Product Name: Redispersible Polymer Powder
Common Trade Name: RPP
Recommended Use: Construction additives, tile adhesives, plasters
Manufacturer: Major chemical producers and distributors globally
Emergency Phone Number: Local emergency services or manufacturer hotline
Classification: Non-hazardous for the majority of applications but produces fine dust that may irritate airways
Main Risks: Respiratory irritation, eye and skin contact can trigger mild transient discomfort
Label Elements: Avoid breathing dust, wash hands after handling, ensure ventilation
Signal Word: None required under latest regulatory frameworks, but "Attention" helps remind workers
Health Concerns: Long-term exposures to dust can set off coughing spells or minor respiratory flare-ups
Chemical Nature: Copolymer of vinyl acetate and ethylene or acrylic-based powder
CAS Number: 24937-78-8 (for vinyl acetate/ethylene copolymers)
Typical Content: 80–95% copolymer, 3–10% anti-caking agents like calcium carbonate or talc, low levels of protective colloids or surfactants
Hazardous Components: Free monomer levels strictly minimized, usually well below occupational regulatory limits
Inhalation: Move to fresh air and help the person get comfortable. Remove exposure source if safe. Seek medical help if coughing or breathing problems persist.
Skin Contact: Wash with soap and water. Remove contaminated clothing. Irritation will resolve for most people with rinsing.
Eye Contact: Rinse eyes with plenty of running water for several minutes. Remove contact lenses if present.
Ingestion: Drink water to clear mouth. No serious effects expected, but seek medical attention if symptoms linger
Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide
Special Hazards: Fine dust can form explosive mixtures with air. Burning gives off carbon oxides and possibly traces of aldehydes
Protective Equipment: Firefighters need self-contained breathing apparatus and full protective gear
Specific Methods: Use water to cool storage and surrounding materials. Prevent contaminated runoff from entering sewers
Personal Precautions: Wear dust mask, goggles, and gloves. Ventilate area to control dust levels
Environmental Precautions: Sweep up spilled material to prevent it washing into drains, especially large spills
Clean-Up Methods: Collect into containers using methods that minimize dust. Use HEPA-filtered vacuum or damp sweeping for big jobs
Safe Handling: Avoid breathing dust. Keep containers closed. Use methods to reduce dust generation and exposure risk
Compatibility: Store away from strong oxidizers and sources of open flame
Storage Conditions: Cool, dry, and well-ventilated location, out of direct sunlight. Protect from moisture to keep powder free-flowing
Occupational Exposure Limit: Follow local regulations for nuisance dust, often set at 10 mg/m³ total dust, 3 mg/m³ respirable
Engineering Controls: Use local exhaust ventilation at points of dust generation
Protective Equipment: Dust masks meeting national requirements, close-fitting chemical safety goggles, gloves for frequent exposure
Hygiene Measures: Wash hands after use. Remove dusty work clothing before breaks or going home
Appearance: White or off-white free-flowing powder
Odor: Mild, slightly sweet or plastic-like
pH: 5–8 (in water dispersion)
Boiling Point: Not applicable, decomposes before boiling
Melting Point: Softening, not defined due to polymeric nature
Solubility: Insoluble in water, disperses with agitation
Bulk Density: 350–600 kg/m³
Ignition Temperature: Approximately 400°C and above
Particle Size: Most particles under 400 microns, designed for fast re-dispersion in water
Chemical Stability: Stable at room temperature and out of direct sunlight
Reactivity: Non-reactive under ordinary handling
Hazardous Decomposition: Combustion produces carbon monoxide, carbon dioxide, traces of formaldehyde/acetic acid
Conditions to Avoid: Open flame, strong oxidizing agents, moisture intrusion during storage
Acute Toxicity: Low, with no evidence of systemic effects in animal tests of vinyl acetate-based copolymers
Routes of Exposure: Inhalation of dust, skin and eye contact
Irritation: Dust can cause short-term coughing or mild irritation of airways, minor eye or skin irritation for sensitive individuals
Chronic Toxicity: No significant data showing chronic health effects, but long-term high-level workplace dust exposure should be limited
Carcinogenicity: No ingredients listed as carcinogenic by IARC, NTP, or OSHA
Ecotoxicity: Not classified as environmentally hazardous. Large releases can add suspended solids to waterways, potentially impacting aquatic life in high concentrations
Biodegradability: Polymer components break down slowly in the environment, with mineral fillers remaining stable
Bioaccumulation: Rapid uptake in biological organisms unlikely
Persistence: May remain in soil or sediment, but does not pose high risk
Waste Handling: Dispose of spilled or surplus powder according to local regulations, usually as non-hazardous industrial waste
Recycling: Uncontaminated powder can sometimes be reused in compatible manufacturing processes
Incineration: Approved facilities can handle small quantities safely, ensuring proper off-gas treatment
Packaging: Empty packaging may be sent for recycling if residues are carefully cleared
UN Number: Not regulated as a dangerous good
Transport Hazard Class: None, considered safe for normal conditions
Proper Shipping Name: Redispersible Polymer Powder
Packing Group: Not applicable
Environmental Hazards: None, but avoid significant dust emissions or spills that could cause slip hazards
Regulatory Status: Not classified as hazardous under GHS, EU CLP, US OSHA HCS or similar systems
Safety Reporting: Workplace dust controls, labeling, and routine employee training are still expected
Inventory Status: Listed in major chemical inventories (TSCA, EINECS/ELINCS, ENCS, AICS)
Other Requirements: Compliance with occupational exposure, transport, and environmental rules is necessary wherever the powder is handled, used, or disposed
