A Fresh Look at Butterfly Tenergy 05 Rubber

This is the first article to be written under the Tenergy 05 review heading. I have been thinking with all the study of the rubber I am going to create an examination on it. Before you sit the test we need to look at the differences between criticism, a critique and a review.

Although this all seems very abstract, a simple blurb comment will not be enough. I am impressed by the level of discourse I have read from Pnatchwey and Thaidog. The discussion or inspection goes beyond judgment, and is more like a thesis.

Tenergy 05 durability

Tenergy 05 durability is a much asked about topic by players considering buying their first sheet. The sturdiness over time that Tenergy shows means that it holds its backbone with constancy. The durability means although it is a more expensive rubber, the endurance will give you the full grit or gutsiness for longer and make it worth it. It may not be hard as nails, but its lastingness means you can rely on its staying power as a spinning table tennis rubber. The durability of old generation rubbers is better but the amount of spin they can create straight out the packet is equal to what Tenergy can after a year of use.

A fresh look at Tenergy 05 confusion?

My friend Boz asked me recently to write a fresh review about Tenergy 05 specifically. I really wondered exactly what I can say about this rubber that hasn’t already been said. Especially because he said he wanted to create a new very clear category that doesn’t focus on all the Tenergy family. He said it must be very, very clear: “could you write a clear new categorical heading that will specifically target Tenergy 05 and not the other spring sponge versions out by Butterfly?”

Mmmmm, only about Tenergy 05, how can that be possible? Almost everything I have read refers to Tenergy 25, 64, FX, or other rubbers. So I thought I have to do my research to be able to tackle this huge task. With my good old tool: Google search I wanted to see what has been said. I thought I might just document my search of what has been said to try to find what will be able to be said. Does that make sense?

Physical qualities seem contradictory?

What I would like to say is that all the information about Tenergy 05 can be confusing and contradictory when looking at what real reviewers have to say. For example, when talking about speed glue. Others, such as you can see in the Varghese and Greg Letts articles, still refer to it in the old “built-in speed glue rubbers” category which I don’t quite understand the relevance of any more.

Density feeling

The density of the rubber is 36 degrees according to the Butterfly hardness scale, but it feels harder or more solid than most Euro rubbers. To push it with your fingers, you will find that it feels medium hard, but when playing with it many players find it unusually soft in the way it holds the ball.


Warning are everywhere. I found somewhere that Tenergy 05 has a medium reglue effect. Not sure who the hell would want to speed glue it. And then right after finding that I found the opposite advice: You shouldn’t use speed glue with this rubber. It is really for water glue..

Others warn that this rubber might be too fast and have too high a throw angle. The consensus is that:

Tenergy 05 is fast enough

It is slower than the high speed rubbers out there but after a lot of research I found that most reviewers of Tenergy 05 said that it is fast enough and because of the highest spin they have found that it’s speed is the easiest to control. The ratio of speed to spin is in the perfect balance. Most importantly it has enough speed from away from the table too.

Confusion on how easy it is to use or control Tenergy 05 is everywhere

Numerous forum posts tell lower level players to never use such a hot rubber and then others say this rubber is an extremely forgiving rubber when going for a winner above the table. Blocking is also amazing and it blocks will almost automatically be aggressive due to the catapult effect.

I am not allowed to write about the high tension, but in reality the word high tension is a point often mentioned in relation to tensors. this is another confusing point about the rubber:

Tenergy 05’s” High Tension” technology is more effective than “tensor” technology because of the hardness of the topsheet.

The rubber is widely believed to be a Tensor rubber, which many people disagree about. For me personally it really comes down to names and what those names represent. There are a great number of Butterfly table tennis rubbers that has the label or badge saying “High Tension” technology on them. Tenergy 05 has this symbol. On the other side of the world the German ESN rubber factory produces about a hundred different rubbers with a very similar logo – but they call it “Tensor”. The meaning of Tensor or high tension is the same thing, but the manufacturers ability to create the a rubber which has a tense or intense catapult is different. Without a doubt most people would say that Japanese rubber is much harder and more durable, so the tension is highest in Butterfly easily. Esn rubbers are to put it simply, too soft to give true tension.

On one hand, you have reviews saying it takes time to adjust and on the other, Tenergy is the rubber loopers realise immediately, they have been looking for.
