 Covestro Makrolon ET3137 PC pellets Description 

Application

Covestro Makrolon ET3137 PC pellet Advantage

• Branched polycarbonate material. Makrolon ET3137 uses a branched polymer structure processing method, which makes the material have higher melt strength, which is convenient for large and complex profiles, especially in multi-wall applications with high requirements for uniform wall thickness.
• UV-resistant polycarbonate material. Makrolon ET3137 PC material contains UV-resistant ingredients, and the products made of it can be used outdoors for a long time, such as transparent greenhouse panels, windows, etc.
• Better low-temperature impact resistance. Branched polymers have better low-temperature impact resistance. The cantilever beam notch impact of ET 3137 PC material under -30℃ test environment can reach 16kJ/㎡, which is higher than conventional polycarbonate materials and is suitable for low-temperature environment applications.
• Good processing performance. The branched polycarbonate Makrolon ET 3137 has a melt index of 7g/10min at 300℃ and 1.2kg test environment. It has a high viscosity melt and has higher tensile strength than conventional polycarbonate materials. The tensile strength reaches 100MPa at 2.0mm/min test environment, which facilitates the stretching manufacturing of large and complex profiles.
