LGF reinforced Compounds

 AKROMID® Lite closes this gap between polyamide and polypropylene. Compared to polypropylene, AKROMID® Lite exhibits a better surface quality, improved mechanical properties and higher heat distortion temperature.

The mechanical properties in particular can be improved even further by using long glass fibre compounds. This applies at normal as well as at higher temperatures.

Our long glass fibre reinforced Lite compounds also demonstrate significantly increased energy absorption. The Charpy notched impact strength values for long glass fibre reinforced compounds are twice those of short glass fibre reinforced compounds. This itself is based on the fact that a particular fibre length is required to transfer forces or energy from the polymer matrix to the fibre reinforcement. At room temperature, the residual fibre length of short glass fibre reinforced compounds resulting after injection moulding is generally adequate.

The flowability of AKROMID® Lite is higher compared to standard compounds, which is very relevant especially with thin-walled components. The better flow behavior can also be observed with AKROMID® Lite long glass fiber compounds. The lower pressure demand during injection resulting from this allows the processor more freedom on the choice of injection molding machines. 

To further extend their suitability for high-temperature applications, AKRO-PLASTIC developed long glass fibre compounds with XTC stabilisation. This shielding technology extensively protects the polymer matrix against oxidative degradation at temperatures between approximately 170 °C and 230 °C. This was previously reserved for far more expensive thermoplastics such as PPA or PPS and metals. With AKROMID® C3 LGF 50 5 XTC natural (5574) AKRO-PLASTIC GmbH has developed an innovative compound. Its mechanical properties meet the highest standards, even after storage at temperatures up to 210 °C. After 3,000 h at 210 °C, for example, 80 % of the initial tensile strength is retained. A further advantage of this stabilisation is the compound is free from halogen-based additives. It is therefore highly recommended for use in electrical applications.

In order to extend the suitability for high-temperature applications even more, AKRO-PLASTIC has developed long glass fiber compounds with XTC stabilization. Due to this shielding technology, the polymer matrix is largely protected against oxidative degradation at temperatures between approx. 170 °C and 230 °C. This was previously only possible for considerably more expensive thermoplastics such as PPA or PPA. Until now, this was only reserved for considerably more expensive thermoplastics such as PPA or PPS or metals.
