Chemical Resistance

Insulock PVC Cladding has excellent chemical resistance to most commercial chemicals and is suitable in most wash down situations. They are resistant to most industrial fumes, humidity conditions, salt water and adverse weather.

The effect of chemical attack on PVC is substantially different than the effect on metals, which is known as corrosion. Metallic corrosion means the slow wearing away by chemical or electrolytic action. Scratches or surface abrasions on PVC do not provide sites for corrosion attack. Chemical attack on PVC is indicated by swelling and dissolving. Swelling normally precedes dissolving and alters the properties of the PVC.

Insulock PVC fitting covers and jacketing, unlike metals are inherently immune to galvanic or electrolytic action. They can be used in the presence of metals and can be connected to other materials used for insulation around metals.

Insulock fitting covers and jacketing are non sparking, and therefore safe wherever flammable or explosive materials and atmospheres are involved. They are non-toxic, odourless and tasteless. These facts are important when used in the food, beverage and pharmaceutical industries.

Chemical resistance chart data is based on total immersion of the PVC in the chemical named. Corrosion of the PVC due to fumes from the chemicals in the atmosphere is much less pronounced in most cases.
