Two super-reflective Thermx PCT grades meet demanding requirements for LED lighting
According to Thermx PCT global business director Ruth Castillo, the company developed two high performance super-white grades of Thermx PCT that meet the challenging requirements of LED reflectors, especially for high brightness, medium-power LEDs. “Thermx PCT provides superior color and reflectance stability under heat and light compared to commonly used high temperature polyamides,” she added.
Thermx LED 0201 and Thermx LED 0201S are fiber filled, super-white PCT compounds. They withstand the demanding LED requirements for reflector resins with regard to heat and light stability — high initial reflectance; high reflectance stability under heat and light; excellent silicone adhesion; excellent processability; excellent mechanical properties; surface mount technology reflow capability; and low moisture absorption. This LED product family meets the optical and mechanical properties as well as the process requirements for specific applications. The Thermx LED 0201 also offers excellent processability and outstanding initial reflectance as well as superior reflectance stability under heat and light exposure compared to high-temperature polyamids.
The Thermx LED 0201S is particularly well suited for demanding automotive and electrical/electronics applications. This high-temperature polyester offers greater mechanical strength and flexibility in comparison to high temperature polyamides, and it is lead-free solderable with a short-term heat resistance up to 260 degrees Celsius (500 degrees Fahrenheit).
