Natural Insertion Rubber Sheet is an economical form of general purpose rubber. It is known by a number of names including Insertion Rubber, Natural Rubber Insertion and NRI. This type is made using natural rubber compound that is reinforced with one, or more (depending on the thickness) layers of cotton running through the middle. This means that rubber sheet has the sealing attributes you’re used to with natural rubber but added tensile strength because of the cotton.
Our Insertion Rubber Sheet can be cut using a Stanley knife or scissors (for the thinner types). It also has good resistance to mild acids and alkalis as well as ozone. This type of rubber is not suggested for sealing oils, petroleum or hydrocarbons (for more info on what the chemical resistance of insertion rubber, click here to see our rubber chemical page).
Instead, this rubber product it is usually used for things like wear pads, water seals or other uses that require a rubber with good abrasion resistance, controlled elongation and reliable performance at a low price point.

How to Buy Natural Rubber Insertion Online.
All of the rubber insertion featured on this page is quoted per lineal metre. To buy, select the thickness you require and adjust the quantity to the number of metres you need. Maximum roll length is 10 Metres and any order of less than this will be supplied in a single, continuous length. If you do have specific length requirements (e.g. 2 x 7 metres instead of 10 + 4) please do let us know and we'll do everything we can to assist.
If you're thinking about using rubber for sealing, it may well be worth checking the rubbers compatibility with the media first. To make this easy, we've put together a comprehensive guide that details the general chemical compatibility and resistance of 8 different types of rubber (including this one). You can view it right here.
How many layers of cotton are there?
This can vary depending on the manufacturer of the rubber. Here at Swift, we’ve standardised it to make things simple:
1.5mm & 3mm = 1 Ply of Cotton.
4.5mm, 6mm, 9mm & 12mm = 2 Ply of Cotton
Of course, we can arrange other constructions (e.g. 2 ply for 3mm thick) but everything listed here follows the specifications listed above.
If I order 5 metres, will you supply it in a continuous length of 5 metres or 5 x 1 metre pieces?
Generally, we’ll supply in one continuous length wherever possible. The only exception is when the length you have ordered exceeds the maximum roll length for that thickness of material. The maximum continuous length we can supply (as standard) is 10 metres (shorter for some of the thicker grades). Please contact us if you need lengths over 10 metres as we can arrange extra-long rolls.
