Uncured EPDM Tapes vs. Cured EPDM Tapes (In-Depth Examination)

EPDM is an abbreviation of Ethylene Propylene Diene Monomer, a synthetic rubber type with many uses. This membrane is helpful to work as a sealant for multiple objects, mainly metal and rubber.

This sealant refrains heat and water from entering the desired thing. Cured vs. uncured EPDM tape options are under discussion in this article, but EDPM also has other varieties of tapes and membranes.

Cured EPDM tapes are best used as a sealant on metals, while uncured are known best for rubber objects. The shelf life of these tapes is around nine months, but their work is durable and lasts many years.

This article will illustrate the detailed analysis of both tapes, including the meaning, features, and critical comparative analysis.

Stay tuned to this article to learn more about the exceptional and exciting parts of cured and uncured EPDM tapes.

Cured vs. Uncured EPDM Tape

This article illustrates the critical analysis of cured vs. uncured EPDM tape, which is necessary to understand both tapes before selecting an appropriate option.

Fixed EPDM tape is one of the best sealants for metal objects as it has the strength to let it remain sticky on metal objects for more extended and work as an air-tight sealant.

Likewise, uncured EPDM tape works best on rubber objects. It is used for T-joint patches primarily because of its exceptional sealant features, which refrain heat and water from entering the area over which it has become a seal.

Moreover, both tapes are available in the market in black color only, but the cured video has many size options, but the uncured tape is limited to just one size option. 

In contrast, for installation, tape primer or lap sealant is required for cured EPDM tape, and splice adhesive is needed for uncured EPDM tape.

What Is Meant By Cured EPDM Tape?

Cured epdm tape is one of the valuable tapes required to finish the field membrane.

The material involved in making cured EPDM tape is 60 mils non-reinforced membrane, one of the standard sheeting.

The cured epdm tape mostly does metal edging due to its features, which seem best for metal rather than rubber edging.

Moreover, this tape has a thickness of 90 mils, which is very recommended for heaving sealing or edgings, and this tape can work as the best seal as well.

Features Of Cured EPDM Tape

Cured epdm tape contains multiple features, which makes it a distinct and more reliable tape when compared to uncured epdm tape. The following are the exceptional features of the cured epdm tape;

• Multiple size options are available, and this tape is not limited to just one size.
• Commonly used for the edging of the metal, to strip in seams, and for membrane repair as well
• It has non-reinforced epdm of 60 MIL and 90 MIL when totaled
• Cured epdm tape is available in just one color, and that is black
• Lap sealant and tape primer are required for the installation of this tape
• The area where cured epdm is to be used should be in the flat as this tape does not work correctly in the flat to the vertical direction

What Is Meant By Uncured EPDM Tape?

Uncured Epdm tape is instrumental when irregular shapes need to be shaped properly and regularly.

This tape is known for not reverting to the object’s original form but still manages to change the angle and conditions of the things according to users’ demands.

Manufacturing processes are complex and include many steps, one of which is the exposure of the roof to heat, which should be restricted so that products may not get affected by the heat directly.

To stop this, uncured epdm tape is used as it properly seals out all the roof edges and does not allow heat to affect the product directly. Moreover, uncured epdm tape has a life of nine months.

Features of Uncured EPDM Tape

Uncured Epdm tape includes multiple features, which are listed below;

• It is best to be used as a seal of flashing for pipes, corners, etc
• Uncured Epdm Tape does not mold the original shape of the object, due to which it is mainly preferred to be used
• Mainly used as a sealing and t-joint patches
• Uncured tape is only available in 60 MIL thickness
• This tape is 12 inches wider and 100 inches longer
• This tape is also only available in black color
• Uncured epdm tape does not have many options like cured epdm tape as it has just one size available.
• Splice adhesive is required for the installation of this tape
• MOD bit and tie-ins on BUR use this tape mostly

Cured vs. Uncured

The main features of cured and uncured epdm tape have been discussed earlier in this article.

However, a precise cured vs. uncured EPDM tape analysis is required better to understand the similarities and differences between both tapes.

• The uncured tape has 60 MIL thickness, while the cured tape has 60 MIL non-reinforced thickness when the total becomes 90 MIL.
• Both of the tapes are only available in the market in Black color
• Cured tape has multiple size options to choose from, while uncured epdm tape comes in one size
• Cured tape should be applied with lap sealant and tape primer, while for uncured tape, a splice adhesive is required
• Cured tape is best to be used on metals, while uncured tape is best to be used on rubbers
• Cured tape is used as the edging of the metals, while uncured epdm tape is best used as t-joint patches

Conclusion

The cured vs. Uncured epdm tape article is about the definition, features, and comparative analysis of both epdm tapes. 

A conclusion is drawn based on the above discussion: both tapes have distinct features that can not overlap, as one is the best sealant for metal objects while the other is best used on rubber objects.

Simultaneously, both are only available in black color, with cured having multiple size options and uncured with just one size option.

Both epdm tapes are suitable to be used on their prescribed objects and are not substitutes for each other.

Moreover, to use cured EPDM tape, tape primer or lap sealant is required, while uncured epdm tape requires only splice adhesive.
