◎ Enhanced Softness and Strength
Crafted from 100% virgin wood pulp with delicate embossing, each tissue achieves an optimal balance of luxurious softness and structural integrity. The embossing process not only creates an elegant texture but also increases the surface area, improving absorbency without compromising gentleness on the skin. The long, pure fibers ensure high wet strength, preventing tearing or linting during use. This makes it ideal for facial care, guest amenities, and sensitive skin applications, offering a noticeably premium experience compared to standard tissues.
-
◎ Brand Promotion and Aesthetic Appeal
The tissue box serves as a versatile branding canvas, allowing full customization of logos, colors, patterns, and text. Whether for luxury hotels, corporate gifts, boutique retailers, or event souvenirs, the design can be tailored to reflect brand identity and enhance visual cohesion in any setting. The box itself is made from sturdy, high-quality cardboard with a smooth finish, ensuring durability and a polished appearance. This customization capability turns a practical item into a powerful marketing tool that reinforces brand recognition and leaves a lasting impression.

Frequently Asked Questions
Q What is the operating temperature range of the silicone heat shrink tube?
+
The silicone heat shrink tube has a usage temperature range of -50°C to 170°C, making it suitable for both high-heat industrial environments and cold-resistant applications. The shrink temperature exceeds 100°C, ensuring reliable performance across a wide range of conditions.
Q What shrink ratios are available for these silicone heat shrink tubes?
+
These silicone heat shrink tubes are available in two conventional shrink ratios: 1.7 times and 2 times. Both options come in a comprehensive range of specifications from 1mm to 220mm inner diameter, with detailed tolerance and packaging modes for each size to suit various application requirements.
Q What industries and applications are silicone heat shrink tubes used for?
+
Silicone heat shrink tubes are widely used across heavy and light industry electrical fields (semiconductor devices, generators, motors, fiber optic jackets), household appliances (ovens, fryers, water heaters, air conditioners), transportation equipment (vehicle sensors, spark plugs, wiring harnesses), and various roller and industrial applications including dental equipment and thermoformed preforms.
Q What are the key mechanical properties of the silicone heat shrink tube?
+
The silicone heat shrink tube offers a tensile strength of ≥6.5 MPa, a tearing/peeling strength of ≥25 KN/m, an ultimate elongation of ≥400%, a dielectric strength of ≥20 KV/mm, and a hardness of 65±10 (Shore A). It also carries a UL-94 fire retardant grade, making it suitable for safety-critical electrical insulation applications.
Q What is the minimum order quantity (MOQ) for silicone heat shrink tubes?
+
The MOQ varies by size. Smaller diameter tubes (1mm–2.5mm) have an MOQ of 2000M, mid-range sizes (3mm–11mm) range from 1000M to 1200M, and larger diameter tubes (25mm and above) start from 75M to 200M. Packaging quantities per roll also vary from 25M to 200M depending on the specification.
Q Can silicone heat shrink tubes be used for outdoor and harsh environment applications?
+
Yes. Thanks to their wide temperature range (-50°C to 170°C), high dielectric strength (≥20 KV/mm), excellent rebound resilience (≥35%), and UL-94 fire retardant rating, silicone heat shrink tubes are well-suited for outdoor, high-voltage, high-temperature, and mechanically demanding environments including power plants, substations, and transportation equipment.
