Inhalation: Remove from area to fresh air; seek medical attention if persistent cough, wheezing, or other symptoms occur
Skin Contact: Wash thoroughly with mild soap and running water; remove contaminated clothing
Eye Contact: Rinse with gentle stream of water for at least 15 minutes; consult physician if irritation persists
Ingestion: Rinse mouth, seek immediate medical advice; do not induce vomiting unless directed by healthcare provider
Notable Symptoms: Dust may cause short-term redness, itching, or slight rash
Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam, water fog
Unsuitable Extinguishing Media: Direct water stream on molten product
Specific Hazards: In extreme heat, decomposes to release hydrogen chloride and oxides of carbon
Protective Equipment: Self-contained breathing apparatus, complete firefighting gear, avoid inhaling smoke or fumes
Special Precautions: Cool containers exposed to fire with water spray; avoid runoff containing product residues
Spill Response: Sweep or vacuum up spilled material; avoid creating dust clouds
Environmental Precautions: Prevent runoff into storm drains or natural waterways
Cleaning Methods: Dampen powders to reduce airborne loss, place in clearly labeled closed containers for safe disposal
Personal Precautions: Use respiratory protection if cleaning large spills indoors; wear gloves and goggles
Waste Handling: Comply with local physical and chemical waste regulations
Safe Handling: Use in well-ventilated area to minimize dust; avoid contact with open flames or hot surfaces
Storage Conditions: Keep resin in dry, cool, ventilated place, away from direct sunlight and incompatible chemicals
Incompatibles: Strong acids, strong oxidizing agents, alkaline substances
Packaging Requirements: Use moisture-resistant, sealed containers to protect from humidity
Specific Practices: Rotate stock to avoid aging, ensure easy access for inspection
Exposure Limits: No established occupational threshold limits for base resin, but minimize exposure to dust; ACGIH recommends minimizing nuisance dust inhalation
Engineering Controls: Local exhaust or general ventilation to keep airborne concentrations low
Personal Protection: Wear safety glasses, dust mask (respirator with P2 filter for major spills), gloves made of PVC or nitrile
Hygiene Measures: Wash hands after handling and before meals, avoid eating or smoking in active work area
Environmental Controls: Capture dust and wastes at source for environmentally responsible disposal
Appearance: White, off-white, or lightly colored granules or powder
Odor: Faint, characteristic odor; not intense
pH: Neutral to slightly acidic in dispersion
Melting Point: Softening noticeably above 130°C, not a sharp melting point due to polymeric nature
Boiling Point: Not applicable (thermoplastic polymer)
Flash Point: Above 200°C (resin non-flammable under standard conditions)
Solubility: Insoluble in water; swells or dissolves in select organic solvents
Vapor Pressure: Negligible at room temperature
Density: 1.30 – 1.40 g/cm³
Partition Coefficient: Not applicable due to polymer structure
Chemical Stability: Stable under recommended storage and handling conditions
Polymerization: Not expected under normal use
Hazardous Decomposition: Releases hydrogen chloride and carbon oxides at temperatures above 180°C; avoid processing above this point
Reactivity: Not reactive with most common materials; effective as formulated for intended industrial use
Incompatible Materials: Strong acids or alkalis, oxidizers can break down resin integrity
Acute Toxicity: No evidence of acute oral or dermal toxicity at common levels
Skin Irritation: May cause mild, temporary irritation with prolonged skin contact
Eye Contact: Particles can cause short-lasting discomfort and redness
Respiratory Exposure: Dust inhalation may provoke minor respiratory tract irritation; no systemic toxicity documented in workplace studies
Sensitization: Not classified as a skin or respiratory sensitizer
Chronic Effects: No confirmed harmful effects for typical workplace exposure
Ecotoxicity: Inert polymer expected to pose low hazard to aquatic and terrestrial life
Persistence/Degradability: Slowly degrades in natural environments; not readily biodegradable
Bioaccumulation: Significant accumulation in living tissue unlikely
Mobility: Sinks in water; low risk of widespread released contamination
Aquatic Impact: Insoluble solids may impact sediment, but without known chronic toxicity
Waste Treatment Methods: Dispose as non-hazardous polymer resin in accordance with local, regional, and national regulations
Sewage Disposal: Do not wash down drains; collect and segregate solid waste for controlled disposal
Recycling Potential: Industrial resins can be reused or repurposed in compatible product streams
Incineration: Incinerate using proper scrubbing equipment to handle hydrogen chloride release
Packaging Waste: Clean, empty packaging may be recyclable; otherwise, treat as solid industrial waste
UN Number: Not regulated for ground, air, or sea transport
Packaging Group: Not assigned
Hazard Class: Resin is not a classified transport hazard; keep bags and containers tightly closed, use clean, dry vehicles
