::: What we offer >> Rigid Polyurethane Foam
 
Rigid Polyurethane Foam
Rigid polyurethane (PUR) foam shows its versatility through excellent chemical and physical properties, both of which enable it to be used in a wide variety of multi-functional building and structural products which have high demand for insulation. Rigid polyurethane foam boasts for its low thermal conductivity, high shear strength, excellent processability, high chemical resistance, adjustable flame-retardance, good adhesion, etc.
Our PUR foam products range from PUR foam system to PUR panels (including continuous moulding panels )

JY series rigid polyurethane foam system
Introduction
They are mixed by polyol, blowing agent, catalyst, additives at optimum ratio, directly used in on-the spot foaming. The raw material has good fluidity and finished foam products have uniform density, high strength, good dimensional stability at low temperature, low thermo conductivity, etc.

Storage
Shelf life is six months minimum when stored at 59oF~68 oF and suitable storage environment. Like most construction materials, it must be stored in a dry, cool and well-ventilated place free from direct sunshine and other heat sources.
As it is easy to volatilize and absorb moisture, please use it up once. If not, please do keep the rest sealed right after use in order to prevent it from moisture and volatilization.

Safety & Precaution
*Please do wear rubber gloves, safty glasses and guarding clothes before application. Gloves should be changed frequently, working environment should be well-ventilated, equipments should be checked regularly and application site should be kept clean.
*polyether has slight toxicity because of the existence of low-density additives such as catalyst in it.
*The material is flammable.
*Once contacted with eyes: flush with low-pressure and clean water for at least 15 minutes and go for doctor at once.

Once contacted with skin: flush with clean water and wash with soap.
