Laboratory testing + performance of VIM
VIM has been independently tested by a leading university laboratory to verify mechanical strength, thermal stability, and fire safety.
Vulcanized Insulation Membrane (VIM) has undergone independent laboratory testing by the Rubber Technology Research Centre (RTEC), Faculty of Science, Mahidol University, Thailand. All tests were conducted in January 2026 under controlled conditions using internationally recognized standards and calibrated instruments.
Mechanical testing confirms that VIM combines high flexibility with stable strength, allowing the membrane to withstand installation stress, movement, and long-term use without cracking or tearing. Thermal performance was evaluated using Dynamic Mechanical Analysis (DMA), demonstrating stable elastic behavior across a wide temperature range from 30°C to 200°C, supporting use in roofing, insulation, and heat-exposed environments.
Fire performance was assessed in accordance with ASTM E84 / UL 723, where VIM achieved a Class A Interior Wall and Ceiling Finish classification. This result indicates very low flame spread and minimal smoke generation, contributing to improved fire safety in occupied buildings.
All results are documented in certified laboratory reports and apply to the tested specimens only. Independent verification ensures transparency, credibility, and confidence for architects, engineers, developers, and building owners considering VIM for building and industrial applications.
