FAQs
Common Questions about Polyurethane Material Safety
Yes. You can download the ML6® Polyurethane Safety Data Sheet below for complete handling, storage, and safety information.
ML6® polyurethane is a thermoset polyurethane, meaning it cannot be re-melted or reshaped. It is not recyclable, but its durability often reduces replacement frequency and total environmental impact.
Yes. ML6® polyurethane has excellent resistance to many oils, solvents, and chemicals. However, chemical compatibility varies, please contact us with your specific environmental conditions for evaluation.
Certain ML6® polyurethane formulations are certified for FDA or direct food contact applications. For food-grade polyurethane applications, please contact our engineering team to discuss your specific requirements..
No. ML6® polyurethane is classified under Export Administration Regulation (EAR99). This designation means it is not specifically listed on the Commerce Control List (CCL) maintained by the U.S. Department of Commerce’s Bureau of Industry and Security (BIS). As such, ML6® can typically be exported to most destinations without an export license, provided:
The end use is not for a prohibited purpose (e.g., weapons of mass destruction).
The end user is not on any U.S. Government restricted or denied party lists.
The destination is not subject to comprehensive U.S. sanctions or embargoes (e.g., Cuba, North Korea, Iran, Syria, or certain regions of Russia).
ML6® is a non-hazardous, non-dual-use industrial material and does not contain any components subject to additional export restrictions under ITAR or EAR controls. As always, exporters are responsible for screening transactions to ensure full compliance with all applicable export laws and regulations.
ML6® polyurethane is REACH Compliant. Meridian Laboratory exports less than 1 metric ton of material per year to the EU, making registration unnecessary.
Yes. ML6® polyurethane meets the requirements of California Prop 65 and does not contain any listed substances known to cause cancer or reproductive harm.
No. ML6® polyurethane is a polymer formed from organic compounds and contains no lead or other heavy metals.
Yes. ML6® polyurethane is fully RoHS compliant and tested to confirm the absence of hazardous substances, including Lead (Pb), Cadmium (Cd), Mercury (Hg), Hexavalent Chromium (Cr VI), PBBs, and PBDEs.
Yes. ML6® polyurethane is classified as a non-hazardous, non-recyclable material and can be disposed of with standard industrial or municipal waste, in accordance with local regulations.

Polyurethane elastomers are fully reacted polymers forming Articles which are not considered hazardous under osha’s Criteria 29 cfr 1910.1200. However, hazardous dusts, vapors, gases, or fumes may be released by mechanical or thermal processing, or by thermal decomposition.
Section 3: Hazard Identification
Emergency Overview
Acute: Fumes from hot wire cutting can be irritating and lead to coughing. These fumes could contain traces of tdi, mdi, other isocyanates, and/or curatives. Skin or airborne exposure to isocyanates may produce an asthma-like lung sensitization, with shortness of breath, wheezing or cough, which may occur after re-exposure to very low levels.
Skin contact with some polyurethane products may result in skin sensitization or an asthma-like lung sensitization.
Chronic: Animal studies indicate that chronic inhalation or overexposure of dusts may cause inflammation of the lungs, fibrosis, and airway destruction.
Severe Immediate Hazards:
Dusts from grinding operations may aggravate existing lung disorders when proper protection is not used.
Potential Health Effects:
| Routes of Exposure: | x Skin | x Inhalation | |||
| o Ingestion Lengths of Exposure: | o Single | x Repeated | |||
| x Lifetime Severity of Effect: | o Mild | o Moderate | x Severe | ||
| Target Organs: | o Liver | o Kidney | x Lung | x Skin | o______ |
See acute and chronic effects in Emergency Overview.
Carcinogenity
Cured polyurethane is not listed as a carcinogen

Procedures
Flush eyes with water if dust from grinding causes irritation.

None
Section 5: Fire Fighting Measures
Flammable Properties
| Flash Point: | Not Applicable | |
| Flammable Limits: | LEL: Not Applicable | UEL: Not Applicable |
| Dusts from processing operations may be combustible. |
Extinguishing Media
Water, dry chemical, foam, or carbon dioxide.
Fire Fighting Instructions
Evacuate non-emergency personnel to a safe area. Firefighters should use selfcontained breathing
apparatus. Avoid breathing smoke, fumes, and decomposition products. Use water spray to quench
smoldering elastomers. Product may melt after ignition, toform flammable liquids. Burning produces
intense heat, dense smoke, and toxic gases, such as isocyanates, carbon monoxide, oxides of nitrogen, and
traces of hydrogen cyanide. Do not breathe smoke. Smoke released, even after fire is out, may contain high
concentrations of isocyanates hundreds of feet away. Do not remove self- contained breathing apparatus
until smoke is gone and area is completely ventilated with clean air.
Section 6: Accidental Release Measures
Safeguards (Personal)
None
Spill Clean Up
Pick up and handle as any other solid material.
Section 7: Handling and Storage
Handling
Cutting elastomer by hot wire or hot branding, or other thermal processing can form decomposition
products. Local exhaust ventilation should be used to remove any fumes. If isocyanates or curatives are
emitted, ventilation must be sufficient to ensure levels below the TLV for TDI (0.005 PPM TWA/0.02 PPM
STEL), MDI (0.005 PPM TWA), other isocyanates, or curatives. Also, see respiratory protection below.
Storage
Store elastomers in areas equipped with sprinkler systems. Store away from sparks, flames, or other ignition
sources.
Section 8: Exposure Controls, Personal Protection
Engineering Controls
Local exhaust recommended for thermal processing operations, as required to reduce dust, gas, and vapor
fume exposure below OSHA levels.
Personal protective Equipment
Eye/Face Protection: None required in normal use. For grinding operations, use safety goggles, and face
shield.
Skin Protection
None required in normal use.
Respiratory Protection (specify type)
Use NIOSH approved respirator. For grinding operations – wear a dust respirator. If generating gas, vapor,
and fumes from hot wire, hot knife, or other thermal processing operations – wear an air-purifying respirator
with organic cartridge or supplied-air respirator if ventilation is inadequate.
General Protection
None required.
