CHEMICAL RESISTANT THERMOPLASTICS DUCTWORK

The most common use of plastics for ductwork is for corrosion control in:

• Air Pollution Abatement
• Ventilation
• Corrosive Exhaust Systems

Thermoplastics also offer unique advantages including:

• Light Weight
• Resistance to Corrosion
• Unlimited Serviceability
• Resistance to Chemicals

The five thermoplastic materials most commonly applied to air handling systems are:

• Polyvinyl chloride (PVC)
• Polypropylene (PP)
• Polyethylene (PE)
• Acrylonitrile Butadiene Styrene (ABS)
• Fibreglass (FRP)

Ductwork can be fabricated using the above materials in accordance with SMANCA, (Sheet Metal and Air Conditioning Contractors National Association) thermoplastic duct construction manual and AS2243.8.

Please find listed below some types of ductwork and fittings that are able to be fabricated utilizing the above materials, to all sizes and requirements.

• Round Duct
• Rectangular Duct
