Exceptional Energy Absorption: The unique closed-cell structure of EPP foam is highly effective at absorbing and dissipating significant crash energy across multiple impacts, minimizing the force transferred to the protected part or occupant in a collision event.
Lightweight Material Composition: EPP boasts an impressive strength-to-weight ratio, ensuring robust protection for car parts without adding unnecessary bulk. This helps maintain vehicle efficiency, contributing positively to fuel economy and handling dynamics.
Durability and Shape Recovery: Unlike some foams that degrade after a single compression, EPP maintains its structural integrity, allowing it to withstand repeated impacts while reliably returning to its original shape, ensuring long-term protective performance.
Customizable and Moldable Design: EPP beads can be molded into complex, precise shapes tailored specifically for various car parts, ensuring a perfect fit that maximizes surface contact and optimizes performance for specific intrusion zones or component contours.

Density and Material Formulation
We adjust the density of the Expanded Polypropylene foam, ranging typically from 20 to 200 g/L, to match the specific impact energy your car part must withstand. This fine-tuning, combined with specialized additives if needed, guarantees optimal force management. We select the perfect formulation to achieve the required compressive strength while maximizing lightweight characteristics for your application.
Precise Part Geometry and Molding
We utilize advanced CAD and molding technology to create EPP structures that conform perfectly to complex part contours, like door panels or bumper cores. This precise geometry ensures 100% contact coverage for superior load distribution. Achieving the exact required thickness and shape is crucial for meeting strict regulatory corridors and fitment tolerances within the vehicle assembly.
Targeted Energy Absorption Profile
We engineer the final piece to achieve a specific load-intrusion characteristic crucial for occupant safety simulations. This means programming the foam to ramp up resistance at a controlled rate, effectively managing peak acceleration forces. We design the density distribution within the part to create a predictable, customized stress-strain curve for that particular crash scenario.
Surface Finish and Component Integration
We customize the surface finish of the EPP, whether it requires a smooth texture for aesthetic appeal or a specific roughness for improved adhesion to other materials. Furthermore, we incorporate design features like mounting points, channels, or honeycomb structures directly into the mold, ensuring seamless, ready-to-install integration with the final car assembly process.
Door Panel Impact Absorbers
We customize these dense EPP inserts to fit directly inside door structures to absorb kinetic energy during lateral collisions. These components are precision-molded to ensure they meet regulatory side-impact testing requirements. By absorbing the initial force, they protect occupants from excessive intrusion and significantly reduce thorax and pelvic injury risks in side crashes.
Bumper Cores (Low-Speed Impact)
These structural EPP components are designed to sit behind the fascia, managing energy from minor bumps and parking incidents. We tailor their density profile across the core to provide maximum shock damping for these low-speed events. This specialized protection helps prevent costly damage to the vehicle’s chassis and structural frame elements.
EPP Pillar and Header Fillers
We mold complex, lightweight EPP shapes to fill the hollow cavities within a vehicle’s A, B, and C pillars, as well as roof headers. These fillers add crucial structural rigidity and energy management capacity to the passenger cell, effectively managing forces during oblique or rollover side impacts without adding significant overall vehicle weight.
EPP Knee and Shins Bolsters
For interior safety, we engineer EPP pads that sit beneath the dashboard and in front of the driver/passenger knees. The foam is formulated for a specific, controlled crush rate to manage impact force just before it reaches sensitive lower body areas, enhancing occupant protection during frontal and side collisions.
EPP Seat Cushion Cores and Side Wings
We produce EPP forms that serve as the structural support and integrated side-wing components within car seats. These custom cores provide consistent cushioning for comfort but are specifically engineered to manage the forces exerted on the occupant’s torso and head when a severe side impact occurs.
EPP Battery Pack Crash Protection (EVs)
For electric vehicles, we create robust, custom-fit EPP containment structures surrounding the battery pack. This specialized protection absorbs severe impact energy, guarding the sensitive cells from physical damage and potential thermal runaway events in the event of a significant side collision.
