CASE STUDY

ML6 Polyurethane Matte Finish Rollers Drive Thin Rolls of Plastic Films

Challenge

Polyurethane rollers were being used in the packaging industry to drive thin rolls of plastic films. In this case, the thinnest plastic films were found to cling to the surface of any roller, rather than release while being driven as desired. This application demanded a high coefficient of friction with low ‘tackiness’. The customer tried multiple different rollers, also cleaning rollers with MEK and with soap & water, none of which helped enough to solve this issue.

(Competitor roller with ‘tackiness’ problem unable to deliver the high coefficient of friction needed, leading to a solution that only ML6 precision polyurethane could provide.)


Solution

Meridian Laboratory leaned on our engineering expertise and high-performance testing to specifically develop ML6 polyurethane matte finish rollers (still unground and featuring ML6 industry-leading tolerances). The end solution is one which provides the same tolerances and durability which Meridian Laboratory ML6 precision polyurethane is known for, but now features a non-stick surface for passing materials.

(Top two ML6 rollers feature the new matte finish, compared to the bottom two standard smooth high friction ML6 rollers.)


Product Details

Standard ML6 Precision Polyurethane products feature an unground, cast to size, surface finish – allowing for the maximum amount of contact surface between roller surface and material being driven. This smooth, unbroken surface is similar in concept to a racing slick tire on a drag race, providing maximum friction. ML6 also features increased longevity over typical ground rollers, because the outer skin of Meridian Laboratory rollers are left intact. There are applications, like this one, where the perfectly smooth finish is not optimum.

After rigorous testing and prototyping, Meridian Laboratory found that a different surface finish would be required to drive the material successfully, without increasing the hardness of the durometer. This called for a precise Matte Finish. The outer surface of the ML6 rollers was cast to be rougher than our standard rollers to allow for less friction, and to increase the release properties between the rollers and the driven material. All of this was achieved without changing the hardness of the polyurethane. This rougher finish uses the same precision casting process as all other ML6 products, the surface of the parts are not ground or machined in any way. This provides for the same long-lasting service life of the part, with a surface that is ideal to the application.


Constant Improvement

Meridian Laboratory has embraced challenges since 1963, and we always look forward to providing all of our great customers with the best possible solutions. Matte finishes can be made available for all durometers and in the majority of sizes that we produce.

    I ordered a drive roller for my high precision telescope tracking mount. A fantastic product that works perfectly. Vance … More was really helpful getting the product out to me. Great service and highly recommended.

    I purchased some hubbed rollers for a personal project I am working on. The sales team was VERY helpful and provided me with … More a sample kit which guided me to the right roller for my application. The rollers I received were really good quality and worked perfectly for what I needed. Would definitely recommend if you need polyurethane rollers for any projects.

    Worked with Vance on getting some rollers for an application of ours. He is very knowledgeable and was able to get the rollers … More for my company in a timely manner. Had an issue with one of the rollers and he replaced it for free! I am sure they took that roller apart and studied why it was rolling "rough". I really appreciate the time, the quick response, and how things were handled. Thank you Vance!
