Description

Molecular weight 5000 POLYETHER POLYOL for High Resilience Polyurethane Foam has higher reactivity, and has the product characteristics of not being able to smell with nose. In the early and middle stages of foaming, the foaming rate is moderate, and a fast gel rate in the later stages, which can meet the foaming needs of different densities and high resilience sponges in most environments.

 

Standards and performance‌

 

The standards for high-resilience sponge made of highly active polyether polyols include indicators such as density, tensile strength, rebound rate, compression deformation and durability. These standards ensure the quality and performance of the product and provide better support and comfort. For example, the density is generally between 30-80kg/m³, and the rebound rate is usually between 50%-90%. These indicators together guarantee the excellent performance of high-rebound sponge.

 

Application

 

Molecular weight 5000 POLYETHER POLYOL for High Resilience Polyurethane Foam is widely used in many fields due to its unique physical and chemical properties, including but not limited to soft beds and mattresses, car seats, motorcycle cushions, sofa cushions, sports protective gear, etc. This sponge material has been widely welcomed and applied due to its high elasticity, high resilience, health and environmental protection.

In addition to its application in the home field, high-resilience sponge is also widely used in the automotive industry, toy industry, sporting goods industry, etc. For example, in the automotive industry, high-resilience sponge is used to make car seats, backrests, etc., providing comfort and support. Its good shock resistance, softness, good tear strength, easy hardness adjustment, good resilience, good elasticity, etc. make high-resilience sponge an ideal choice for a variety of products‌.

HANDLING PRECAUTIONS

 

Flash point is above 200℃ (open cup method), flammable but non-explosive. In case of fire, put out with

foams, dry powder, steam or water.

When handling polyols, precautions should be taken to avoid exposure to the eye or prolong contact with

the skin. If eye contact occurs, flush with plenty of water. If skin contact occurs, wash exposed areas

thoroughly with soap and water.

 

Packing

 

200KGS/drums, IBC tank

It is slightly hygroscopic and may absorb water. Containers should be kept sealed and protected from contamination of moisture and foreign materials.

The shelf life is 12 months. After that, the pre-test should be made before use.
