Thermal management is one of those hidden but absolutely critical challenges in electronics design. As devices get more powerful and compact, heat has fewer places to go. Without the right thermal interface material (TIM), systems risk overheating, performance throttling, or outright failure. That’s where TGP 2000, part of Henkel’s Bergquist line, steps in.
What Makes TGP 2000 Different
TGP 2000, sometimes listed as Gap Pad 2000S40 or GP2000S40, is a fiberglass-reinforced, silicone-based thermal pad designed to combine softness and conformability with mechanical durability. It’s sold in standard 8″ × 16″ sheets, with custom die-cut parts available through converters like NEDC.
Depending on the source, you may see it called:
-
TGP 2000 (formal Bergquist naming)
-
Gap Pad 2000S40
-
GP2000S40
-
Occasionally just “2000S40”
Key Performance Metrics
-
Thermal Conductivity: 2.0 W/m·K
-
Dielectric Breakdown Voltage: >5,000 VAC
-
Volume Resistivity: ~1×10¹¹ Ω·m
-
Flame Rating: UL 94 V-0 (self-extinguishing)
-
Operating Temperature Range: –60 °C to 200 °C (–76 °F to 392 °F)
-
Hardness: Very soft for excellent surface conformity, reinforced with fiberglass for shear and tear resistance
-
Natural Tack: On both sides for easy assembly without adhesives
Availability: TGP 2000 is offered in a variety of thicknesses, typically ranging from 0.020″ (0.5 mm) to 0.125″ (3.2 mm). Full sheets can be purchased, or NEDC can provide custom die-cut parts tailored to the exact application.
Case Study: Solving Heat in a Telecom Module
One telecom equipment manufacturer was struggling with a recurring issue in their rack-mounted base station modules. Each unit used a bank of DC/DC converters to manage power distribution. Under heavy loads, these converters generated heat that was leading to premature throttling, occasional shutdowns, and, ultimately, costly warranty returns.
Their original design relied on a standard thermal grease solution between the converters and the shared aluminum heat spreader. While inexpensive, the grease was messy, inconsistent in thickness, and degraded during thermal cycling. Service technicians hated working with it, and customers were seeing variability in field performance.
That’s when they approached NEDC, an approved Bergquist converter, for help.
NEDC evaluated the thermal stack-up and recommended a switch to TGP 2000 (Gap Pad 2000S40), custom die-cut to fit the converter layout. Because NEDC is authorized to convert Bergquist materials, they were able to produce exact-fit pads that dropped directly into the existing assembly line without redesigning the chassis.
Results
-
Improved thermal stability: Operating temperatures dropped by nearly 12 °C compared to grease, eliminating thermal throttling under peak loads.
-
Cleaner assembly: Line workers reported a 30% reduction in assembly time thanks to the pre-cut, tacky pads that required no spreading or curing.
-
Field reliability: Warranty returns due to overheating dropped by 80% within the first year of rollout.
-
Customer perception: End-users noticed quieter operation, since cooling fans no longer ramped as aggressively.
The engineering team later noted that the switch didn’t just solve a problem—it opened the door for them to push more power through the same form factor in their next-gen modules.
Why Work with NEDC
For companies facing similar challenges, the partnership matters as much as the material. NEDC’s status as an approved Bergquist converter ensures that every piece of TGP 2000 (Gap Pad 2000S40) they ship is genuine, properly handled, and tailored to the customer’s exact geometry. Whether it’s small prototype runs or full production volumes, NEDC provides the precision cutting and quality assurance that high-reliability industries demand.
