Non-Wovens

The surface condition of any part or product, whether for appearance or functionality, is a vital factor in meeting today's exacting expectations and competitive standards. Manufacturers worldwide devote significant attention to deburring, finishing and polishing systems to produce the results customers demand. Today many have learned to rely on a new category, non-woven abrasives. The unique three-dimensional construction of non-woven abrasives provides functional characteristics and a diverse range of performance capabilities that provide distinct advantages over traditional coated abrasives in many applications.

Marvel non-wovens are constructed from three basic components:

Fibre

By varying the dimension of the synthetic fibre, the firmness, or flexibility of the material can be manipulated.

Abrasive Grit

The size of the abrasive grain will influence the aggressiveness of the cutting action.

Resin Binder

This agent acts to bond the fibre and abrasive grain together and ensures the structural integrity of the finished product.

The way these three components are combined creates a variety of versatile abrasive tools capable of producing a wide spectrum of surface conditions and finishes. The characteristics of non-woven material have made it the fastest growing abrasive product today.

Why Use Non-Woven Abrasives?

Recommended Operating Speeds

One of the factors that most directly impacts the performance and ultimate success of any abrasive product is the use of the right surface speed for the application. Lower speeds are generally suggested for creating uniform satin finishes and for working on composites and soft materials such as aluminum. High speeds are recommended for deburring, and for removing and blending surface imperfections when faster cut rates and finer finishes are required.

Recommended Surface Speeds
Application Surface Feet Per Minute
Decorative Finishing 500 - 3000
Composites and other soft materials 1200 - 3000
Woodworking 1800 - 3000
Cleaning and surface conditioning 2000 - 3000
Preparation for polishing 2000 - 6000
Removal of surface oxides and discoloration 4000 - 6500
Deburring and edge radiussing 4500 - 6500
Surface blending and polishing
-Stainless Steel
-Carbon Steel

6000 - 7000
6500 - 9000
Cutdown prior to buffing 6000 - 8000

Chemical Resistance

Non-woven materials should not be used around or exposed to organic solvents, strong acids and alkali solutions.

Lubricants & Coolants

Although Marvel non-wovens can be used wet or dry, the use of lubricants and/or coolants can enhance performance variables such as product life, cut rate and heat generation. Typical solvents and/or coolants include water, oil and grease. We suggest the use of our Marvelube product, whose features and benefits are described in our catalog.
