Material Developing & Product Testing

Solutions Development and Testing

Freudenberg Flow Technologies leverages the more than 80 years of sealing and material innovation of The Freudenberg Group. With focused innovation through our 14,000-sqft Material Development & Product Test Facility located in Houston, Texas, Freudenberg Flow Technologies works to develop and certify new materials to meet the greater sealing demands for upstream applications. 

The materials development and product testing facility have International Standard ISO/IEC 17025:2017 accreditation for testing and calibration laboratories. 

Our material development and testing capabilities include:

  • Elastomer Development, Mixing, and Prototyping
  • Sour Gas (H2S)
  • HPHT
  • Thermal Cycling
  • Material Property Testing and Validation
  • Product Testing to API and ISO Industry Standards

Material Development

Elastomer Mixing Lab

Our capabilities include a mixing lab to cultivate new material recipes. Freudenberg Flow Technologies’ elastomer research group is focused on developing new formulations targeted for solving the most stringent challenges encountered by materials used in the oil and gas industry, from extreme temperature and pressure conditions to exposure to harsh drilling and completion fluids.

The mixing lab has all the necessary equipment for compounding new material recipes for seals, BOPs, packers and other non-metallic based oilfield parts. Freudenberg Flow Technologies developed a full range of elastomers, from commercial NBR, HNBR, NR, and EPDM base polymers to high-performance FKM grades and FFKM Grades, including GAZGUARD® - our trademarked RGD-resistant compounds.
