Spin Finish Oils

SDT-110 is a spin finish of synthetic fibers such as polyester and nylon. Its attributes/elongation are outstanding: the stability from heat is brilliant. Therefore, not much fume occurs, and the friction force is outstanding. SDT-110 has a soft feeling to the touch.

For semi-rigid foams

The product contains nitrogen, and it is a product to be used as a cross-linking agent in terms of hard or semi-hard foaming. This product is used to foam a product with excellent size stability and compression strength by blending and foaming the polyol with a small functional group, namely triol or tetraol.
System for Integral skinned foams

The product has a high reactivity, and various semi-hard foams including highly elastic semi-hard, impact absorbing semi-hard, high load semi-hard foams and semi-hard foams that are close to hard foams with a high reactivity, can be produced through reactions with a cross-linking agent and crude MDI. In mold forming, forming is carried out at a relatively low temperature without external heating, and so the product is suitable for an all-in-one mold forming of goods with the synthetic resin that is sensitive to heat, such as PVC, as the outer surface. When using the product as an impact absorber and as an energy absorbing foam, such as in car bumpers, the product can obtain an outstanding property of foam with good impact resistance.
For ordinary semi-rigid foams

Various semi-hard foams including highly elastic semi-hard, impact absorbing semi-hard, high load semi-hard foams and semi-hard foams that are close to hard foams with a big reactivity can be produced through reactions with a cross-linking agent and crude MDI. In mold forming, the forming is carried out at a relatively low temperature without external heating, and so the product is a suitable all-in-one mold forming of goods with synthetic resin as the outer surface, such as a PVC that is sensitive to heat. When using the product as an impact absorber and as an energy absorbing foam, such as car bumpers, the product can obtain an outstanding property of foam with good impact resistance.
High Ball Rebound System

High quality seat pads can be manufactured with outstanding repulsive force elasticity and durability.
For ordinary high resilience flexible mold foams

The product's reactivity is high, and even and open cell's soft mold foam can be obtained by mixing with TDI-80/C-MDI.
For flexible hot mold foam

The product's reactivity is very high, and is the most suitable for soft mold foam. In case of soft mold foaming, curing is quick, so the mold cycle is reduced, mold releasing is easy. Consequently even mold releasing film is formed.
For high hardness flexible slab-foam

The product, containing a high concentration copolymer, is the polyol for slab stock foam, and it is good in terms of common use with the polyol for general soft foam. So, the product has safe dispersion attributes, and its hardness can be adjusted randomly by setting the mixing ratio. As the catalyst scope of use is broad, reactivity control is easy to be suitable for the foaming process, flame retardancy is excellent, and so the amount of flame retardant used can be reduced. The excellent property of foam including tearing strength and elongation is outstanding.
For high resilience flexible slab-foam

Highly elastic soft slab foam with high reactivity can be manufactured. Highly elastic foam can obtain foam with excellent properties including tensile strength and tearing strength. Therefore, this product is developed for cushion material for furniture, beds, and also for toys. When spraying high resilience foam, the scorching of foam can be prevented, and elongation and compression strength are high.
