Temperature-Synchronized Heated Hose for Polyurethane Metering Systems

Product Overview

Polyurethane equipment often depends on precise material behavior before the components even reach the mixing head.

If a PU material cools inside the transfer hose, its viscosity can change. In a two-component system, component A and component B may then respond differently to the same metering conditions.

The result can be unstable pressure, inconsistent flow or deviations in the material feed before mixing.

Jingcheng's polyurethane heated transfer hose is designed for single-component and two-component PU equipment, laminating machines and connecting systems where temperature stability is part of the production process.

The standard product supports temperatures up to 180°C.

Why Temperature Synchronization Matters

Two-component polyurethane systems are particularly sensitive to differences between the two material lines.

If one component becomes colder and more viscous than the other, the metering system may need to work harder to maintain the intended output.

A temperature-controlled hose helps keep the material path closer to the selected process condition.

This can support:

• More stable material viscosity

• Predictable pump response

• Consistent metering

• Reduced pressure variation

• Smoother component delivery

• More reliable mixing conditions

The goal is not simply to heat the hose, but to maintain the material condition between machine sections.

Designed for PU Equipment Connections

The hose can be used between:

• Material supply units

• Metering pumps

• Mixing modules

• Laminating equipment

• Dispensing systems

• PU processing heads

Its flexible construction allows it to connect machine sections where rigid piping would be inconvenient.

This is particularly useful when the installation includes:

• Limited space

• Equipment vibration

• Different connection angles

• Maintenance disassembly

• Non-standard fittings

Uniform Heating Along the Hose

The heating elements are arranged along the hose to minimize large temperature differences between different sections.

This helps reduce localized cold areas that may otherwise cause:

• PU thickening

• Material buildup

• Pump-pressure increase

• Uneven flow

• Difficult restart after downtime

Thermal insulation helps keep the supplied heat inside the hose instead of losing it rapidly to the surrounding environment.

Suitable Equipment

This product can be customized for:

• Single-component polyurethane machines

• Two-component PU equipment

• PU laminating systems

• Polyurethane adhesive equipment

• PU metering units

• Resin transfer systems

• Mixing and dispensing machines

• Composite-material equipment

• Replacement hoses for imported PU machinery

Customization Possibilities

Available custom options include:

• Hose length

• Inner diameter

• Material-contact inner tube

• Voltage

• Heating power

• Temperature sensor

• Machine-side fitting

• Mixing-head fitting

• Electrical connector

• Cable length

• Outer protective structure

For replacement projects, customers can provide the original hose, photos, drawings or connection dimensions.

Why This Hose Is Different from a General Heated Hose

A general heated hose may only be selected according to temperature.

A polyurethane-processing hose should also consider:

• Material viscosity

• Component A/B characteristics

• Metering conditions

• Hose pressure

• Machine interface

• Sensor compatibility

The correct configuration should match the complete PU process.
