| Property | Typical Value (EVA-3) | Significance | |----------|----------------------|---------------| | Vinyl Acetate content | 28–33 wt% | High polarity; good adhesion to glass and metals | | Melting point (DSC) | 65–72°C | Low-temperature processability | | Melt Flow Index (MFI) | 15–45 g/10 min (190°C/2.16kg) | Suitable for film extrusion and injection | | Density | 0.945–0.955 g/cm³ | Lower than PE due to VA units | | Vicat Softening Point | <50°C | High flexibility at room temperature | | Light Transmission | >90% (after crosslinking) | Essential for PV applications |
One of the most significant challenges in designing a spacecraft like the EVA-3 is the extreme heat generated during atmospheric reentry. As the spacecraft encounters the dense layers of the atmosphere, it must withstand temperatures exceeding 2,000°C, while also maintaining a stable and controlled descent. The EVA-3's thermal protection system (TPS) is designed to address this challenge, comprising a combination of ablative materials, ceramic tiles, and advanced composites. | Property | Typical Value (EVA-3) | Significance
