PVC or Polypropylene for cleanroom

Polyvinyl chloride (PVC) is a thermoplastic resin produced by the polymerisation of vinyl chloride. It is the world’s third most widely produced synthetic plastic polymer. Polypropylene (PP), on the other hand, is a thermoplastic polymer which is produced via chain-growth polymerisation from the monomer propylene.

PVC panels are recommended for cleanrooms and environments which are sensitive to contamination. Most plastic items for sensitive industries and cleanroom environments are made from Polypropylene, as it is resistant to fatigue. Polypropylene is used as an alternative to PVC in many situations including cleanroom environments.

PVC and PP cleanrooms provide the ideal contamination-free processing environment for operations requiring an environment that is easy to clean and sterilise.

At Total Clean Air, we specialise in the construction, design and installation of custom PVC/PP cleanrooms. We also produce PVC cleanroom accessories and equipment and we manufacture in accordance with your requirements.

PVC And PP In Cleanroom Applications
Polypropylene is used in the manufacturing of products that require high-purity, strength and rigidity. It is often chosen as a satisfactory substitute for PVC for the following reasons:

  • It is resistant to corrosion and chemical leaching.
  • It is resilient against most forms of physical damage including impact and freezing.
  • It is heat resistant and as such can withstand the heat in an autoclave and does not melt during industrial hot filling processes.
  • It can be joined to another by heat fusion instead of gluing.

When deciding on the materials and elements to be used in the construction of a cleanroom, it is necessary to keep in mind the specific requirements and working conditions of each area. PVC and PP cleanrooms employ a modular design that lets you tailor the system components to your requirements and meet cleanliness standards.

The design can impact the time needed for cleaning and maintaining accessories in the long run. Through appropriate design, the installation can be optimised and the cleanroom environment will offer long-term safety and quality standards that meet user requirements. When it comes to constructing PVC and PP cleanrooms, the traditional building method, whereby the walls and ceilings are constructed on site from raw materials followed by the application of a PVC or epoxy finish coating, is rapidly being replaced by the use of modular elements built using self-supporting, factory-made sandwich PVC/PP panels.

This change was brought about because of the many advantages offered by the use of modular elements. PVC wall panels used in cleanrooms are tested and certified to meet ISO 5 to 8 cleanliness standards. These compressed panels offer excellent chemical resistance and prevent particle emission and microbial growth. Their unique solvent-free silicone adhesive allows installation on most substrates. Seams are welded to create a uniform, sealed surface that does not harbour germs or other contaminants.

Benefits Of Total Clean Air PVC Or PP Cleanrooms

  • PVC/PP cleanrooms are used extensively in the manufacturing of electronics, food, aerospace, pharmaceuticals, hospitals, where the utmost levels of care and attention to product details are required.
  • Our PVC/PP cleanroom equipment can be manufactured to be completely free-standing and the structures can be installed within your facility or unclassified spaces to create an ISO 5 – 8 cleanroom.
  • Our PVC/PP panels are quite economical and easy to install. They are also durable, hygienic and easy to clean.
  • PVC/PP is non-shed material and as such, it ensures the amount of particles that enters the facility remains low, leading to a reduction in waste and construction residue.
  • They offer better mechanical and chemical resistance and have lower permeability to air and water.
  • Due to the fact that the materials are factory manufactured and finished to precise, pre-determined specifications, there is an obvious increase in their quality.
