Rubber Compounds and Applications


Most vacuum pads are available in various rubber compounds for different applications.

Please contact us or your authorized dealer for help selecting the best rubber for you.

Rubber Compounds Comparison Chart

55natduropoly Standard 1) Standard rubber is our most widely used compound, with superior performance in a variety of environments. This compound also features excellent abrasion resistance.
(Not recommended for contact with oily surfaces.)
40duronat Low-Marking 2) Low-marking rubber avoids leaving marks or stains on light-colored materials. This low-marking compound is recommended for indoor applications, such as production lines.
(see low-marking/UV-resistant compound for outdoor use). This compound also excels in resisting abrasion.
60duronitrile Oil-Resistant 3) Oil-resistant rubber resists damage from petroleum-based oils, like those commonly found on sheet and plate metals. This compound also features superior abrasion resistance.
60durosilicone Heat-Resistant 4) Heat-resistant rubber is ideal for removing glass from tempering ovens. However, they have about half the lifting capacity compared to standard rubber.
52duroEPDM UV-Resistant 5) UV-resistant rubber is ideal for extended use outdoors.Commonly used on windshields or in similar outdoor settings.
40_duronat Medium-Flexible 6) Standard medium-flexible rubber provides flexibility, allowing vacuum pads to attach to textured surfaces, such as pattern glass.
55duropoly Coating-Compatible 7) Coating-compatible rubber is designed to handle low-E glass and other coated materials without leaving markings. It's also good for handling painted and silk-screened glass.
52durepdm Low-Marking,

8) Low-marking/UV-resistant rubber avoids leaving marks and also stands up to extended outdoor use. Ideal for light colored materials.
49478T_100 Low-Marking,

9) Low-marking/medium flexible rubber avoids leaving marks on lighter materials, while also providing flexibility, allowing vacuum pads to attach to textured surfaces, such as pattern glass, as well as thin materials.
