Thermylene™ PP-GF40% for Front-End Modules at a European OEM

Introduction

A European OEM molding front-end modules—integrated radiator supports, headlight mounts, and grille assemblies—sought to reduce part weight, cut material cost, and simplify molding of complex ribs and snap-fits. Their existing PA6-GF30/PPLGF-30 grades delivered strength but added mass, required lengthy drying and risked warpage. Thermylene™ PP-GF40% answers the challenge by offering equivalent stiffness, easier processing, and lower total part cost.

Weight Reduction and Cost Down

The OEM achieved meaningful weight savings and a corresponding drop in resin spend by converting the front-end module from PA6-GF30/PPLGF-30 to Thermylene PP-GF40%. Without changing the tool or part design, teams met their cost-reduction targets while advancing vehicle lightweighting goals.

Ease of Molding Complex Geometries

Thermylene PP-GF40% flows uniformly into tall ribs, snap-fit features and thin-wall sections thanks to its consistent melt-flow properties and low shrinkage. Molders eliminated pre-drying, reduced cycle variability and saw more stable cavity balance on multi-impression tools. The result: fewer rejects, faster startups and smoother production on existing presses.

Structural Integrity under Load

Thermylene PP-GF40% delivers the flexural stiffness and impact resistance needed in front-end modules to withstand parking-lot bumps and road-debris strikes. Its glass-filled formulation maintains dimensional stability under thermal cycling in the engine bay, preserving grille alignment and panel gaps without secondary adjustments.

Sustainability Benefits

Switching to Thermylene PP-GF40% cut the OEM’s annual resin usage and eliminated energy-intensive drying steps. The polypropylene base contains no halogens or additives that hinder recycling, supporting end-of-life circularity goals. Sustainability teams met both lightweighting and recyclability KPIs with a single material change.
