Statement on the End of Life Status for TGX, TG2030, TG4040, and TG6050 from T-Global Technology

It has come to our attention that a company that has no connection whatsoever with T-Global Technology are claiming we will no longer be supporting the TG series and that they are in fact the manufacturer of these products. Both of these statements are false. Products manufactured by T-Global Technology are only available through our approved distributor, Digi-Key, or directly through ourselves.

T-Global Technology’s new TG-A series range of silicone thermal pads is the next generation of thermal interface materials utilising the latest technology and processes. These pads offer superior performance at a reduced cost and supercede the TG series of thermal pads.

For this reason, T-Global Technology has decided to End of Life the TG series products in our distributor Digi-Key Electronics to promote the use of the TG-A series for new projects. The last buy date for TGX, TG2030, TG4040 and TG6050 silicone thermal pads through Digi-Key will be the 31st of December 2020. You may find a list of the affected Digi-Key parts and the recommended replacements here (Links open in new windows): TGX, TG2030, TG4040, and TG6050.

T-Global Technology will continue to support the TG series products beyond the end of 2020 for specific applications and existing projects. However, we encourage customers to sample and approve the new TG-A materials wherever possible.

We believe that innovation and product development are key to remaining relevant in the fast-moving technology sector. It is for these reasons that we develop and bring new products to market to support the growing demands of ever-increasing power densities.

For any further information regarding the end of life of TGX, TG2030, TG4040 and TG6050 or you have any concerns about the parts that you currently purchase from us, please contact us at sales@tglobaltechnology.com.

We thank you for your past business with us. We look forward to supporting you in 2020 and beyond.

What is Hardness anyway?

When selecting a material based on hardness for thermal management, it is important to understand and appreciate the differences in these scales so that a material with the desired properties is selected.

Hardness is a physical property of a material and is defined as its resistance to indentation. It is typically used to quantify the hardness of polymers and elastomers and is an important factor in the performance of thermal interface materials.

Named after Albert Ferdinand Shore, the Shore hardness scales are an industry standard for measuring hardness of materials that vary all the way from gel like materials, up to hard plastics and rubbers. Since there is so much variation in the hardness of polymers and elastomers, there are different scales on which hardness is quantified.

The resistance to indentation (hardness) is measured by applying a known force onto the material using an indenter of specific geometry and measuring the resulting depth of penetration. The geometry of the indenter and the force applied are two of the test variables that are changed that give rise to the different Shore hardness scales.

Amongst the many Shore hardness scales are Shore OO and Shore A, primarily used for softer materials. These are the most common in the field of thermal management since soft materials carry with them several advantages over harder materials. However, the Shore OO and A scales use a different methodology. Therefore, they are not directly comparable. Although not directly comparable, it is common practice to use a basic table such as the one below to estimate the hardness across different scales.

All Shore hardness scales range from 0-100, the lower the number, the softer the material on the given scale.
