Standard range of sealblend fillers are as follows:-

V - range:	Expanded cross-linked polyethylene.
N - range	Expanded cross-linked polyethylene.
N range fr	Expanded cross-linked polyethylene with fr additives.
R1025	E.P.D.M synthetic rubber.
R5025	E.P.D.M synthetic rubber.
RF25	E.P.D.M on expanded cross-linked polyethylene.

POTENTIAL HAZARDS:

Toxicity:
Materials are chemically un-reactive and tests have demonstrated that they are biologically inert.

Inhalation:(fume evolution):
There is no release of any noxious fumes from sealblend fillers at ambient temperature.

Ingestion:
Ingestion of sealblend fillers should be avoided although the materials are inert and can be regarded as toxicologically harmless except for some flame retardent grades containing additives which could be harmful if swallowed.

Physical contact:
Materials used in the manufacture of sealblend fillers are considered not to be skin irritants, but since the basic polymers for P.E fillers are fairly hard, under some circumstances they can have a minor abrasive affect on skin. Particles of foam may cause physical irritation if they get into the eyes. No cases of allergic reaction to materials used in the manufacture of P.E fillers have been confirmed in over 20 years of use. Some people, however, have an allergic reaction to rubbers of all types, which may therefore apply to EPDM fillers, but these circumstances are rare.

Fire, ignition and burning characteristics:
When P.E fillers are heated in air, softening will occur at 105-115 deg C and decomposition will occur at about 300 deg C. Above this temperature the materials will pyrolyse oxidatively to produce carbon monoxide and water, plus small amounts off various hydrocarbons and aldehydes. The evolved gasses may ignite, and if they do they will provide heat of combustion pyrolysing more foam than other materials in the vacinity. Under flaming conditions the main combustion products are carbon dioxide and water, although if insufficient oxygen is present, or when the flame is extinguished, the smoke may contain appreciable quantities of carbon monoxide, acrolein and other aldehydes. Burning can be accompanied by the release of flaming molten droplets of polymer which could ignite adjacent flammable materials. The flame retardent grade contains toxic additives designed to reduce the ignitability and flame spread from small heat sources. In a full scale fire these materials can burn to give dense black smoke and acrid fumes. When EPDM is heated, surface degradation will take place above 160 deg. C after various periods of time, and will pyrolyse at about 300 deg. C producing carbon monoxide, small amounts of hydrocarbons and solid particulate matter. The evolved gasses may ignite and, if they do, will provide heat of combustion, pyrolysing other material in the vacinity.

These comments can only be of general nature since the conditions of a real fire cannot be fully predicted.

Fire:
Action in the event of a fire involving plastazote foam.
Any commonly available fire extinguisher may be used. Water, particularly in the form of a spray, has been found to be very effective but may be inadvisable in certain circumstances; e.g. in close proximity to electrical installations. It is recommended that advice should be sought from the local fire authority on fire fighting equipment and procedures.

RECOMMENDED FIRST AID TREATMENT:

Eye injuries:
Any material entering the eye should be flushed with copious quantities of water. Medical attention should be obtained if soreness or redness persists.

Inhalation of fumes (from overheated materials):
An affected person should be removed as quickly as possible into fresh air, kept warm and artificial respiration applied as necessary. Medical attention should be obtained immediately.

Burns:
Any molten material on the skin should be cooled as quickly as
possible: e.g in cold water, but should not be pulled off. Medical attention should be obtained immediately.
Ingestion:
rinse mouth with water and obtain medical attention.

Nasal and aural:
If small sections of plastazote foam become lodged in the passages of the ears or nose. Medical attention should be sought for their removal.

Medical attention:
It is important that medical staff involved should be advised of the nature of the material being handled and its likely decomposition products.
