Lavanta 5115 WH 224 is a 15% glass fiber-reinforced polycyclohexylene terephthalate (PCT) compound developed specifically for LED electronic packaging applications that use surface mount technology. The injection molding grade can be molded at a lower temperature (125°C/257°F) than competitive PCTs and maintains 100% of its maximum crystallinity. Cooler molds enable cycle times to be reduced, resulting in lower energy use and reduced cost.
The compound also has high reflectivity (greater than 95%) with excellent whiteness retention even after thermal and light aging. The new PCT grade also has lower moisture absorption and excellent dimensional stability compared to PPA. It has a tensile strength of 78 MPa (11,312 psi) and elongation of 1.6%.
Improved version
Solvay plans to expand the Lavanta HPP product series with an improved version with greater whiteness and whiteness retention.
