The Right Elastomer Starts With Your Process
Quality rollers begin at the source — raw materials. Our compounding plant formulates each cover using strict quality control and precise technical and chemical knowledge of every elastomer.
Nine conditions drive every selection.

A combination of strict quality control, current mixing technology and detailed chemical knowledge of each elastomer goes into formulating compounds that operate at peak efficiency. Every roller is tested against exacting standards — the result is reduced downtime, lower maintenance costs and better process efficiency.
Fourteen families, compared.
Typical strengths are shown below to guide first selection. Exact hardness ranges, temperature limits and chemical compatibility are confirmed per compound and application with our technical team.
