and packaging of the customer’s product. We provide a wide variety of packaging configurations for the delivery of the sanding pads ranging from bulk pack to point-of-purchase sale. Our technical and purchasing personnel can assist in the design and procurement of specialized packaging to meet the customer’s needs.

Diskit Sales and Perry Chemical are dedicated to providing the best service to our customers and innovative ideas in the development of sanding pads.
