Applications
YUKOL 3553 polyol is specially designed for the manufacture of high resilience slabstock and mold foams for automotive and furniture applications. Other uses include semi-rigid foams, instrument panel core foams, integral skin foams, etc. with or without polymer polyol, YUKOL 3553 polyol can be formulated to meet customer requirements, and processing conditions against a wide verity of isocynates.
Storage
YUKOL 3553 polyol is hygroscopic and absorption of moisture would affect polyol reactivity and physical properties of the resulting polymer. The material should be stored in sealed containers and in dry conditions, away from direct source of heat. The recommended storage temperature is between 20 ~ 35°C.
Handling Precautions
YUKOL 3553 polyol has a very low order of acute toxicity and does not present a significant health hazard to users. Normal standards of industrial hygiene should however be observed when handling this chemical. Suitable protective clothing and eye protection must be worn to avoid unnecessary contacts and accidental ingestion. In case of eye contact, seek medical attention.
Fire & Explosion Hazards
YUKOL 3553 polyol is not readily ignited, but like most organic materials, it will burn when involved in a fire.
