**Developed by** [**Sumika Polymer Compounds**](https://www.sumikaeurope.com/?ref=plasticsiq.com)**, THERMOFILXP is a 30% glass-fibre reinforced PP, offering exceptional performance while significantly reducing cycle times. It optimises not only part production but the entire value chain from European OEMs to the end consumer.**

This innovation addresses two clear market challenges: the need for materials with superior properties to support product innovation, and the requirement for increased industrial competitiveness and cost control. THERMOFILXP provides a practical solution to boosting productivity. Thanks to the optimisations built into this solution, we can now achieve up to a 10% reduction in cycle time compared to typical PP-GF. Over the course of a year, this can represent the equivalent of a full month of additional capacity without any further industrial investment.

For our customers the impact is immediate:

- Measurable improvements in productivity
- Optimised part costs
- Increased machine availability
- Technical Excellence and Sustainability

From a technical perspective, this material sets a new mechanical performance standard within the Thermofil range:

- Tensile Modulus: up to 8,700 MPa
- Tensile Strength: up to 129 MPa
- Charpy Impact (Notched @23°C): 11 kJ/m²
- CO₂ eq. Emissions: 1.8

## **Designed for competitiveness**

This unique combination of robustness, industrial efficiency, and reduced environmental impact positions the material as a clear answer to modern industrial challenges. By pairing high performance with a controlled carbon footprint, it offers a sustainable and competitive solution for the most demanding applications.

"ThermofilXP is not just a new product developed for a specific application; it is a genuine innovation designed to strengthen our customers' competitiveness and open up new possibilities for industrial performance." — Bruno Pendélio, Head of Marketing & New Product Development Manager at Sumika Polymer Compounds Europe

To validate these claims under representative industrial conditions, trials were conducted by independent laboratory SKZ, Wuerzburg, Germany. A comprehensive testing campaign was carried out to confirm our initial estimates. Injection trials were performed on a KraussMaffei PX160 (1600 kN clamping force, 35 mm diameter screw) using the following parameters:

- Test part: Box tool (158 × 100 × 50 mm)
- Nominal thickness: 2.3 mm
- Volume: 114 cm³
- Runner system: Cold runner

Overall, ThermofilXP achieved a 12.5% cycle time reduction compared to ThermofilHP, fully confirming our initial forecasts. With ThermofilXP, Sumika Polymer Compounds has reached a new milestone in developing high-performance materials suited to today’s industrial demands. By combining significant cycle time reductions, top-tier mechanical properties, and a low carbon footprint, this new grade provides European manufacturers with a tangible lever for improving competitiveness.
