BU Source - Specialty Chemicals for other Industries


BU SOURCE GmbH was founded in 2016 by industry experts with long-term experience in business development, marketing and technology.

Our solid background is in the area of organometallic specialty products, polymer additives, pharma and fine chemicals.

We provide distinguished sourcing and consulting services in the business segments of Specialty Chemicals and Industrial Specialties.

Who We Are

Dr. Joachim Brüggenwerth,
Managing Director

helds a PhD degree in organic chemi­stry from the Uni­versity of Bielefeld, Germany and started his career in the waste management industry as project manager of new recycling technologies in 1994. In 1999 he went to Elf Atochem/ Atofina/ Arkema as key account and business development manager for functional polyolefins and high performance polymers. From 2009 to 2013 he had the position as global business development manager at Chemtura Organometallics GmbH. In 2014 he was working as Sourcing and Contract Manager for a Korean company. At the same time BU SOURCE was founded which then transferred into BU SOURCE GmbH in 2016.

Dr. Wolfram Uzick,
Managing Director

BU Source Wolfram Uzickhelds a PhD degree in organic chemistry from the Technical University of Dortmund, Germany and started his career in the chemical industry in 1986 as R&D team leader at former Schering AG, Germany, now Bayer Healthcare. Later, he had several positions with increasing responsibility in R&D and technology at former Witco and Crompton Corporation., which became Chemtura Corporation.

From 2012 to 2014 he was global marketing manager at Chemtura Organometallics GmbH. He has indepth technical  knowledge, managerial and commercial skills in the areas of olefin polymerization, catalysis, organic synthesis and fine chemicals also including quality assurance and regulatory aspects.

From 2008 to 2017 he was also board member of VAA – Association of Managers in the German Chemical Industry.

BU Source Fixed bed refining Catalysts


Ziegler-Natta catalyst components

Ziegler-Natta catalysts are mostly based on titanium tetrachloride resp. titanium trichloride as so-called “pro-catalyst” and an inorganic support material, providing specific surface properties which are important for generation of polymer particles with suitable morphology.

BU SOURCE offers titanium tetrachloride, titanium trichloride and magnesium dichloride suitable for high-mileage Ziegler-Natta catalysts. These components can be supplied separately or as blend, also in an inert catalyst-grade hydrocarbon diluent.

External stereomodifiers (“External donors”)  are beneficial catalyst additives for polypropylene processes provided by major licensors in order to improve polypropylene properties like stereospecifity and comonomer incorporation while maintaining proper process control and productivity.

BU SOURCE offers a range of the most important silane-based donorswith excellent quality and free of potentially toxic aromatic building blocks.

BU SOURCE also offers technical, applicational and market consultingin order to optimize the commercial feasibilty of certain catalyst solutions according to customers requirements.

BU Source Single-site catalyst components

Single-site catalyst components

Metallocenes are essential components for so-called “single-site” catalysts for manufacture of tailored value-added polyolefins like linear low-density polyethylene (LLDPE) for food packaging and agricultural film, high-density polyethylene (HDPE) for pipe extrusion, specialty grade polypropylenes, polyolefin elastomers and alpha-olefins.

BU SOURCE offers a range of important cyclopentadiene-based and indene-based (non-stereorigid, stereorigid) metallocenes for a variety of applications in conjunction with methylaluminoxane (“MAO”)or borane-based activators.

For metallocene manufacturing suitable precursors (“ligand” materials) are available, too.

BU SOURCE also offers technical, applicational and market consultingin order to optimize the commercial feasibility of certain catalyst solutions according to customers requirements.

Polymer Processing

Polyolefin Additives

In Europe we as BU SOURCE are representing a leading producer of polyolefin additives from China.

Our partner supplies major groups in the international market incl. South Korea, Thailand, Middle East and Europe since more than 15 years.

The product portfolio comprises: 

Primary and Secondary Antioxidants
Phenolic and phosphite antioxidants to prevent degradation during processing and long term exposure to environmental conditions.

Hindered Amine Light Stabilizer (HALS)
Amines based stabilizers are efficient radical scavengers and function by inhibiting degradation of polymers upon exposure to light.

UV-Absorber to lower degradation rate of polymers by absorbing and minimizing the radiation effect of UV-light.

Slip Agents to provide advantageous properties for fast and efficient processing.

Nucleating Agents to improve the clarity of polypropylene resins which is important for transparent film and other PP application.

All products are available in different physical shapes from granule to powder.

In addition to the individual grade we offer such essential additives as
Dust-Free One-Pack (DFO) according to customers demand:

  • Primary AO + Secondary AO
  • Primary AO + Secondary AO + Neutralizer
  • Primary AO + Secondary AO + Neutralizer + Clarifier/Nucleator
  • Primary AO + Secondary AO + Neutralizer + Antistatic Agent
  • Primary AO + Secondary AO + Neutralizer + HALS + Anti UV Agent
  • Primary AO + Secondary AO + Neutralizer + Special Additives

DFO grades are available in small cylinders shape, pls. see picture below.
