Polyether Polyol XS-3445
Description
XS-3445 polyol is a kind of rigid polyether polyol initiated with toluene diamine. It has quite good miscibility with cyclopentane, used in cyclo-/iso-pentane blown systems. The rigid products have better inflexibility and heat-insulated performance than other general rigid polyols.
Typical Properties
| Appearance | Brownish red viscous liquid |
| Hydroxyl number (mgKOH/g) | 450±20 |
| Water (%) | ≤0.15 |
| Viscosity at 25℃ (mPa.s) | 8000±2000 |
Applications
XS-3445 polyol is mainly used in PU rigid systems, involving the fields of refrigerated equipments in food industry, heat-insulated slabs, piping insulation, auto spare parts and synthetic-wood etc.
Storage and Supply
XS-3445 polyol is slightly hygroscopic and may absorb moisture, which would affect the properties of the products. The polyol should be stored in sealed containers and in dry conditions, away from direct sources of heat. Polyol is supplied in drums and tank trucks; or confer with supplier.
Health and Safety Information
XS-3445 polyol has a very low odor 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 and Explosion
