EMPOWERING U.S. MANUFACTURERS FOR GLOBAL COMPLIANCE
With nearly six decades of experience, Lorenz Kunststofftechnik continues to push the boundaries of what thermoset materials can achieve. From pioneering recycling solutions to delivering highperformance compounds for automotive, electrical, and household applications, the company shows how SMC and BMC combine durability, safety, and sustainability to meet the demands of modern industries.
Pioneering thermoset innovation since 1966
Wallenhorst, Germany – Founded in 1966 by Siegfried Lorenz and now led in its second generation by Thomas Lorenz, Lorenz Kunststofftechnik GmbH has grown into a recognized leader in the development and production of thermoset compounds, in particular Sheet Molding Compounds (SMC) and Bulk Molding Compounds (BMC). With nearly six decades of experience, the company continues to prove that SMC and BMC materials are not only state of the art but also the material of choice for high-performance, sustainable, and safety-critical applications.
From its earliest days, Lorenz Kunststofftechnik has dedicated itself to one core mission: to refine and advance the potential of thermoset materials. While many ask whether SMC and BMC still have a place in today’s dynamic materials landscape, the answer is a resounding yes. These compounds offer a unique combination of sustainability, mechanical strength, electrical insulation, and dimensional stability that continues to outperform alternative materials across industries.
Versatility across applications
The applications for Lorenz’s compounds are as diverse as they are demanding. In the electrical industry, SMC and BMC serve as the foundation for electrical cabinets, miniature circuit breakers (MCBs), and housings for household appliances such as vacuum cleaner motors. The superior dimensional stability of these thermoset materials makes them particularly valuable for automotive applications, with headlamp reflectors being a prime example. Their ability to retain precise form under thermal and mechanical stress ensures both safety and longevity, even under challenging operating conditions.
Sustainability at the core
One of the most persistent misconceptions surrounding thermoset materials is the belief that they are not recyclable. Lorenz Kunststofftechnik has been working to dispel this myth for decades. As early as 1992, the company introduced a pioneering recycling solution for SMC and BMC materials. By integrating recycling into its production processes, Lorenz demonstrates that thermosets can be part of a circular economy. This commitment to sustainability has been a cornerstone of the company’s philosophy long before it became a global industry imperative.
Superior safety and performance
Lorenz compounds are designed to meet the most stringent safety requirements. SMC and BMC can achieve high electrical insulation classes, including UL 94 V0 at thicknesses down to 0.4 mm, making them exceptionally reliable in applications where flame resistance and electrical safety are critical. In addition, these materials exhibit a remarkably low smoke toxicity index, often significantly lower than that of many comparable polymers such as polyamide (PA). This makes them a preferred choice in industries where human safety and air quality must not be compromised.
Innovation through generations
Under the leadership of Thomas Lorenz, the company remains firmly rooted in the traditions established by its founder while embracing new technologies, customer-oriented solutions, and sustainable innovation. The second generation has expanded the company’s reach, strengthening its reputation as a trusted partner to global industries. With a focus on quality, reliability, and environmental responsibility, Lorenz Kunststofftechnik continues to shape the future of thermoset applications.
A material for the future
SMC and BMC are not relics of the past—they are materials engineered for the future. Their combination of there properties, resistance to heat and chemicals, structural integrity, and environmental compatibility positions them as an indispensable choice in the modern materials toolkit. As industries demand more from materials—whether for mobility, safety, energy efficiency, or sustainability—Lorenz Kunststofftechnik is well equipped to deliver solutions that meet and exceed those requirements.
We look forward to welcoming you at our booth at K, located in Hall 7a, Stand C35.
