Polyurethane materials are processed within a narrow viscosity window, and viscosity depends on temperature. When a PU component cools in the connecting line, it thickens, the flow to the mixing or application point changes and the result is no longer consistent. JINGCHENG's Polyurethane Hose is a dedicated electrically heated line for polyurethane equipment, widely used on all kinds of laminating machines, one- and two-component polyurethane compounding equipment and connecting equipment. It is heat resistant up to 180°C, and over many years its stable quality and complete customer service have earned it a large base of quality customers.
The hose between the PU supply and the point of use has a direct effect on process stability:
Viscosity control: PU components thicken as they cool, which changes the flow through the line
Ratio and output stability: on two-component equipment, a component that cools in its hose no longer flows the way the machine expects
Cold spots: an unheated section near a fitting can let material build up and narrow the bore
Downtime and waste: thickened material in the line means cleaning stops and lost material
An electrically heated polyurethane hose keeps each component at a controlled temperature from the supply to the point of use.
The heating layer is made of uniformly braided heating elements around the inner hose. Heat is spread evenly over the inner wall, so the temperature difference along the hose is kept to a minimum and the PU material is not overheated in one place and cooled in another.
High-insulation-efficiency materials surround the heating layer and are selected with the hose surface temperature in mind. This keeps heat in the line, reduces energy use and helps keep the outside of the hose at a safer temperature.
The Polyurethane Hose has a catalog heat resistance of up to 180°C, with higher temperatures available on request. Please give us your actual process temperature so that we can confirm the right build.
A temperature sensor (Type J or Type K thermocouple, Ni120, PT100 or PT1000) can be built into the hose, with supply voltage and connector wiring matched to your equipment's temperature controller. On two-component machines, each component line can be specified separately.

Temperature sensor | Type J thermocouple, Type K thermocouple, Ni120, PT100, PT1000, or other |
Hose length | 3 m, 4.5 m, 5 m, 6 m, 10 m, or other |
Inner diameter | Φ8, Φ12, Φ16, Φ19, Φ25 mm, or other |
Hose working pressure | 4 MPa, 10 MPa, 20 MPa, 35 MPa, or other |
Rated power | 110 W/m, 150 W/m, 170 W/m, 200 W/m, or other |
End fittings (each end) | US, British or metric thread, or other |
Wiring | Pin number, wire color and function defined for the controller end and the gun/tool end |
JINGCHENG heated hoses are identified by a model code such as JCH-200-16-B-3X220-P2-8:
200: working temperature in °C (200 = 200°C)
16: hose inner diameter in mm (16 = Φ16)
B: inner tube material (B = stainless steel corrugated tube; TB = PTFE hose with stainless steel braid; T = PTFE hose; X = special material)
3X220: working voltage (220 = 220 V; 3X220 = three-phase four-wire 220 V)
P2: temperature sensor (P2 = PT100 two-wire; P3 = PT100 three-wire; K = Type K thermocouple; J = Type J thermocouple; W = no sensor; T = special sensor)
8: working pressure in MPa (8 = 8 MPa)
Ambient temperature: -40°C to +55°C
Relative humidity: not more than 85%
Atmospheric pressure: 86 kPa to 106 kPa
Voltage range: 12 Vac to 380 Vac
The surrounding medium should not contain gases that corrode metal or damage insulation, or conductive media, and severe mold must not be present. For special environments, contact us for a customized hose.
Wire the hose according to its technical parameters and the pin table supplied with it.
Do not twist the hose sideways during or after installation; lateral twisting can cause leakage, flow loss, hose damage or fire.
Avoid sharp bends; bending the hose too tightly can damage it and cause short circuit, leakage or fire.
The hose should be operated only by authorized and trained personnel, ideally the same dedicated operators.
Unauthorized modification or adjustment of the hose voids the warranty.
If you meet a problem not covered by the instructions, contact us so that our engineers can guide the installation.
Inquiry: send us your requirements by phone, fax or the inquiry form.
Specification confirmation: our engineers propose the most suitable specification as a quotation reference.
Quotation: we issue a quotation; you confirm with a purchase order.
Production: the hose is built in our factory to the confirmed specification.
Inspection and packing: every hose is checked for defects and packed.
Shipment: the hose is shipped to your designated address.
Material and temperature: tell us the polyurethane system and the temperature each line must hold (standard heat resistance up to 180°C).
Size and length: choose the inner diameter for your flow (seven catalog sizes from 1/4" to 1") and the length from the supply to the point of use.
Electrical: specify the supply voltage (380 Vac, 220 Vac, 110 Vac or 12 Vdc), the power per meter and the sensor type of your controller.
Connections: give the thread standard at each end (US, British or metric) and the connector and pin layout for each component line.
Routing: route the hoses without twisting and keep bends gentle, especially next to the fittings.
