The PVC myth
Many myths about this material have been swirling around for decades – something which has led to it having to contend with many prejudices. We examined some of these rumors which we can now dispel with proven arguments.
"PVC contains poisonous chemical stabilizing agents and is harmful to health"
It is exclusively hard PVC (PVC-U) which is used in the production of GHS products which does not include the use of softeners or heavy metals. Chemical stabilizing agents are needed for the processing and here we place importance on the use of sustainable additives and use calcium-zinc based stabilizing agents. These give our products the best mechanical properties and they are distinguished by a high degree of weathering resistance. An independent technical study conducted by the TÜV Rheinland (certification and inspection body) confirmed that GHS products do not emit any volatile, organic or carcinogenic substances.
"PVC production is cost and resource-intensive"
The thermoplastic PVC contains 57 % chlorine and 43 % hydrocarbon. In comparison to other polymers, PVC production is therefore less dependent on petroleum or natural gas. Today it is particularly crude oil and cooking salt which are used as the raw material basis. GHS uses an innovative technology in the production process which ensures a high performance with cost-efficient production. Thanks to well thought out processes and procedures, GHS guarantees an energy-efficient and resource friendly production in which, amongst other things, used cooling water, production rejects and production waste are returned to the manufacturing process which, in turn, saves costs and resources.
"PVC is difficult to recycle"
Today, PVC can be repeatedly recycled and added to new productions as recycling material without damaging the polymer chains in doing so. The raw PVC profiles by GHS can also be recycled 100 per cent. All the waste which occurs in production as well as defect materials are also returned to production and can be processed again. When GHS Permanent Homes have reached their maximum lifespan, entire concrete houses can be torn down, crushed and used as filling material in road construction.
"PVC is not UV resistant and becomes brittle after a short while"
PVC does, in fact, have a very stable chemical composition which makes the material weather resistant and particularly durable. Additives such as the Ca-Zn stabilizing agents which are used at GHS improve the physical properties such as temperature, light and weather resistance and, as a result, the material’s life span. PVC has also proven to be a highly reliable material in strong heat, salty water or salty air in coastal regions.
"PVC releases deadly gases in fires"
PVC generally has low flammability but, similar to other organic materials which are used in buildings, it can also burn if there is sufficient heat development. In contrast to alternative materials such as other plastics or wood, the PVC elements by GHS are self-extinguishing. If the source of ignition is removed, the material will stop burning. Heat generation is also relatively low and the material is more likely to char than to produce burning drops. And, in the case of fire, PVC also releases a strong-smelling warning chemical which means it is quickly noticed by anyone nearby and this aids the rapid extinguishing of the fire.
"PVC production is dangerous"
GHS fulfills the highest standards. The production facilities are closely monitored and controlled to prevent the discharge of dangerous substances into the atmosphere. Areas in which there is work with open powder material are particularly protected and these are fitted with special ventilation and filter systems to offer employees maximum protection. Thanks to the utmost care and best protective mechanisms, GHS is able to look back on an accident-free production record.
