As a global leader in silicone technology, Dow exhibited high-performance thermal management solutions and innovative materials for EMI (electromagnetic shielding) and 5G networks at the Munich Electronics Show.
Competing for a new 5G track, how can Dow run and accelerate? To this end, New Materials Online® interviewed Rogier Reinders, director of global marketing for circuit boards and systems assembly at the Dow Consumer Products Solutions business unit, to explore Dow's innovations in the 5G and electronics industries.

Interview with New Materials Online®
Fighting for 5G heat dissipation and EMI "two-pronged approach"
Between the vicissitudes of life, the square inch is full. Dow disassembled a smart phone on the spot, showing in detail the thermal solution and EMI innovative materials of Dow.
"Among Dow's more than a hundred thermal solutions, the new Dow ™ TC-3015 silicone thermal gel is one of our star products." Rogier Reinders told New Materials Online®: "The silicone thermal gel After curing, a thermally conductive gel is formed, which enables efficient heat dissipation of the chipset. "
Heat dissipation is a problem that must be overcome for the normal operation of mobile phones. Thermally conductive materials are also one of the key materials upstream of the 5G industry chain. In the 5G wave, thermal materials will usher in incremental demand, and the market size is expected to open up new space.
This is supported by forecast data from BCC Research. Data show that the global market size of thermal interface materials will increase from US $ 800 million in 2015 to US $ 1.1 billion in 2020, with a compound growth rate of over 7%.
In order to meet the higher requirements for heat dissipation performance in the 5G era, Rogier Reinders revealed that Dow's high-performance silicones will continue to innovate and comprehensively improve the performance of thermally conductive products, such as the current thermal conductivity of Dow ™ TC-3015 thermally conductive gel. From 2W to more than 8W.
“Tao Xi ™ TC-3015 Thermal Gel also improves the productivity and performance of high-performance processing and control components.” Rogier Reinders added that this outstanding thermal material simplifies the processing of smartphones and other components during rework. It can be easily and completely peeled off without leaving any residue.
Taoxi ™ TC-3015 Silicone Thermally Conductive Gel can also be integrated into the production automation process by automated dispensing, eliminating the need to spend too much time on the finished thermal pad and avoiding the inefficiency caused by manual operation.
In the 5G era, in addition to increasing heat dissipation challenges for smart devices, the demand for electromagnetic shielding materials is also increasing.
With the advent of 5G, the introduction of high frequencies, the upgrade of hardware components, and the doubling of the number of connected devices and antennas have made electromagnetic interference everywhere between devices and within the device itself. The hazards of electronic equipment are also becoming increasingly serious, and the role of electromagnetic shielding materials is becoming increasingly apparent.
The Dow Company knows what is going on and is following the trend, and at this exhibition announced that it has entered the electromagnetic shielding market.
"With the rapid development of 5G networks, mobile technologies, and connected devices in transportation and other fields, we continue to strive to provide our customers with the advanced materials they need to help them win the market," said David Chen, Dow ’s Consumer Product Solutions Greater China Business Manager. . Dow's entry into the electromagnetic shielding (EMI) market with silicone conductive materials and its new generation of advanced silicon technologies continues to demonstrate our unwavering commitment to related fields, customers and the electronics industry. "
Competing for 5G, electromagnetic shielding material manufacturers have started the battle, why is the Dow company winning?
Rogier Reinders tells New Materials Online® that although there are many electromagnetic shielding material solutions on the market, due to the higher material requirements for 5G, Dow will rely on cutting-edge silicone technology to provide hundreds of thousands of solutions that can Meet the needs of equipment for electromagnetic shielding materials in different scenarios.
Of course, 5G is a profound change in the mobile communications industry. The challenge for equipment is not only the increasing demand for heat dissipation and electromagnetic shielding, but structural changes have also increased the challenge of electromagnetic pollution.
In the electronics industry, protection against electromagnetic pollution is a growing concern for designers of printed circuit board (PCB) structures and components. As 5G networks increase data transmission volumes and rates, smaller components, higher-density packages, and more and more equipment connections are increasing the risk of electromagnetic pollution.
Rogier Reinders said Dow's advanced and innovative solutions can help designers overcome these obstacles and solve other challenges.
Targeting new energy vehicles
The 2019 Munich Shanghai Electronics Fair is one of the important electronic exhibitions in Asia. This exhibition comprehensively displays the key links of the electronics industry chain, presents advanced technology of electronic products through an innovative perspective, and completely explains the future development trend of the electronic application field.
At the Dow show, "Muscle Show", in addition to highlighting new material solutions to cope with the 5G wave, it also launched three new silicon-based materials for the electronics and lighting industries, including Taoxi ™ EA-4700 CV adhesive, Taoxi ™ EG-4100 dielectric gel and Taoxi ™ EI-2888 primerless silicone sealant.
On a smart car light disassembled on the spot by Dow, you can directly see the bonding effect of Taoxi ™ EA-4700 CV adhesive.
With the development of new energy vehicles and autonomous vehicles, engineers around the world are looking for a new generation of silicone solutions for automotive assembly, hoping to improve battery packs, radars, and lidars while meeting safety and reliability requirements. Production efficiency of advanced driver assistance system (ADAS) sensor modules such as cameras and cameras.
Dow Wang, Marketing Manager, Consumer Product Solutions, tells New Materials Online® that Taoxi ™ EA-4700 CV Adhesive can provide durable bonding and environmental sealing for substrates used in automotive electronic modules such as aluminum, PBT, and PPS. More importantly, this silicone adhesive can be quickly cured at room temperature, thereby improving the mass production efficiency of electronic packaging and reducing energy consumption.
Relying on new chemistry and formulation technology, the new Taoxi ™ EA-4700 CV adhesive can achieve a bonding strength of 1 MPa in 3 hours when cured at room temperature. "At a temperature of 80 ° C that most plastic substrates can withstand, this adhesive can form a bond strength of 1 MPa on the surface of the PBT substrate in less than 5 minutes," Wang added.
Innovation has always been the genes of Dow. It is good at predicting the development trend of the industry in advance and solving the pain points and difficulties of the industry.
The introduction of Taoxi ™ EI-2888 primerless silicone sealant is to solve the problem that LED lamps used in harsh environments need reliable, easy-to-apply, and highly curing protective materials.
Konstantin Sobolev, Dow's Strategic Marketing Manager, said, "Taoxi ™ EI-2888 Primerless Silicone Sealant avoids time-consuming processing steps and reduces the potential for curing performance to be impaired by surface contaminants or moisture. The waste of this low-viscosity silicone sealant can be easily dispersed and firmly adhered without sacrificing optical performance. It can be excellently used in areas such as explosion-proof lighting, outdoor displays, and flexible and rigid LED light bars. "
