The Elastomer Chart below is intended to help in the material selection stage of designing rubber components. Rubber compounding is a broad and technical field since rubbers and elastomers are mixed with various chemicals or with each other to achieve the required physical properties.
A wide variety of polymers are available and an infinite array of compounds exhibiting unique physical properties as well as chemical, fluid and temperature resistances. This chart deals with the general characteristics of basic common rubber or elastomer compounds. These properties can vary to some extent depending on specific additives for modification. Our engineers can help you select the best compound for your specific application. We can also identify the compound and durometer of your present part for duplication.
Plain Face - Plain ground texture or smooth finish used for a multitude of purposes.
Chevron Pattern - Good pulling action, helps keep conveyor belts tracking properly, smoothes out wrinkles in continuous webs.
Herringbone Pattern - Used as a web spreader or feed roller.
Spiral Pattern - Proper combinations of groove angles along with land and groove widths enhance the grinding or sanding ability of wide coated abrasive belt machines.
Step & Plunge - Effective at aligning substrates or allowing material to pass between rollers without being crushed.
Ruling Pattern - Fluted rollers are used for spreading thicker adhesives and handling rigid or heavy stock, conveyor belt drives or scraping unwanted materials from substrate.
Spreader Pattern - Used to remove wrinkles, widen webs and to seperate slits.
Diamond Pattern - Minimizes hydroplaning and provides better gripping for feed rolls and channeling air or liquids away from substrates.
