Polyester cut flock safety data sheet
Trade name: Polyester (PES) Cut Flock
1. Identification of substance/preparation and company/undertaking
Producer and supplier:
2. Composition / information on ingredients
Cut fibres with diameters of 10 mm (1 dtex) to 45 mm (22 dtex) and mean length of 0.3 to 3.0 mm. Raw white, spundyed or bath dyed.
Preparation on the fibre: inorganic and organic chemicals (total amount max. 0.5 % of weight) which are indispensable for Flock quality intended for electrostatic flocking.
Flock black spundyed contains about 2.5 % of black pigment = Carbon Black (CI 77266)
3. Hazards identification
To the best of our knowledge, Polyester flock products have not been associated with negative effects on humans if used in accordance with good industrial hygiene practice and any legal requirements.
Fine dust fibres: with the above mentioned dimensions, all Cut Flock Products of SwissFlock Inc. are above the dimensions of „Fine Dust Fibers“ which have been defined as follows *) :
Diameter < 3 mm, length 5 - 100 mm, proportion length : diameter > 3 : 1

4. First-aid measures
Inhalation: Not specifically concerned (s. pt 3)
Skin contact: Not specifically concerned
In case of fire, the molten product may cause burns. Rinse with plenty of water. Do not attempt to remove clothes (danger of adherence to the skin). Call for a physician.
Eye contact: Not specifically concerned
Ingestion: Not specifically concerned
5. Fire-fighting measures
Fire extinguishing agents:
Restrictions: No restrictions
Specific information for fire-fight: Use autonomous respirators to fight fire indoor or in poorly ventilated areas. Do not use water as extinguishing agent in the presence of uninterrupted electrical installations. Hazardous decomposition products: Depending on temperature and oxygen availability, combustion off-gases contain variable quantities of toxic substances ( carbon monoxide, acetaldehyde, various organic compounds) which must not be inhaled.
6. Accidental release measures
7. Handling and storage
Storage: No special safety precautions
Storage conditions: Consider technical advices referring to optimal processability
8. Exposure controls and personal protection
Components with occupational exposure limits: none
Personal protection: Dust mask, protecting goggles
9. Physical and chemical properties:
Appearance: Form: short fibres
Colour: raw white or dyed
Melting range: [°C]: 250-260
Flash point: [°C]: 350 - 400
Ignition temperature: [°C]: about 420
Thermal decomposition: [°C]: starts at about 350
Explosion limits: Cut Flock / air mixtures may be explosible within certain concentration limits and sufficiently high ignition energies (dust explosion class 1, Kst-value >0 to 200 bar*m*s-1). Electrostatic flocking installations with an electric discharge energy > 500 mJ show a lower explosion limit of > 125 g Flock / m3 of air. S. Journal „Flock“, Dec. 1983, p. 4 - 10
Density: [g/cm3]: 1.38 - 1.42
Apparent density: [kg/m3] 80 - 200
Vapor pressure: not applicable
Solubility in water: Flock products are not water soluble
10. Stability and reactivity
Conditions to avoid: none under normal storage conditions
Materials to avoid: none under normal storage conditions
Hazardous decomposition products: none under normal storage conditions
Combustion off-gases see point 5.
11. Toxicological information
The fibre product does not present special risks on humans if used in accordance with good Industrial hygiene practice and the concerning legal requirements.
In case of special end uses, SwissFlock Inc. may be contacted for additional information.
12. Ecological information
The fibre product is not associated with ecological problems, provided that the wastes are orderly disposed of.
Because of its chemical nature, the product is not ecotoxic and not readily biodegradable.
13. Disposal considerations
Can be disposed of as solid waste or burned in suitable installations, subject to local regulations.
14. Transport information
Class RID/ADR: not classified as hazardous
Class ICAO/IATA: not classified as hazardous
Class OMI/IMDG: not classified as hazardous
15. Regulatory information
Classification and labeling
16. Other information
This Safety Data Sheet uses the format and listing sequence of Commission Directive 91/155/EEC though the described product is not a dangerous preparation. It is intended to inform about physical properties, safety aspects, toxicological data and ecological characteristics that are relevant for the use of synthetic fibres in textile, technical and industrial applications, and to recommend procedures for their handling, storage and transport.
This Safety Data Sheet is a complement to Technical Data Sheets but does not replace them. The information given is to the best of our knowledge at the date of issue. It does not constitute a contractual description of product properties.
The Safety Data Sheet is not meant to be handed out to private end-users.
The Safety Data Sheet does not disengage the user of his duty to know and to apply any law and reglulation that may be relevant.
Additional information may be requested at SwissFlock Inc. if special applications of synthetic fibres are intended.
Taking fiber based raw material and giving it a life of it's own has been the cornerstone of development at Swissflock.
