International Chemical Safety Cards POLYETHYLENE ICSC: 1488 Ethene, homopolymer Ethylene polymers PE HDPE LDPE (C2H4)n Molecular mass: Polymer, variable molecular mass ICSC #    1488 CAS #     9002-88-4 RTECS # TQ3325000 October 27, 2004 Peer reviewed TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. Powder, water spray, foam, carbon dioxide. EXPLOSION Finely dispersed particles form explosive mixtures in air. Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting. EXPOSURE  •INHALATION Cough. Avoid inhalation of dust . Fresh air, rest.  •SKIN Remove contaminated clothes. Rinse and then wash skin with water and soap.  •EYES Safety goggles. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Do not eat, drink, or smoke during work. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into suitable and labelled containers; if appropriate, moisten first to prevent dusting. Personal protection: P1 filter respirator for inert particles. Separated from incompatible materials . See Chemical Dangers. R: S: SEE IMPORTANT INFORMATION ON BACK ICSC: 1488 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994.

International Chemical Safety Cards POLYETHYLENE ICSC: 1488 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: WHITE SOLID IN VARIOUS FORMS PHYSICAL DANGERS: Dust explosion possible if in powder or granular form, mixed with air. CHEMICAL DANGERS: The substance decomposes on heating producing toxic fumes and irritating fumes , causing fire and explosion hazard. Reacts violently with fluorine. Reacts with strong acids , strong oxidants . OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK not established. ROUTES OF EXPOSURE: INHALATION RISK: A nuisance-causing concentration of airborne particles can be reached quickly especially if powdered. EFFECTS OF SHORT-TERM EXPOSURE: EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Melting point: (see Notes) 85-140°C Density: (see Notes) 0.91-0.96 g/cm3 Flash point: (see Notes) 341°C Auto-ignition temperature: (see Notes) 330-410°C ENVIRONMENTAL DATA N O T E S LDPE means Polyethylene with low density; HDPE means Polyethylene with high density. Physicochemical properties vary depending upon the molecular mass. Thermal degradation starts at 290°C. The PE products are available in large selection of various forms, due to additives used in the manufacture.The additives can influence the physical and toxicological properties of this substance.
