Our R & D team is comprised of diverse professionals – from electrical engineering to materials science. They drive our technical innovation and manufacturing innovation and also specialize in automotive research and development. The team has the skills and experience to design and execute technology, developing responsive customer solutions and production innovation, from concept to commercial reality.

Key pillars of our innovation culture and capabilities include:

Heat-shrink machines tested in our innovative laboratories

State-of-the-Art laboratories at each location

Laboratories and test facilities for our heat-shrink products are situated in each of our global locations, benefitting from collaboration and production innovation of the highest quality. Our test facilities incorporate a range of core equipment for concept and pilot development. These include compounding and lab extruders, complemented by a wide variety of analytical equipment, ranging from standard mechanical testing to thermal analytical tools such as DSC and DMA equipment. Specialized labs for simulation, environmental and electrical testing are available to support solution development needs.

DSG-Canusa’s R&D team

We have assembled a highly knowledgeable research and development team at our Rheinbach site. Experts in the fields of polymers and adhesives, they have access to a variety of materials for trials with specialized test equipment. Their focus on production innovation, manufacturing innovation, technical innovation and innovative machine solutions increases our capability to successfully take on challenging projects.

Materials Capability

The ability to innovate and provide solutions to our customers stems from our strength in converting customer requirements into material technologies and customized solutions. Critical to this is a strong foundation in polymer materials technologies and a detailed understanding of structure-property relationships.

The following is a list of key material technologies with which we routinely work:

  • Polyolefin 
  • Polyester 
  • PVC 
  • Polyamide 
  • EVA 
  • PVDF 
  • Fluoro-Elastomers 
  • Silicon-Elastomer and Gums 
  • EPDM 
  • Butyl-Elastomers 
  • Thermochromatic Coatings 
  • Polymer Graft Systems 

Equipment Capability

DSG manufacturing utilizes equipment from world-class suppliers as well as custom built equipment and designs built in our own Machine Technology Center (MTC) for our work in production innovation. Extrusion equipment and our irradiation and chemical cross-linking processes are both used in our heat-shrink manufacturing plants. Beyond this, our heat-shrink manufacturing has specialized equipment for expanding tubing and is capable of making heat-shrink products with expanded inner diameters from 3/64″ (1.2mm) to 9″ (229mm) and up to a 6:1 shrink ratio.
