Product Name: Natural Rubber
Chemical Name: Polyisoprene
Chemical Formula: (C5H8)n
Other Names: Latex Rubber, India Rubber, Gum Rubber
Recommended Use: Tires, footwear, adhesives, rubber goods
Supplier Details: Provided by commercial supplier or manufacturer on shipment
Emergency Number: Provided by local regulatory authority or supplier
Hazard Classification: Not classified as hazardous under GHS for intact solid but latex form can cause allergic reactions
Routes of Exposure: Skin contact, inhalation of dust or vapor, eye contact in processing
Health Hazards: Allergic skin reactions, respiratory allergies (mainly from proteins in latex)
Physical Hazards: Combustible, can produce smoke in fire
Environmental Hazards: Not identified as major environmental toxin but slow to degrade
Label Elements: Warning: Possible sensitizer, keep away from flames
Main Ingredient: Cis-1,4 Polyisoprene 92–94%
Non-Rubber Substances: Proteins, fatty acids, sugars, resins (natural presence)
Additives (if processed): Antioxidants, stabilizers (concentration depends on grade and formulation)
Impurities: Small amounts of naturally occurring non-rubber plant constituents
Inhalation: Move affected person to fresh air if exposed to smoke or dust, seek medical attention for persistent irritation
Skin Contact: Wash area with soap and water, remove contaminated clothing, seek medical care if rash develops
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present, get medical advice if irritation persists
Ingestion: Unlikely route for rubber, seek medical attention if large amount ingested
Note for Physician: Treat symptomatically, watch for allergic reactions especially among sensitive individuals
Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide
Unsuitable Media: Avoid direct water jet as it can spread hot molten rubber
Specific Hazards: Dense black smoke, carbon monoxide, carbon dioxide, irritating fumes
Protective Equipment: Full protective gear, self-contained breathing apparatus
Firefighting Instructions: Cool adjacent containers, avoid inhaling fumes, keep out of downwind area
Personal Precautions: Wear gloves, eye protection, avoid dust inhalation during cleanup
Spill Cleanup: Collect solid material manually, sweep up, place in suitable waste containers for disposal
Environmental Precautions: Prevent entry into drains and watercourses, contain spills on soil for later removal
Disposal: See Disposal Considerations for suitable instructions
Safe Handling: Avoid creating dust when cutting or shaping, minimize skin contact for latex-sensitive personnel, work in well-ventilated place
Storage Conditions: Store in cool, dry, well-ventilated area away from direct sunlight and strong oxidizing agents
Storage Materials: Store in original containers or lined bins, avoid contact with copper and manganese products
Special Precautions: Use appropriate anti-static measures in dusty environments, limit storage of large stocks near ignition sources
Occupational Exposure Limits: None specifically for bulk natural rubber, latex exposure guidelines in some jurisdictions
Engineering Controls: Local exhaust ventilation for dust or aerosol-generating processes
Personal Protective Equipment: Protective gloves (nitrile or equivalent for latex-sensitive), safety goggles, dust mask or respirator where dust or fumes arise
Hygiene Measures: Wash hands after handling, do not eat, drink, or smoke in work area, remove contaminated clothing
Appearance: Pale or off-white to light brown solid or milky white liquid (latex form)
Odor: Slight, characteristic rubbery
Melting Point: Softens above 30°C, decomposition above 200°C
Boiling Point: Not applicable (decomposes)
Solubility: Insoluble in water, soluble in some organic solvents (e.g., chloroform, benzene)
Density: ~0.92 g/cm3 (solid)
Vapor Pressure: Not applicable
pH: Neutral (solid), slightly alkaline in fresh latex
Other Properties: Elastic, tensile strength varies by grade
Chemical Stability: Stable under normal temperatures and pressures
Hazardous Polymerization: Does not occur
Incompatible Materials: Strong oxidizers, copper alloys, manganese
Decomposition Products: Under fire: carbon monoxide, carbon dioxide, irritating organic fumes
Reactivity: Can degrade with prolonged exposure to sunlight, ozone, or high heat
Routes of Exposure: Skin, inhalation, rarely ingestion
Acute Toxicity: Not acutely toxic as bulk product
Sensitization: Known to cause allergic reactions in sensitive individuals (latex proteins)
Chronic Effects: Repeated skin exposure can lead to eczema or dermatitis in allergic persons
Carcinogenicity: Not listed by IARC, OSHA, or NTP as carcinogen
Other Data: No evidence of reproductive toxicity or mutagenicity from bulk material
Eco-toxicity: Not considered toxic to aquatic or terrestrial life in natural state
Persistence: Naturally biodegradable, though process takes months or years
Bioaccumulation: Not expected to bioaccumulate
Mobility: Not mobile in solid state, may settle in water bodies
Degradation Products: Co2, water, trace organic acids as it breaks down
Waste Treatment Methods: Commercial recycling where facilities exist, energy recovery by approved incineration
Landfill Disposal: Permitted for non-hazardous municipal waste, recommend cutting into smaller pieces
Special Precautions: Avoid burning in open air, do not dispose in waterways
Contaminated Packaging: Clean and recycle where possible, otherwise dispose as per local regulations
UN Number: Not regulated
Transport Hazard Class: Not hazardous under ADR, IMDG, or IATA
Packing Group: Not assigned
Special Transport Precautions: Protect from direct sunlight and moisture, avoid compressing or dropping bales during handling
Labeling Requirements: No specific marking for ground, air, or sea transport
Workplace Regulations: Ensure compliance with OSHA, EU REACH, or local worker protection laws regarding allergy hazards
Environmental Regulations: Not subject to RCRA or CERCLA listing for hazardous waste
Labeling/Warning: Latex allergy notification often required in some jurisdictions for products containing natural rubber latex
Chemical Inventories: Listed on TSCA, EINECS, DSL, and other international chemical inventories
Additional Regulation: Comply with packaging, labeling, and allergy notification rules as per all relevant government guidelines
