FKM Elastomers

Friday, March 19th

Learn the multiple structural and performance benefits of Neuburg Siliceous Earth in your FKM (Fluoro-Elastomer) formulations.

  • Very low sieve residue
  • Good mixing and dispersion properties
  • High tensile strength
  • High abrasion resistance
  • Long flow time with short vulcanization time
  • Easy deflashing
  • Low compression set
  • Good resistance to substances (fuel, oil, water, acid)
  • Avoidance of mold fouling on dies caused by filler

Polyamide PA 6 and PA 66 Applications

Friday, April 9th

Learn the benefits of using Calcined Neuburg Siliceous Earth in Polyamide 6 and 66 applications.

  • Enables low warpage, impact-resistant parts with little or without impact modifiers as an alternative to PA 6 GF15 impact modified
  • Extraordinarily high impact strength, even at low temperatures
  • Great weld line strength
  • No graying of black compounds
  • High melt flowability
  • Low warpage
  • Extremely high ultimate elongation

Rubber Elastomers

Friday, April 23rd

See how using Neuberg Siliceous Earth adds performance and value to multiple rubber and elastomer applications

  • Lower water absorption (compared with carbon black)
  • Avoid deposits on dies caused by filler
  • Total formula cost reduction potential
  • Good mixing and dispersion properties
  • Good extrusions properties
  • High surface quality
  • High electrical resistance
  • Better compression set

Silicone Rubber, AEM

Friday, June 11th

Learn how Neuberg Siliceous Earth provides functional and mechanical benefits to Silicone Rubber compounds & AEM

  • Partial replacement of ATH with Aktisil Q, Aktifit Q or Silfit Z 91 provides practically the same flame-retardant properties of pure ATH
  • Good extrusion properties and collapse resistance
  • Reduced stickiness
  • No blooming
  • Drier surface
  • Very good oil resistance
  • Low tension and compression set without post cure
