Which is the right rubber for my roller?
Call us and let’s talk!
Many factors must be considered before using a rubber part in service. The most important as we see them are:
The Temperature of Service
Higher temperatures increase the effect of all chemicals on polymers. The increase varies with the polymer and the chemical. A compound quite suitable at room temperature may fail miserably at elevated temperatures.
Conditions of Service
A compound that swells badly might still function well as a static seal, yet fail in any dynamic application.
The Grade of the Polymer
Many types of polymers are available in different grades that vary greatly in chemical resistance.
The Compound Itself
Compounds designed for other outstanding properties may be poorer in performance in a chemical than one designed especially for fluid resistance.
The Durometer
In general, the harder a compound the better its resistance. [Click here for more Information!] Not cleaning rubber rollers properly affect your production quality and the roller’s life!
NOT all coatings resist to any cleaning solution! Some are sensitive against alcohol, others get destroyed by solvents.
Heptane is a good solution for all coatings.
Using Heptane to get the ink out of your press rollers proves difficult sometimes.
If this is your case, don’t hesitate to contact us and we will be more than glad to help you with any project. [Click here for more Information!] Generally it doesn't. [Click here for more Information!] The surface finish varies a lot with the type of coating and hardness.

A rule of thumb: Hardness increases abrasion resistance.
Keep in mind that there are many other characteristics involved in the definition of a unique coating! [Click here for more Information!] Standard lead time is 2-3 weeks for roller recovering.
For new rollers including cores it might go up to 4 to 5 weeks.
If we can, we make exceptions for rush orders for no charge.
We also offer the option of delivery and/or pickup where applicable.
You are also more than welcome to come by to deliver. [Click here for more Information!] Depending on size and weight, our customers use UPS/FedEx or their Trucking company. We ask you for instructions for shipping the rollers back.
We also offer the option of delivery and/or pickup where applicable.
You are more than welcome to come by to deliver and to pick-up. [Click here for more Information!] Avoid this critical situation and have spare rollers! You avoid delays and a stop in the production process.
Ordering ahead of time ensures that we make sure we get our raw material on time in order to decrease our lead-time for you.
Standard lead time is 2-3 weeks for roller recovering and 4 to 5 weeks for complete new rollers.
If we can, we make exceptions for rush orders for no charge. [Click here for more Information!] Avoid rubber rollers to stay in direct contact with the floor, shelf or table to prevent flat spots.
Keep the rollers covered at all times to prevent environmental contamination.
Our team at Alrol has been trained to take care of the rollers that are manufactured in our facility. Rollers need special care in order to work in an efficient way. Rollers that are confected by Alrol of America are stored in a designated area away from airborne contaminants, sunlight, free of humidity or extreme temperatures. We also make sure that the rollers are not stored in the same position for long periods of time to avoid flat spots and marks.
One thing to take into consideration is the fact that the longer the roller, the less damage can occur due to changes in temperature. Conversely; the smaller the roller is, the higher the possibility of roller damage. The ideal temperature to store your rollers is between 60 and 90 degrees F.
