  • PP matrix with fully cross-linked EPDM phase
  • Very good 2K adhesion to PA6 and PA66
  • Also suitable for under the hood applications

Albis Plastic GmbH has launched new polyamide adhesion modified compounds. ALFATERXL is a blend of a polypropylene matrix with a finely dispersed, fully cross-linked EPDM phase and belongs to the group of thermoplastic vulcanizates (TPVs).

PP matrix with fully cross-linked EPDM phase

The material is available in shore hardness A55, A70 and A85. It is resistant to weather, ozone, aqueous solutions, acids and alkaline media, and can be used in a wide temperature range (-40 °C to +130 °C). As its natural appearance is very light, the material can be easily colored.

Very good 2K adhesion to PA6 and PA66

Tests conducted together with the SKZ Würzburg have confirmed the very good 2K adhesion to PA6 and PA66. Peeling tests of ALFATERXL with shore hardness A55 in accordance to VDI 2019 typically resulted in cohesive break of the ALFATERXL TPV. This means that the adhesion to polyamide proved stronger than the inherent strength of the TPV. A further feature of the material is the good adhesion when using inserts (cold inlays).

Also suitable for under the hood applications

The new blends are suited for the manufacture of ‘hard-soft’ components in various sectors, such as the automotive and electric / electronic industries. In the automotive segment, due to its high temperature resistance, the material is also suitable for use in under the hood applications, e.g. seals, covers and cable ducts. Given its low emission and low fogging properties the material also meets the requirements for interior automotive parts and housing components.
