1. Product Overview

2. Composition

3. Physical and Chemical Properties

3.1 Basic Properties

• Appearance: Colorless or yellow transparent liquid; yellow or light yellow (typical value).

3.2 Free Foam Parameters

3.3 Physical Properties

4. Hazard Identification

• Eyes: Slight irritation to eyes.
• Skin: Long-term or repeated contact generally does not cause skin damage (except for allergic individuals). Avoid contact if skin is damaged (e.g., scratches, abrasions). Contact with the material when heated at high temperatures may cause skin burns.
• Ingestion: Contains small amounts of amine catalysts; ingestion is harmful. Small amounts, with proper first aid, may not cause harm, but large amounts can be harmful.
• Inhalation: Inhaling vapors of fluorocarbons (e.g., 1,1-dichloro-1-fluoroethane) can affect the nervous system, causing rapid anesthetic effects. Large inhalation may accelerate heartbeat, disrupt regular heartbeats, and damage heart function. Excessive exposure can damage the central nervous system, leading to anesthetic symptoms.

5. Safety Measures

5.1 First Aid

• Eyes: If splashed, immediately rinse with plenty of water; continue rinsing after removing the material. Seek medical attention if necessary.
• Skin: Remove contaminated clothing and shoes, rinse skin with soap and plenty of water. Seek medical attention if adverse reactions occur.
• Ingestion: Seek medical attention immediately; do not induce vomiting unless instructed by a professional.
• Inhalation: Move to fresh air. Seek medical attention if severe.

5.2 Fire-Fighting Measures

• Hazardous combustion products: Incomplete combustion decomposes into harmful gases at high temperatures; complete combustion produces carbon oxides, nitrogen oxides, water vapor, ammonia, hydrochloric acid, etc. It is combustible and may aid in fire or explosion.
• Extinguishing media: Carbon dioxide, dry powder, foam. Do not use direct water jets as they may spread the flame; use mist water if no other media are available.
• Fire-fighting instructions: Evacuate people, isolate the fire area, stay upwind, and prohibit non-related personnel from entering. Avoid low-lying areas where harmful gases may accumulate. Cool containers and surrounding areas with water during fire fighting; transfer threatened barrels if safe.
• Protection for firefighters: Wear pressure self-contained breathing apparatus and fire-resistant clothing (helmet, coat, pants, gloves, boots).

5.3 Leakage Handling

• Small leakage: Rinse with water.
• Large leakage: Contain and recover; clean contaminated ground with water or detergents. Disposal of waste materials must comply with local environmental regulations.

6. Handling and Storage

6.1 Handling

• Polyols react with isocyanates; clearly distinguish and avoid contact to prevent uncontrollable reactions.
• Barrels containing the material are under pressure; avoid open flames, piercing, collision, or impact.
• Used in multi-component rigid polyurethane foam board continuous or batch lines. Check and calibrate flow delivery and mixing pressure of each component before use. During use, the temperature of laminator chain plates is preferably 60-70℃, and the temperature of upper and lower clean steel plates is 35-45℃. Corona treatment on upper and lower steel plates and glue spraying on lower steel plates are required before pouring; discharge temperature is 28-32℃.

6.2 Storage

• The material is hygroscopic; keep barrels tightly sealed.
• Store in a ventilated, cool place at 5-35℃, away from direct sunlight. Avoid long-term storage above 40℃ to prevent excessive volatile loss of foaming agents and performance degradation.

7. Exposure Control and Personal Protection

• Engineering controls: Ensure adequate ventilation.
• Eye/face protection: Wear goggles; use full face protection (goggles and mask) if vapors cause discomfort.
• Skin protection: Wear impermeable gloves and long-sleeved clothing. Clean with soap before eating, drinking, or smoking after work. Contaminated clothing must be cleaned and dried before reuse or disposed of harmlessly.
• Respiratory protection: Generally not required. Use respiratory protection in poorly ventilated, high-temperature environments or where atomized particles are present.

8. Stability and Reactivity

• Chemical stability: Stable under recommended storage conditions.
• Conditions to avoid: Storage above recommended temperatures may increase barrel pressure; avoid direct sunlight and open flames.
• Incompatible substances: Oxidizing agents, strong acids, isocyanates.
• Hazardous decomposition/polymerization: No hazardous decomposition under normal use and storage; no polymerization.

9. Ecological Information

• The physical foaming agent is HCFC-141b, with ODP=0.11 and GWP=300 (CO₂=1).
• Polyols are not easily biodegradable in strict experiments, but the material may undergo biodegradation under environmental conditions. Avoid release into water or soil.

10. Transportation and Packaging

• Packaging: 200L green steel barrels; 200kg/barrel.
• Comply with relevant transportation regulations.

11. Other Information

• Shelf life: 6 months under appropriate storage conditions; can be used after passing inspection if exceeded.
• Usage notes: Test before formal use to ensure suitability for specific production processes. The provided data are typical test values, which may vary slightly with environmental conditions and have no legal binding force.
