The EVA crosslinking degree tester includes: extraction device, fume hood, exhaust device and other accessories.
1.1 Function: The EVA-CCA crosslinking degree tester is used for testing the crosslinking of EVA in photovoltaic module encapsulation, crosslinking of polyethylene (PE), crosslinking of cross-linked polyethylene insulation wires and cables (XLPE), crosslinking of natural polymer ions and polymer crystallinity as well as other materials, detecting their flexibility, impact resistance, elasticity, optical transparency, low-temperature winding property, adhesiveness, environmental stress cracking resistance, weather resistance, chemical resistance, and heat sealing property.
Introduction to Crosslinking Degree Tester
2.1 Extraction device
