Sunroof frames must combine stiffness, UV durability and low VOC emissions in one molded assembly. Traditional PET-GF/MF-35 grades deliver rigidity but add weight, require lengthy drying and risk surface degradation. Thermylene™ PP-GF45% offers a glass-filled polypropylene solution that cuts frame mass by 12%, reduces component cost by 24% and simplifies molding—all while delivering UV stability and low VOC output .
By converting sunroof front- and rear-beam frames from PET-GF/MF-35 to Thermylene PP-GF45%, teams achieve a 12% mass reduction per frame and 24% lower component cost versus LGF PP, ASA or PBT alternatives . Those savings flow directly into material-spend reductions and lighter assemblies without any tooling changes.
Thermylene PP-GF45% eliminates the need for extensive drying equipment and secondary coatings, delivering a 47% capex reduction on processing infrastructure . Its no-dry requirement and engineered flowability let molders fill complex beam geometries in a single shot, reducing cycle variability, energy use and maintenance downtime.
Thermylene PP-GF45% grades are formulated for excellent UV performance and emit low VOCs during molding—addressing both exterior-component longevity and environmental-regulation targets without extra post-treatments .
Switching to Thermylene PP-GF45% cuts annual resin consumption and eliminates energy-intensive drying steps, reducing embodied CO₂ and plant energy use. Its halogen-free polypropylene base supports straightforward end-of-life recycling, helping sustainability teams hit lightweighting and circularity KPIs in one material swap.
