Features
The standard type with all the Softlon's basic functions.
Eco-friendlyAmong resins for foam products, polyolefin is known to be environmentally friendly. |
Chemical resistanceIt isunsusceptible to chemi cals such as acid, alkali and organic solvents. thanks to its resistance to them. |
Thermal plasticity
It has the features of being stable form at normal room temperature and getting soft so as to be easily molded. when heated. |
Workability
It responds to various processing methods such as slicing, vacuum forming, embossing, lamination and printing. |
Electrical properties
It has high dielectric strength,insulation to high frequencies. and excellent in electrical properties |
 |
 |
 |
 |
 |
Water resistanceEven if it is left soaked in water for a long time, it absorbs little water. |
ToughnessIt has high mechanical strength, including tensile, tear and compressive strength. |
Smoothness With its uniformly sized and fine cells, it feels very smooth. |
Insulation
It achieves great insulation because it does not allow the air to convect in each cell, |
Buoyancy
Fine cells are uniformly arranged in this product, which prevents water from penetrating and makes it float in water or other fluid. |
 |
 |
 |
 |
 |
Light weightIt achieves light weight while keeping high mechanical strength for a foam product. |
Sealing performanceSoftlon achieves excellent flexibility and high adhesion, absorbs little water and demonstrates excellent waterproof performance. |
Flexibility(Shock-absorbing properties)
It has both elasticity, one of the characteristics of a cell structure, and flexibility , one of the characteristics of polyolefin. |
 |

Specifications
Softlon S has intermediate nature between the nature of soft urethane foam and that of polystryrene foam.Its shape can be flexibly changed. In addition, it has good tensile strength and flexibility, and achieves high elasticity, which relieves the feeling of pushing the bottom.

■Comparison of insulation of Softlon S and other materials
Softlon is made of polyolefin, which achieves low thermal conductivity and high insulation.In addition, since it has a closed-cell structure, it absorbs little water and its insulation performance is hardly degraded by moisture. It is also used in a wide variety of fields as an energysaving material with a function of keeping something warm and cool.

Properties of the higher-grade Softlon.
Heat insulation
| Softlon is a combustible foam material with a basic function of being resistant to 70℃ heat. However, both Softlon NF and Softlon SP have higher heat insulation, which are suitable to make a wide range of molding products. |  |

Flame retardancy
All the Softlon series are designed to burn at a slow pace and give off little black smoke and toxic gases.Softlon FR-ND and THERMOBREAK®-RT achieve higher fire retardancy so that they are suitable for use in producing special things such as railroad cars. |
Softlon FR-ND This meets flame retardant standards for the Japanese market ● UL standard UL94 HBF HF-1 (Home appliances / IT devices) ● A combustion test of materials for railroad cars |

Thermoformability
| Softlon is made of physically cross-linked polyolefin so that it is excellent in tensile strength, elongation and tear strength. Softlon SP and Softlon IF can be thermoformed so easily that they can be molded more flexibly, such as being deep drawn by vacuum forming. |  Press molding |
