- TPU Pneumatic Tube Composition for High-Temperature Burst Resistance
Using mono ethylene glycol as the sole chain extender, this TPU composition improves burst pressure and heat distortion resistance in pneumatic tubes.
- Sustainable EPDM Hose Composition for Pressure-Resistant Flexibility
Renewable EPDM/EPR, recovered carbon black, and sustainable fibers raise hose content up to 95% while preserving flexibility and pressure resistance.
- Dual-Textile Retractable Hose With Inflatable Reinforcement Zones
Inflatable double-fabric zones and an impermeable coating let a retractable hose resist pressure and fatigue while extending repeatedly.
- Poly(1-Butene) Resin Composition for Strength-Moldability Balance
A metallocene-made ethylene polymer extends half-crystallization time in poly(1-butene), improving pipe strength and dimensional accuracy.
- Concertinaed Composite Pipe Coating for End Exposure Without Bulging
A concertinaed coating layer shortens to expose the inner pipe end while limiting bulging and preserving pipe appearance.
- Double-Buckle Bathroom Tube Assembly With Split Connectors
Split tube-core connectors and a pressing envelope simplify double-buckle tube assembly while preserving sealing and fixation.
- Modified PTFE Fine Powder for Paste Extrusion and Hose Strength
Trace comonomer copolymerization helps modified PTFE fine powder keep low bioaccumulation while improving paste extrusion and hose pressure resistance.
- Four-Layer Expandable Water Hose Joint Structure for Wear Reduction
Intermediate elastic sleeves absorb expansion shock and reduce joint friction, abrasion, and permanent deformation in telescopic water hoses.
- High-Temperature Transfer Hose With Flexible PPS Fiber Cover
A PPS fiber cover replaces heavy metal braiding and hydrolysis-prone glass fibers to keep high-temperature transfer hoses light, flexible, and durable.
- Steel-Cord High-Pressure Hose Layout for Shock Durability
Alternating cord winding and filament twist directions reduce cross angles, disperse stress, and improve high-pressure hose shock durability.
- Short Milk Tube Rib Structure for Stable Vacuum Folding
Biasing ribs set a predictable fold point in a short milk tube, helping teatcups align faster while minimizing vacuum loss and tube wear.
- Single-Layer Coolant Hose Composition for Lightweight Engine Cooling
A polyolefin-TPE single-layer coolant hose cuts weight and bulk while maintaining heat, pressure, and recycling performance.
- Petal-Shaped Double Tube for Higher Heat Transfer Area
A hydroformed corrugated inner tube expands heat-transfer area inside a double tube, improving heat exchange without larger length or diameter.
- Immobilized Insert Tape for Flexible Pipe FLIP Mitigation
A welded insert tape with laterally immobilized wings reduces flow-induced vibration and pulsation in flexible pipe carcass windings.
- Aramid Braided Hose Structure for Burst and Impulse Resistance
Different-modulus 3 over 3 braid layers improve subsea hydraulic hose burst pressure and impulse life under high external pressure.
- Expandable Reinforced Hose Structure for Lightweight Handling
An elastic tubular hose with embedded textile reinforcement expands under water pressure and retracts after use, reducing bulk and manufacturing complexity.
- Retractable Multi-Layer Water Pipe With Low-Friction Film Barrier
A smooth plastic film layer between the inner pipe and fabric sleeve enables synchronous retraction, cuts wear, and improves pressure resistance.
- Expandable Garden Hose with Elastic Tube for Kink-Free Retraction
A pressurized elastic inner tube and end-fixed outer sleeve let the hose extend for use, then retract compactly without kinking.
