NBR/PVC Rubber Foam Product Information

NBR/PVC Rubber Foam Technical Specification

The following table retains the existing technical data supplied for the referenced NBR/PVC foam grade. Final material selection should be confirmed according to density, thickness, thermal requirements, operating conditions and finished application.

What Is NBR/PVC Thermal Insulation Foam?

NBR/PVC rubber-plastic sponge is a flexible insulation material made from nitrile rubber and PVC. The referenced thermal-insulation product is described as a soft black closed-cell foam designed for cold and heat insulation applications.

Existing product information lists thermal conductivity of approximately 0.034 W/m·K at an average temperature of 0°C and a moisture resistance factor of ≥10,000 for the described insulation material.

The material can be supplied in sheet and pipe forms for suitable HVAC and refrigeration applications. It is used for insulation of refrigeration equipment, chilled-water pipes, condenser-water pipes, air ducts and hot-water pipes.

The existing product information identifies an operating range from approximately -40°C to 110°C. Final temperature suitability should be confirmed for the selected foam grade and installation structure.

NBR/PVC Foam for HVAC Insulation

Flexible NBR/PVC rubber foam can be used for thermal insulation in central air-conditioning systems, ductwork and HVAC equipment where reduced heat transfer and moisture control are required.

The flexible structure allows the material to be fitted around suitable duct and equipment surfaces. Sheets can also be cut into customized dimensions according to installation requirements.

Adhesive backing can be added where easier positioning on suitable metal duct surfaces is required.

NBR/PVC Foam for Chilled-Water Pipe Insulation

Low-temperature pipelines can be exposed to condensation when the surface temperature falls below the dew point of the surrounding air. Insulation materials for these systems therefore need both thermal performance and resistance to moisture penetration.

The referenced NBR/PVC thermal insulation grade is intended for applications including chilled-water pipes and condenser-water pipes. Its flexible foam construction allows insulation around suitable piping and equipment geometries.

Required insulation thickness depends on pipe temperature, ambient temperature, humidity, pipe diameter and system design and should be determined for the specific project.

NBR/PVC Foam for Refrigeration Equipment

NBR/PVC rubber foam can be used as flexible thermal insulation around suitable refrigeration units, equipment panels and associated piping systems.

The combination of low thermal conductivity, flexibility and moisture resistance makes the referenced grade suitable for cold-insulation applications where condensation control is important.

Typical NBR/PVC Thermal Insulation Applications

Thermal Conductivity and Energy Loss Control

Thermal conductivity indicates how readily heat passes through an insulation material. A lower value means the material transfers heat more slowly under the stated test conditions.

The existing product description lists thermal conductivity of approximately 0.034 W/m·K at an average temperature of 0°C for the referenced NBR/PVC insulation material.

Actual insulation-system performance also depends on material thickness, installation quality, operating temperature and environmental conditions.

Moisture Resistance and Condensation Control

Moisture control is particularly important on chilled-water and refrigeration systems. Water vapor entering an insulation system can reduce thermal performance and contribute to condensation-related problems.

The existing product information describes the referenced NBR/PVC insulation material as having a moisture resistance factor of ≥10,000. This characteristic supports its use in suitable low-temperature insulation systems.

Joints, seams, penetrations and exposed edges should still be handled according to the design requirements of the complete insulation system.

Flexible NBR/PVC Foam for Duct and Pipe Installation

Flexible rubber foam is easier to form around suitable pipes, elbows, equipment surfaces and ductwork than rigid insulation materials in many applications.

Topsun can supply NBR/PVC foam in different widths and thicknesses and can provide cutting or adhesive backing according to suitable installation requirements.

For prefabricated duct applications, wider foam formats can also help reduce the number of separate pieces required during installation.

Vibration Damping for HVAC Equipment

The elasticity of NBR/PVC rubber foam allows it to act as a flexible interface between suitable equipment components. It can help attenuate vibration at joints, supports, suspensions and panel interfaces.

Where vibration damping is a primary requirement, density, thickness, compression and equipment load should be evaluated according to the actual assembly.

How to Select NBR/PVC Thermal Insulation Foam

Material selection should consider the complete insulation system rather than density or thickness alone.

• Application: identify whether the material is used for chilled water, refrigeration, ductwork, hot-water piping or equipment insulation.

• Cell structure: confirm the required foam structure for the intended thermal and moisture-control function.

• Density: specify the required grade if already established.

• Thickness: select according to thermal performance and condensation-control requirements.

• Width and length: specify sheet or roll dimensions required for installation.

• Operating temperature: provide minimum and maximum system temperatures.

• Ambient conditions: provide temperature and humidity information for condensation-sensitive systems.

• Adhesive backing: specify whether plain foam, one-side adhesive or double-side adhesive is required.

• Fire-performance requirement: identify any project-specific requirement before material selection.

• Quantity: provide sample, trial and estimated production requirements.
