The industry has learned from experience and, together with the authorities, has introduced preventative measures to eliminate every conceivable risk. Today it can be stated that where up-to-date technology is being used, the handling of uPVC is absolutely safe. Up to the beginning of the seventies, the gaseous, monomeric vinyl chloride VC was a negative aspect in the production of uPVC, which led to illness.
Simultaneously, there was the suspicion that uPVC end products might also , under adverse circumstances, emit the remaining VC. This problem has been solved. The measures introduced to improve technical industrial production and working hygiene have led to the disappearance of this critical substance.
In the age of quick fashion, homeowners are always on the lookout for inexpensive and durable window treatment solutions that would easily go with the changing looks of their rooms. PVC blinds fit the bill perfectly. Not only they are much cheaper than wooden or aluminum blinds, but they also come with superior heat and moisture resistant qualities.
Let look at some of the primary factors driving the rising popularity of PVC blinds. With so many plusses, it is no wonder that the market is flooded with PVC blinds. But like all synthetic materials, PVC too comes with some serious disadvantages. PVC is made of plastic, which contains many toxic chemicals. PVC blinds may contain traces of hydrochloric acid, vinyl chloride, dioxin, lead, mercury, and cadmium.
This toxic blend of chemicals is known to contribute to the development of cancer, congenital defects, respiratory distress, and much more. The manufacturing process of PVC also gives rise to toxic by-products that are extremely harmful to our environment. Are they Safe? PVC blinds do disintegrate in the sun and heat, but the effects are not visible. Prolonged exposure to heat and light slowly separates the constituent materials in the form of tiny particles which then blend with the air.
These tiny particles can be inhaled, and therein lays the problem. The biggest threat lies in the form of lead contamination. Dioxin comes from many sources, according to EPA. PVC is an extremely small source, so small that levels of dioxin in the environment would be essentially unchanged even if vinyl were not being manufactured and used every day in important products.
Overall dioxin levels in the environment have decreased by more than 90 percent since , during which time production and use of vinyl have more than tripled. Phthalate plasticizers are added to vinyl when flexible products are being made. Phthalates have been thoroughly studied and reviewed by a number of government scientific agencies and regulatory bodies world-wide and these agencies have concluded that phthalates used in commercial products do not pose a risk to human health at typical exposure levels.
Information collected by the Centers for Disease Control and Prevention over the last 10 years indicates that, despite the fact that phthalates are used in many products, exposure is extremely low — significantly lower than any levels of concern set by regulatory agencies.
Stabilizers are added to vinyl formulations to lubricate and control the integrity of the material in the manufacturing process, or for coloring. They are held tightly in the material. In the United States, lead and cadmium have been almost entirely phased out of vinyl consumer products. The Vinyl Institute.
Tweets by AmChemistry. Building and Construction About three-quarters of all vinyl produced goes into long-lasting building and construction applications. Siding and Windows Vinyl helps produce siding and window frames that are extremely durable, affordable, and help conserve energy when heating and cooling homes. Dioxins are a class of chemicals unintentionally created from the manufacture and disposal of PVC products, such as vinyl flooring in schools.
According to the US EPA, the levels of dioxin-like compounds found in the general population may cause a lifetime cancer risk as high as one in 1, xxix. This is 1, times higher than the generally "acceptable" risk level of one in a million. Dioxin also causes a wide range of non-cancer effects including reproductive, developmental, immunological, and endocrine effects in both animals and humans xxx.
