XHTMS-50120 is a high-performance polyimide (PI / Kapton) tape coated with silicone pressure-sensitive adhesive, engineered for high-temperature masking and protection in electronics manufacturing. The 50 μm Kapton film substrate provides outstanding thermal stability, dielectric strength, and mechanical toughness, while the silicone adhesive ensures clean removal with zero residue after exposure to soldering temperatures up to 260–280°C. It is widely used for gold finger protection during wave soldering, PCB masking during reflow, and shielding of chassis and cabinet components during high-temperature spray coating processes.

The tape surface shall be uniform and free from defects including air bubbles, pinholes, creases, wrinkles, and blemishes. Each roll shall be wound evenly without edge damage or telescoping. Inspections shall be carried out in accordance with GB/T 7125, GB/T 2792, and GB/T 7752.
Each roll is individually wrapped in a plastic film inner layer and packed in a corrugated carton outer box. Custom roll widths, lengths, and core sizes are available upon request.
Store rolls upright or flat in original packaging. Recommended storage conditions: temperature 18–28°C, relative humidity 45–75% RH, in a dry, clean, and well-ventilated environment away from direct sunlight, open flames, and heat sources. Shelf life: 6 months from date of manufacture. Product may still be used after 6 months if re-tested and confirmed to meet all specification requirements. For best performance, use within 2 months of receipt.
