Electrostatic charges may be generated during handling. Risk of self-ignition of bulk product above certain
temperature (Refer to Section 10). Specifically for powder grades and accumulated polymer dust: dust explosion
could occur.
Environmental Hazards:
No specific Hazards.

SECTION 4 FIRST AID MEASURES
Symptoms and Effects:
Not expected to give rise to an acute hazard under normal conditions of use.
Inhalation:
Remove to fresh air. If rapid recovery does not occur, obtain medical attention.
Skin:
If contact with hot material, cool the burn area by flushing with large amounts of water. DO NOT attempt to
remove anything from the burn area or apply burn creams or ointments. Cover the burn area loosely with a sterile
dressing, if available and seek medical attention.
Eye:
Flush eye with water. Seek medical attention if necessary.
Ingestion:
No specific measures.
Advice to physicians:
Treat Symptomatically.
SECTION 5 FIRE FIGHTING MEASURES
Specific Hazards:Not classified as flammable but will burn. Hazardous combustion products may include carbon
monoxide, carbon dioxide.
Extinguishing Media:
Foam, water spray or fog. Dry chemical powder, carbon dioxide, sand or earth may be used for small fires only.
Unsuitable Extinguishing Media:
Water in a jet may disperse fire.
Protective Equipment:
Full protective clothing and self contained breathing apparatus.
SECTION 6 ACCIDENTAL RELEASE MEASURES
Personal Precautions:
Avoid raising a dust cloud.
Environmental Precautions:
No Specific Measures.
Clean-up Methods - Small Spillage:
Shovel up and place in a labeled, sealable container for subsequent safe disposal as required by local, state,
federal, international or country specific regulations.
Clean-Up Methods - Large Spillage:
Transfer to a labeled, sealable container for product recovery or safe disposal as required by local, state, federal,
international or country specific regulations.
Protective Measures:
Wear appropriate personal protective equipment (refer to Section 8) when responding to spills.

Spill Management:
Shovel and sweep up or use industrial vacuum cleaner. Proper disposal should be evaluated based on regulatory
status of this material (refer to Section 13), potential contamination from subsequent use and spillage, and
regulations governing disposal in the local area. Prevent entry into waterways, sewer, or confined areas.
SECTION 7 HANDLING AND STORAGE
Handling:
Avoid generation or accumulation of dusts. Take precautionary measures against static discharges, earth/ground
all equipment. Avoid contact with heated or molten product. Do not breathe dust. Do not breathe fumes or
vapors from heated product. Use local exhaust extraction over processing area. Compounding of product in high
shear equipment can cause temperature to rise excessively if suitable cooling facilities are not available. In
Processing: Do not allow the temperature to exceed 230 deg. C (450 deg. F). A firewatch is recommended if
temperature exceeds 230 deg. C (450 deg. F).
Static charge buildup can be a potential fire hazard when used in the presence of volatile or flammable vapors or
in high airborne dust concentration. For more information, consult the KRATON Polymers Static Electricity Safety
Bulletin available from your sales representative.
Storage:
Keep container dry. Keep in a cool, well-ventilated place. Keep away from direct sunlight and other sources of
heat or ignition. Avoid storage of bulk product at temperatures above ambient to minimize risk of exothermic
degradation, self-heating and possible self-ignition (Refer to Section 10). Avoid storage under pressure or at
elevated temperatures to minimize particulate clustering. Do not stack intermediate bulk containers.
Storage Temperatures:
Ambient
Product Transfer:
Take precautionary measures against static discharge. Earth/Ground all equipment.
Other Information:
KRATON Polymer has a tendency to accumulate static charge during transport, handling and processing.
Reducing the velocity of material transfer will reduce the likelihood that charge will be created. Static charge
buildup can be a potential fire hazard when used in the presence of volatile or flammable vaors or in high airborne
dust concentrations. For more information, consult the KRATON Polymers Static Electricity Safety Bulletin
available from your sales representative.
SECTION 8 EXPOSURE CONTROLS/PERSONAL PROTECTION
Occupational Exposure:
None established. In the absence of occupational exposure standards for this product, it is recommended that
the following be adopted:
DUST, RESPIRABLE DUST
TLV (EH40)
Total Inhalable Dust: TWA (8 h) 10 mg/m3
Respirable Dust: TWA (8 h) = 4 mg/m3
RUBBER FUME
TLV (EH40)
RUBBER MANUFACTURING AND PROCESSING GIVING RISE TO RUBBER DUST AND RUBBER FUME
Rubber Fume: MEL/TWA (8 h) = 0.6 mg/m3
Rubber Process Dust: MEL/TWA (8 h) = 6 mg/m3
MEL = Maximum Exposure Limit

Engineering Control Measures: Use local exhaust ventilation.
Respiratory Protection:
Where local exhaust ventilation is not practicable and odors are detected use a negative pressure half face
respirator equipped with a cartridge designed to protect against organic vapors and if dust is also present a
particulate pre-filter should also be used. For high airborne dust concentrations use a cartridge designed to be
used against nuisance dust.
Hand Protection:
Cloth gloves if desired.
Eye Protection:
Dust-tight mono goggles
Body Protection:
Standard issue work clothes which may include: apron, safety shoes or boots as necessary.

SECTION 10 REACTIVITY AND STABILITY
Stability:
Stable under ambient conditions. Oxidizes exothermically above ambient temperature.
Conditions to Avoid:
Avoid contact with strong oxidizing agents. Accumulation of product in areas exposed to elevated temperatures
for extended periods in air may result in self-heating and auto ignition. Avoid elevated temperatures in storage for
prolonged periods of time (example: 5 days at 200 deg. F or 93 deg. C)
Hazardous Decomposition Products:
Hazardous vapors from heated products are not expected to be generated under normal processing temperatures
and conditions.
Although highly dependent on temperature and environmental conditions, a variety of thermal decomposition
products may be present if the product is over heated, is smoldering or catches fire. These range from simply
hydrocarbons (such as methane and propane) to toxic/irritating vapors (such as carbon monoxide and carbon
dioxide, acrolein, aldehydes and ketones). (Refer to Handling in Section 7).
