Thermoplastic Hydraulic Hose
Thermoplastic hydraulic hoses are similar to rubber hydraulic hoses usually have inner tubes, one or more stiffeners and protective covers, and the inner tubes containing the fluid are made of plastic, such as polyamides, polyesters, and even fluoropolymers. The lid protects the inner reinforcement and the tube and is typically made of a material such as polyester, polyethylene, polyurethane and PVC. The thermoplastic hose also typically has one or two reinforcement layers that provide the required strength and sufficient pressure retention. The reinforcing layer generally has a woven structure made of a material such as polyester, polyamide or aramid fiber or steel wire.
Thermoplastic hoses offer many advantages over rubber hydraulic hoses,
- These products can be formulated to handle extreme temperatures and environmental erosion of highly degradable rubber hoses. Manufacturers can be based on performance characteristics such as flexibility and kink resistance, and even custom color or shape of the product.
- In the production process, the thermoplastic hose has a self-supporting inner tube, without the spindle can be cured. (In contrast, the rubber hose is made on the inner mandrel, provides support during the machining process and holds the tube size, and must be subsequently removed). Thus, the thermoplastic hose can be made very long in length. Some special marine applications can take up to 8000 meters of continuous hose
