Description

T-Global TG-A3500 is a high-performance thermal gap filler pad designed to provide efficient heat transfer between electronic components and heatsinks or enclosures. With a thermal conductivity of 3.5W/m-K, TG-A3500 ensures reliable thermal management across a wide range of applications, from power electronics to consumer devices.

This soft, compliant, and silicone-based gap filler is ideal for filling uneven surfaces and maintaining thermal contact without excessive pressure. TG-A3500 combines excellent thermal conductivity, mechanical compliance, and long-term reliability, making it a preferred solution for engineers seeking to improve heat dissipation in compact or irregular assemblies.

Optimised for performance, compliance, and ease of use, TG-A3500 thermal interface pads are used globally n industries such as automotive, telecommunications, and industrial electronics.

I have been searching for a company to help me out with a complex heat transfer material and I cannot recommend Materials Direct enough.

⭐☆☆☆☆

I am beyond disappointed with the lack of transparency and poor service from Materials Direct. I placed an order in October 2024 and only received two of the smaller items. The rest were refunded, yet I was still charged more than the original delivery cost of £77.50 – even though the larger items justifying that cost were not delivered. Shockingly, the delivery charge was greater than the value of the items I actually received.

There is a complete lack of clear terms and conditions addressing delivery charges in cases of partial fulfillment, which leaves customers like me paying excessive fees with no justification. This experience was frustrating and inconvenient, and I expected far better service and transparency from a company of this scale. Materials Direct needs to review its policies and ensure customers aren’t unfairly charged in cases where orders are not fully delivered.
