Handling
The polyethylene exterior of the product does not present a handling problem.
Engineering Controls
Good general ventilation of workshops is essential to minimise the concentration of fumes.
Skin Protection/Hygiene Measures
Postsaver should not normally cause skin irritation. Plastic or rubber gloves are recommended for prolonged
contact.
Hands should be washed after handling boots and before eating, using lavatory and at the end of the day.
Physical State at Ambient Temperature
Solid.
Colour
Black.
Odour
Polyethylene. Bitumen characteristic.
Melting Point
Polyethylene 90-130ºC, (190-266ºF).
Flash Point
Greater than 220ºC, (428ºF), for bitumen and greater than 340ºC, (644ºF), for polyethylene film.
Auto Ignition Temperature
Greater than 300ºC, (572ºF), for bitumen and greater than 400ºC, (752ºF), for polyethylene film.
Solubility
Postsaver is insoluble in water.
Solubility in Organic Solvents
In general the outer polyethylene layer is insoluble in organic solvents. Prolonged immersion in aromatic
hydrocarbons and/or n-paraffins can cause swelling at room temperatures and dissolving at higher
temperatures. The inner bitumen layer is partially soluble in fat and soluble in most organic solvents.
Chemical and Thermal Stability
Postsaver boots are stable under normal handling and storage conditions. If stored continuously in direct
sunlight or excessive temperatures, above the recommended storage and handling temperatures, the boots will
start to shrink, the bitumen lining will crack and will give off flammable vapours.
Hazardous Decomposition Products
Burning product will give off a complex mixture of gases including carbon dioxide, carbon monoxide, sulphur
oxides and thick dense smoke.
Ingestion
The toxicity from ingestion of this product is minimal, however some breathing difficulties or choking may occur
if swallowed.
