Ventec International Group is pleased to announce that UL’s evaluation of two of Ventec’s halogen-free, phenolic-cured high-CTI substrates has received authorization to apply the UL mark. VT-441C and VT-447C FR15.1 materials have thus been recognized for achieving 150°C Maximum Operating Temperature (MOT) for electric and mechanical RTI (Relative Temperature Index).

UL's investigation of Ventec's mid-Tg VT-441C and high-tg VT-447C halogen-free substrates has been completed and full compliance with the applicable requirements including 150°C MOT (Maximum Operating Temperature) for electric and mechanical RTI (Relative Temperature Index) has been determined.

Offering exceptional UL RTI performance, both high-CTI substrate materials ensure reliability in high applied voltages in harsh and humid environments. With high voltage CAF resistance, Grade 0 (>600V) Comparative Tracking Index (CTI) and glass transition temperatures (Tg) of 155°C and 175°C, the versatile halogen-free materials are the perfect high-reliability PCB choice for use in extreme high-temperature/humidity applications. These include DC/DC power modules, IGBT applications, motor controllers, high-lumen output LED devices, battery charging, OBC chargers for EV vehicles, and several other automotive “underhood” applications.

The prepregs are available in roll or cut-to-size panel format, with laminates supplied in sheets or cut-to-size panels with core thicknesses of 0.004” (0.10mm) to 0.200” (5mm). They are also offered in a wide range of copper foil thicknesses including heavy coppers. This versatility is ideal for both single-layer and multiple-layer PCB designs.

Mark Goodwin, COO of EMEA & Americas, commented: "Achieving UL authorization for our industry-leading 150oC MOT performance is fantastic news. As a complement to our full halogen-free and thermal management solution series, our customers can access epoxy materials that meet virtually any high-reliability performance requirements for the world’s most demanding applications."
