PVC Pipe
PVC Pipe
2025-07-09
Polyvinyl Chloride (PVC) pipe is a versatile thermoplastic piping material widely used in construction and industrial applications. PVC pipes are manufactured through an extrusion process, resulting in a product with a smooth inner surface (with a typical surface roughness of 0.0015 mm) that minimizes friction losses. The material exhibits excellent chemical resistance with a pH tolerance range of 2-12, making it suitable for various corrosive environments.

Braided Tool
Braided Tool
2025-06-27
A braided tool refers to a specialized implement constructed using advanced braiding technology, where multiple strands of high-performance materials are interwoven to create a composite structure with superior mechanical properties. Modern braided tools typically combine carbon fibers (tensile strength: 3,500-7,000 MPa), aramid fibers (modulus: 70-200 GPa), and sometimes metallic wires in precise geometric patterns. The braiding angle (typically between 30°-60°) significantly impacts the tool's performance characteristics, allowing engineers to tailor properties like torsional stiffness (ranging from 50-500 N·m/rad) and axial load capacity (5,000-50,000 N) for specific applications.

Silicone Rubber Heat Shrinkable Tube is a specialized polymer product designed for insulation, protection, and strain relief in high-temperature and harsh environments. Composed of high-purity silicone rubber with cross-linked molecular structures, it exhibits exceptional thermal stability, chemical resistance, and electrical insulation properties. When exposed to heat (typically 120°C-200°C), the tube shrinks radially by 2:1 or 3:1 ratios to form a tight, conformal seal around substrates.
Pattern Heat Shrink Tube
Pattern Heat Shrink Tube
2025-06-19
Patterned Heat Shrink Tube is a specialized type of heat-shrinkable tubing that features distinct surface patterns (such as ribs, grooves, or textures) designed to enhance grip, flexibility, or identification. These tubes are manufactured from cross-linked polyolefin or other polymer materials with a shrink ratio ranging from 2:1 to 4:1, and they typically operate within a temperature range of -55°C to 125°C. The patterned surface increases surface area by 15-30% compared to smooth tubes, improving tactile properties and strain relief.
