SRS-32P and SRS-40P foams are both from Japan's Inoue Company and are two high-performance polyurethane foam materials. With their unique structures and properties, they are widely used in electronics, automobiles, construction, furniture and other fields, providing products with filling, sealing, sound insulation, cushioning and other solutions.

SRS-32P

SRS-32P foam is a low-rebound foam material synthesized with PET film. It is both soft and rigid, and can quickly return to its original form after being subjected to external forces, effectively absorbing and dispersing impact forces. In addition, SRS-32P foam also has good weather resistance, chemical corrosion resistance and high temperature resistance, allowing it to maintain stable performance in a variety of environments. It is widely used in liquid crystal packaging materials for smartphones, computers, etc.

 

SRS-40P

SRS-40P foam is a high-performance foam material that is both soft and rigid. It is integrated with PET film and has low rebound. The density of SRS-40P foam is as high as 400kg/m³, which makes it have excellent performance when subjected to pressure and impact. At the same time, it also has excellent resistance to compression deformation, and is not easy to deform after long-term use, ensuring a long service life.

 

The difference between SRS-32P and SRS-40P foam

The most significant difference between the two is density and hardness. The density of SRS-32P foam is 320kg/m³, the 25% compression load is 0.010Mpa, and the 50% compression residual deformation is 2.2%. It is suitable for occasions that require a certain degree of softness and elasticity; while the density of SRS-40P foam is 400kg/m³, the 25% compression load is 0.018Mpa, and the 50% compression residual deformation is 2.0%. It is suitable for occasions that require higher strength and durability.
