Pro vs. Max vs. Ultra: Understanding Our Rubber Sheet Grades

Are you browsing through our rubber sheet catalog and came across ‘Pro’, ‘Max’, or ‘Ultra’ written beside the product’s name? Why do some products like our Silicone sheet roll come in the Pro version only, and not in any other types?
Well, at Duratuf, the ‘Pro’, ‘Max’, and ‘Ultra’ are not just random tags. Instead, they convey the most critical information that you, as a buyer, should know.

Whether you are buying a Silicone gasket sheet material or high tear strength Silicone sheet, these tags must be confusing for you. Moreover, you might have never come across just name tags.

‘Pro, ‘Max, ‘ and ‘Ultra’ at Duratuf define the performance tier of the product. While most of our rubber sheet types are available in various performance ranges, some products, like the Silicone sheet roll, only come in one type.
If you want to know ‘Why’, then you must quickly find your answer in this blog. Along with the answer, you will also get to know what each tier means and what changes between them.

What are the Various Performance Tiers that the Silicone Sheet Roll does not have?

Duratuf EPDM, NBR (Nitrile), and Chloroprene (Neoprene) are divided into the PR, Ultra, and Max categories, while our Silicone sheet gasket material does not. This is how we define our performance tiers:

• The Pro tier is the standard high-performance option in our most rubber sheet ranges. Nevertheless, it is not our starting range. We also have an ‘economic Lite’ version of many rubber sheets, like the natural rubber sheets.

The Pro offers balanced durability, flexibility, and resistance to a set of environmental factors. Thus, it is suitable for a wide range of industrial applications without the extra cost of premium upgrades. Our Silicone sheet roll comes only in the Pro version.

• The Max tier is an upgraded version of the Pro tier. It has improved tensile strength, abrasion resistance, and in some cases, extended temperature range. These sheets are designed for more demanding work environments. A demanding work environment means applications where the material will be under heavier mechanical or environmental stress.
• The Ultra tier represents our most premium grade. It is designed for extreme work conditions.

Ultra rubber sheets are built to withstand the harshest industrial settings. It has maximum polymer content and fewer fillers. The fillers like carbon black, Zinc oxide, etc, are used to make colored rubber sheets.
The Ultra rubber sheets offer superior resistance to chemicals, have very high tensile strength, and the longest possible service life. They often comply with additional industry-specific certifications, making them the choice for mission-critical operations.

How do the Pro, Ultra, and Max Rubber sheets apply to real-world applications?

The reason behind categorizing our rubber sheets into Pro, Ultra, and Max was to highlight their superiority. But how do we, as one of the leading rubber product suppliers, define durability? Below are the factors that we consider:

• Temperature Tolerance – Our Ultra versions of rubber sheets can tolerate a wide temperature range, followed by Max. The Pro range covers the essential range for most industrial needs.

It is true that our insulation Silicone sheet for ovens is only available in the Pro version, but it aligns with the industry-accepted Silicone sheet high temperature chart.

• Mechanical Durability – Ultra sheets have the strongest tear- and impact-resistance, with Max offering more durability than Pro in tough conditions.
• Chemical Resistance – Ultra rubber sheet grades provide the strongest resistance to aggressive chemicals. Thus, making them suitable for heavy-duty chemical processing environments.

Chemical resistance matters the most in industries like the oil and gas extraction plants. This is why we offer the most popular choice for such industries- the NBR or Nitrile sheet in Ultra versions.

• Compliance Standards – Pro versions meet standard compliance requirements, while Max and Ultra may be designed to meet stricter or multiple certifications for industries like aerospace or food processing.
• Service Life – Ultra sheets offer the maximum longevity; Max lasts longer than Pro. However, Pro is still a reliable option for standard use cases.

Hence, if you want to buy a Silicone sheet roll from us, do not think that it will not last long. There is a reason why we have kept our Silicone sheet in only the Pro variant, and that is-

Why Duratuf Silicone Sheet Roll is Available Only in Pro Version: Thought for the Buyers

Silicone sheets are always in high demand. In 2025, the demand has even increased.
Silicone gasket sheet material makes ideal leak-proof seals, gaskets, and O-rings in industrial applications where high temperatures are common. Insulation Silicone sheet for ovens is safe, non-toxic, and lasts long.

How does a buyer-focused approach shape our operations?

Duratuf offers Silicone sheet roll only in the Pro version because it is still economical and effective for the buyers. With the performance tags, the Max and Ultra versions get costlier. Our experts have found in multiple internal surveys and market research that most silicone sheet heat press buyers use them in moderately demanding applications.
You must be thinking that buying a rubber with the most superior features will not harm. But why should you spend so much money when you have a great product at a lower price?
While the more the merrier, we want our buyers to spend money on what they require, actually require.
Even in its Pro form, silicone offers performance levels that can match or exceed Max and Ultra grades of many other rubber types because of its features, which are:

• Superior Temperature Range: Our Silicone Pro sheets can handle -60°C to +230°C without compromising their shape or elasticity.
• Ozone and UV Resistance: Our high tear strength silicone sheet does not deform near Ozone or UV rays.
• Non-Reactive: Our Silicone sheet roll is non-reactive. However, these are not FDA-compliant food-grade sheets. Browse through our food-grade compliant rubber sheets.
• Minor electrical Insulation: Silicone is a high-quality dielectric material, making it suitable for electrical insulation tasks. But if you are thinking about electrical safety, you must use electrical insulating rubber mats.

How will you choose the Right Rubber Sheet Type for your Application?

If you are not working with a Duratuf Silicone sheet roll, then the choice between Pro, Max, and Ultra depends on your operational conditions.

• Use Pro for general industrial tasks in standard industrial applications
• Choose Max when you need enhanced durability and performance in high-stress applications.
• Opt for Ultra in extreme conditions where equipment failure is not an option.

In Conclusion,

Duratuf has come across a new style of naming the rubber sheets, where we use tags like ‘Pro’, ‘Max’, and ‘Ultra’ to denote their performance tiers. However, some of our ranges, like the Silicone rubber sheet roll, come only in the Pro variant.
