High-temperature-resistant PMMA specifically designed for automotive lighting: Double Elephant Chemical SX-304

In response to the increasing high-temperature resistance requirements of automotive lighting systems, particularly LED headlights, Double Elephant Chemical has officially launched its high-performance solution—high-temperature-resistant PMMA SX-304. This product is specifically designed for automotive lighting applications, aiming to provide exceptional high-temperature stability and optical performance.

Exceptional High-Temperature Performance 

The core breakthrough of SX-304 lies in its exceptional high-temperature performance. Compared to traditional PMMA materials, SX-304 can withstand the prolonged high temperatures generated by automotive lighting components (such as headlight lenses, daytime running light covers, position lights, taillights, etc.) during continuous operation and in engine compartment environments. It has a short-term peak temperature resistance of up to approximately 150°C and maintains excellent dimensional stability and mechanical strength even under continuous operating temperatures. This effectively addresses the risks of deformation, yellowing, fogging, and cracking that can occur in automotive lighting components under high-temperature conditions, significantly enhancing the long-term reliability, safety performance, and aesthetic integrity of automotive lighting systems.

Inherent Advantages of PMMA Material

While achieving breakthrough thermal resistance, SX-304 perfectly inherits the inherent advantages of PMMA (polymethyl methacrylate, acrylic) material:

Top-tier optical performance: featuring high light transmittance, low scattering, and excellent gloss, ensuring headlights emit bright, uniform, and precise light beams, meeting the dual high requirements of modern automotive lighting for visual effects and safety.

Robust environmental resistance: Superior weatherability enables effective resistance to UV radiation, moisture, chemicals, and temperature cycling, ensuring the headlights' long-term durability in various harsh outdoor environments.

Excellent processability: The material has good flow properties, making it easy to process via injection molding, meeting the efficient and high-precision manufacturing requirements for complex, precision automotive lighting components (such as thin-walled designs).

High surface hardness and wear resistance: The surface is resistant to scratches, helping the lens maintain a clear and bright appearance over the long term and reducing maintenance needs.

Meeting future demands

Automotive lighting is evolving toward brighter, smarter, and thinner designs, presenting unprecedented challenges to material heat resistance. The introduction of SX-304 addresses this critical need. It offers automotive lighting manufacturers a reliable, high-performance material option that enhances overall quality, safety, and design flexibility.
