Constructed with thousands of micro-replicated gripping fingers, 3M Gripping Material GM640 provides a lighter, yet tighter grip for maximum hold with minimum effort. Designed to enhance grip and reduce slippage, this product is a soft gripping material. The nylon knit backing allows the material to be sewn to a variety of surfaces such as fabrics and leathers.
Improve gripping performance
Easily Enhance Your Grip
When mated with another gripping material, 3M™ Gripping Material GM640 provides good durability and high coefficient of friction properties. This soft, black gripping material utilizes 3M proprietary micro-replication technology to create thousands of tiny replicated fingers that enhance grip and reduce slippage. Used alone, this material provides a secure grip, but when used in conjunction with another gripping material, such as sewn into a glove and wrapped onto a handle bar, grip strength is maximized even in wet conditions. 3M™ Gripping Material GM640 is designed to be sewn using most commercially available equipment using a leather walking foot. With the best UV sunlight resistance of the gripping material products, this material is an ideal choice for exterior applications or those applications which will expose the material to some sunlight.
Recommended Applications
- Athletic gloves
- Industrial work gloves
- Apparel
- Bag handles and straps
- Mated athletic glove-handle bar applications
- Mated work glove-equipment applications
Can be sewn to a wide variety of substrates
Here's a Grip Tip
If needed, plain backed 3M™ Gripping Materials can be bonded in place prior to sewing to prevent movement during the sewing process. Pressure sensitive adhesives, such as 3M™ Adhesive Transfer Tape 6035PC or 6038PC, work well for temporary holding of the material. Plain-backed 3M™ Gripping Material products can be shear cut, die-cut, laser cut or converted by other applicable methods, and can be sewn to a wide variety of substrates using most commercially available equipment. Additional information on sewing techniques can be found on applicable 3M Plain Backed data page.
Performance in a Wide Range of Temperatures
3M™ Gripping Material GM640 performs well across a broad range of temperatures, ranging from -40°F to 140°F (-40°C to 60°C) indoors and outdoors.
About 3M™ Gripping Materials
3M's gripping materials are available in roll or sheet form in a wide range of tactility from very soft to firm. Soft gripping material products are designed to be more comfortable during skin contact and tend to be more flexible to contour more easily to tighter curves. Firm gripping material products are extremely durable, and tend to be stiffer. If prolonged service life in harsh use conditions is a critical feature for your product, durability of the gripping material increases with firmness. Actual service life will depend on frequency of use and severity of end use conditions, but typically, most 3M™ Gripping Material can outlast leather in a factory or in the field. 3M™ Gripping Material products are designed to be used alone, or as a two-part mated system. When used alone (on a single surface), the 3M™ Gripping Materials provide a strong secure grip. When used as a two-part mated system, for example, on a glove and handle bar, grip strength is maximized.
