Being greener is an essential part of any company development plan. In plastics, the need to phase out environmentally damaging CFC use has led to innovative gas solutions that will keep you compliant.
Long gone are the days when having an eco-policy was just nice to have. International protocols and corporate responsibility have combined to demand testing environmental compliance now from many suppliers across all industry sectors. The future success of your business may depend on meeting those standards.
Environmental compliance in plastics
This is particularly true in the plastics industry where traditional production methods using substances such as CFCs, are now being phased out because of their damage to the environment.
You may be one of the many producers who’ve had to make changes to meet this challenge. But is that enough? Constant innovations in technology mean it’s now possible to go further, reducing your environmental impact at every level, be it through the materials you use or the energy you consume.
Greener blowing agents
CFCs have been widely used as a ‘blowing agent’ in extrusion foaming, turning the liquid plastic into a foam which, when set, is light but relatively strong, thanks to its internal cellular structure. The result? Lighter products made with less plastic and with high insulation properties.
This is an ideal solution in sectors such as construction where Extruded Foam Polymers is a common solution to enhance thermal performance. Ideal that is, if it wasn’t for the use of CFCs. The industry needed to find an alternative and turned to Hydrocarbons (HCs) as a replacement. But now there are greener options.
Carbon Dioxide (CO2) is a versatile resource in plastic parts manufacture and has become an effective blowing agent, particularly if you need low densities and a high level of homogeneity. Also, unlike hydrocarbons, CO2 is not flammable and is significantly cost effective.
Plus, importantly, it has the lowest global warming potential (GWP) of all the agents. Even so, at BOC we ensure that all the CO2 we use has been recovered from production residues and by-products, thereby stopping it from entering the atmosphere in the first place.
The need for expertise advanced gas techniques give you better quality and improved productivity, while costing both you and the planet less. What’s not to like? Particularly when you can also access BOC expertise to make this possible. For example, you must maintain a constant flow of liquid CO2 to achieve the all-important uniform foaming results, and this can be a challenge. You need a high-pressure gas supply with accurate pump and metering system, something BOC has developed through years of research and development.
If you use extrusion foaming and you’d like to cut your carbon footprint and save money, BOC can offer technical advice of what can be achieved with our PLASTINUM® gas solutions for plastics manufacturing.
