ALBIS Plastic expands thermoplastic elastomers portfolio

ALBIS PLASTIC GmbH is expanding its portfolio of thermoplastic elastomers by including polyamide adhesion modified ALFATERXL compounds available in shore hardness A55, A70 and A85.

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). The material 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 coloured.

ALBIS says numerous tests have confirmed the new adhesion modified ALFATERXL types offer an “excellent” 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 highlight, says ALBIS, is the good adhesion when using inserts (cold inlays).

The new ALFATERXL types are said to be perfectly suited for the manufacture of 'hard-soft' components in various sectors, such as the automotive and electric / electronic industries. In the automotive industry, thanks 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 new ALFATERXL series also meets the requirements for interior automotive parts and housing components.
