Delivering Purging Excellence
A Multi-Generational Engineering Story
UniTemp was incepted in 1979 in Darmstadt, Germany by founders Helmut Krebs and Hans-Martin Wolff, built on a foundation of engineering discipline, precision, and long-term reliability in plastics processing.
From its earliest days, UniTemp focused on solving real production problems in injection molding, hot runner and extrusion systems. That engineering-first mindset remains unchanged more than four decades later.
The Breakthrough That Changed Purging
In 1985, UniTemp introduced PEKUTHERM®, a proprietary mechanical (physical-action) purging compound that fundamentally changed how processors clean machines.
First produced by the Pfister family in West Germany
Rather than relying on carrier resins, lubricants, or chemical reactions, PEKUTHERM® harnesses thermoelastic physical force to remove residual polymers, color, and carbon down to polished metal surfaces—without soak time, blending with incoming resins, or risking equipment damage.
This approach positions PEKUTHERM® as a category-defining solution, far beyond a commodity additive.
Continuous Production Since 1985!
PEKUTHERM® has been in continuous real-world production use since 1985, trusted by injection molders and extruders across a wide range of materials, temperatures, and machine sizes.
Its longevity is not the result of marketing cycles.
It exists because the product performs—consistently.
Family-Owned. Third Generation. Built to Last.
At UniTemp, we’re a nimble, efficient team — cleaning your machines fast, deep, and right the first time. This is the leadership team guiding our three generations of innovation and customer commitment.
Bernd Krebs
President & Chief Executive Officer
Bernd joined UniTemp in 1985 as part of the company’s second generation of leadership.
With a Bachelor of Science in Chemistry and early experience in plastics manufacturing at a German injection molding company, he brings both technical expertise and a global perspective to the business.
He helped expand UniTemp’s Hot Runner Systems operations throughout the Americas and was recognized by the Society of Plastic Engineers for advancements in back-injection molding technology.
Bernd also contributed to Pekutherm’s High-Heat (HLT) and Ultra-Low (ULT) formulations and led the onshoring of Pekutherm production in the the United States following post-COVID supply chain disruptions.
As CEO and President, he overseas UniTemp’s strategic direction, focusing on innovation, operational excellence, and sustainable growth across international markets.

“UniTemp does not compete by being the biggest. It competes by being dependable, precise, and proven.” Bernd Krebs, President & Chief Executive Officer
Reshored to the United States — 2025
To Quality & Efficiency
In 2025, UniTemp completed a full reshoring of PEKUTHERM® production to the United States, making PEKUTHERM® an All-American product, manufactured by an American team.
This move reflects UniTemp’s commitment to:
-
Supply-chain reliability
-
Manufacturing accountability
-
Quality control and formulation integrity
-
Long-term support for North American customers
Today, PEKUTHERM® is engineered, produced, and supported in the USA, reinforcing UniTemp’s hands-on approach and direct relationship with the processors who rely on its products.
