Key Selection Insight

There is no "universal" PMMA grade, only the "most suitable" choice for specific application scenarios. Successful material selection begins with accurate understanding of application requirements.

Typical Application Cases

Case: Automotive LED Taillight Project

Requirements: Heat resistance above 95掳C, excellent weather resistance, automotive standards

Material Selection: CHIMEI CM-205 (high heat resistance), Rohm XF-03 (good processability)

Result: Selected CHIMEI CM-205, passed customer acceptance

Case: High-end TV Light Guide Plate

Requirements: Light transmission >93%, extremely low impurities, excellent optical uniformity

Material Selection: Rohm 8N (optical grade), Double elephant SX-304 (high purity)

Result: Selected Rohm 8N, product brightness increased by 15%

Conclusion

PMMA material selection is a systematic decision-making process requiring comprehensive consideration of technical performance, processing characteristics, cost-effectiveness and supply chain stability.
