Chrometech Launches Industrial Robot Controller Thermal Adhesive

On May 6, 2026, Chrometech Industrial Co., Ltd. released a new high-frequency thermal conductive adhesive designed specifically for power modules in industrial robot controllers — marking the first commercial product verified under China’s newly implemented national standard GB/T 42818–2026. This development is of immediate relevance to manufacturers of industrial robots, thermal management components, and exporters targeting EU markets, as the standard has already become a referenced basis for the CE certification’s newly added thermal safety sub-criteria.

Event Overview

On May 6, 2026, Chrometech Industrial Co., Ltd. announced the launch of a novel thermal conductive adhesive engineered for industrial robot controller power modules. The material achieves a thermal conductivity of 8.5 W/m·K and passed the inaugural round of testing under GB/T 42818–2026, Test Methods for Thermal Management Performance of Industrial Robot Controllers. The standard officially entered into force on May 1, 2026.

Industries Affected by This Development

Industrial robot system integrators and OEMs: These firms may face revised thermal validation requirements during controller qualification or redesign cycles, especially where legacy thermal interface materials (TIMs) no longer meet the test protocols defined in GB/T 42818–2026. Impact manifests primarily in extended validation timelines and potential rework of thermal interface layouts.

Thermal interface material (TIM) suppliers and distributors: Suppliers must verify whether their existing TIM portfolios comply with the test methodology outlined in GB/T 42818–2026 — particularly regarding high-frequency transient heat dissipation performance. Impact centers on product documentation updates, third-party verification readiness, and technical support capacity for controller-specific thermal modeling.

Exporters to the EU market: As GB/T 42818–2026 is now cited as a reference for CE certification’s thermal safety sub-item, exporters must assess whether their controller-level thermal test reports align with the standard’s measurement procedures. Impact appears most acutely in technical file preparation and conformity assessment workflows with EU notified bodies.

What Relevant Enterprises or Practitioners Should Focus On — And How to Respond

Monitor official interpretations and application guidance from SAC/TC 159

The Standardization Administration of China (SAC) Technical Committee 159 (Industrial Robots) has not yet published implementation guidelines or test protocol clarifications for GB/T 42818–2026. Enterprises should track official announcements, especially those addressing test repeatability, sample preparation, and pass/fail criteria for high-frequency thermal cycling.

Review controller-level thermal test reports for alignment with GB/T 42818–2026’s scope and methodology

Current thermal test reports based on generic IEC or JIS standards may lack the specific dynamic loading profiles, sensor placement rules, or data sampling intervals required by GB/T 42818–2026. Firms should audit existing reports against the standard’s Clause 5 (Test Conditions) and Annex A (Measurement Procedure).

Distinguish between policy signal and enforceable requirement in export contexts

While GB/T 42818–2026 is referenced by EU CE certification authorities, it remains a national standard — not an EU harmonized standard. Its use in CE assessments is currently advisory, not mandatory. Enterprises should confirm with their notified body whether adherence is requested as evidence, or whether equivalent testing under EN 60068-2-xx series remains acceptable.

Assess supply chain readiness for TIM requalification and controller revalidation

Where Chrometech’s adhesive serves as a benchmark, alternative TIM suppliers may need to initiate parallel verification under GB/T 42818–2026. Integrators should proactively engage TIM vendors to determine lead times for test reports and availability of certified lots — particularly if controller production schedules extend beyond Q3 2026.

Editorial Perspective / Industry Observation

Observably, this event signals the formal institutionalization of high-frequency thermal performance as a distinct evaluation axis for industrial robot controllers — moving beyond steady-state metrics toward dynamic thermal behavior under real-world motion control loads. Analysis shows that GB/T 42818–2026 does not yet mandate specific material properties, but rather defines how thermal performance must be measured and reported. It is therefore better understood as a procedural milestone than a product specification shift — one that increases transparency and comparability across TIM solutions, while raising the bar for technical documentation rigor. The linkage to CE certification further suggests growing convergence between Chinese and EU functional safety frameworks in robotics, though actual enforcement mechanisms remain decentralized and case-dependent.

Conclusion

This release reflects a tightening alignment between thermal interface material performance, standardized test methodology, and international regulatory expectations — particularly at the intersection of industrial automation and functional safety. It does not introduce new material mandates, but rather activates a new verification pathway. Current stakeholders are advised to treat GB/T 42818–2026 as an emerging compliance checkpoint requiring documentation review and selective revalidation — not an immediate product replacement trigger.
