ROHM PLEXIGLAS 8N: Weather Resistant PMMA for Automotive Lighting (Global Supplier)

1. Luxury Brand ADB Headlight Project: ROHM PLEXIGLAS 8N Redefines Lighting Reliability

A top-tier European luxury automaker faced three critical challenges in its flagship SUV’s ADB headlight development:

1. Optical Limitation: The original lens material only achieved 88% light transmittance, failing to meet the required irradiation distance and uniformity for ADAS safety ratings.

2. Weather Resistance Shortfall: In tropical test zones, the lens yellowed by ΔY > 3.0 after 6 months, with transmittance dropping by 15%—far below the brand’s “5-year no visible aging” commitment.

3. Processing Inefficiency: Complex curved injection molding led to a mere 75% yield, prolonging mass production timelines.

ROHM PLEXIGLAS 8N became the game-changer: Its 92% transmittance (ISO 13468) increased effective irradiation distance by 20%, while 0.5% haze ensured A-level light uniformity. Our customized UV-resistant modification kept ΔY < 0.8 even after 10,000 hours of accelerated aging.

As a ROHM PMMA supplier, our value lies in:

1. Collaborating with ROHM PLEXIGLAS technical teams to optimize injection parameters (mold temp 85℃, injection pressure 80MPa), boosting yield to 95%.

2. Leveraging bonded trade and global warehouse networks (Europe, North America, Asia) to enable “3-day sample approval + 15-day bulk delivery”, helping the new model launch 2 months ahead of schedule.

3. Providing full material traceability, with each batch traceable to ROHM’s original production lot, meeting automakers’ supply chain compliance requirements.

2. New Energy Vehicle Headlight Lightweight Project: ROHM PLEXIGLAS 8N Balances Performance & Cost

A leading NEV manufacturer aimed to reduce headlight weight to improve range, requiring lens thickness to be reduced from 3.5mm to 2.8mm while maintaining optical and weather performance.

ROHM PLEXIGLAS 8N’s high mechanical strength (3300MPa tensile modulus) and processability made it ideal: We achieved 2.8mm ultra-thin lens molding, reducing weight by 20% while retaining >91% transmittance. Its scratch-resistant surface (H-level hardness) eliminated damage risks during assembly and use.

Our supply capabilities include:

1. Supplying ROHM PLEXIGLAS 8N with official certification and full performance reports (transmittance, heat distortion temperature, etc.).

2. Offering free sampling and process simulation for lightweight projects to validate feasibility.

3. Activating the “NEV Project Green Channel” for urgent orders with 72-hour delivery globally.
