Smithers Rapra: You’ll be discussing the adhesion of LSR and polypropylene (PP), why is this an important technology to discuss? What can the knowledge from this be used for?
Annette Rüppel: Self-adhesive silicone types are very common, and contain additional organofunctional silanes. They function as a bonding agent between the inorganic SI-O chains of the silicone and the functional groups of the thermoplast. They are suitable for polyamides (PA6, PA66) or Polybutylenterephthalate. Due to the surface activation method, which I will present at the conference, it is also possible to combine bulk plastics such as PP with this silicone types. As a result, the application area of LSR thermoplastic composites can be further expanded in many areas.
Smithers Rapra: Why is it important to share your research with the rest of the industry?
Annette Rüppel: This surface activation is very interesting for the material manufacturers, as it enables several material combinations.
Smithers Rapra: Within the industry you serve, what changes or developments have you noticed recently?
Annette Rüppel: This opens doors to new areas of application (i.e., re-placing bonding of two materials) and represents opportunities to optimize already existing products. Furthermore, new material combinations enable cost savings for materials (compare PP at 2 Euro/kg and PA at 6 Euro/kg) and manufacturing (manufacturing is completed in one step). In the future, the manufacture of new material combinations may create new markets. The continuously newly developed variations create a future-oriented material, which can compete with conventionally employed material groups on the market.
Smithers Rapra: What are you most looking forward to at the Silicone Elastomers World Summit 2017?
Annette Rüppel: I look forward to new contacts and exchange of ideas
