What is SeRM Super Polymer?

SeRM Super Polymer is a type of Polyrotaxanes. It is a raw polymeric material with improved solubility in solvents, compatibility with other materials for use in various industrial applications.

SeRM Super Polymer SH Series ( Polyol )

Products Outline

SeRM Super Polymer SH Series are polyrotaxane derivatives having hydroxyl functional groups, which are usable as a polyol materials in the application of coating, adhesive, sealant and elastomer. Expected benefits: scratch resistance, stress relaxation, flexibility, et al. Three grades are available. They are different in the length of polyethylene glycol chain.

SeRM Super Polymer SM/SA Series(UV or thermal radical curable type)

Products Outline

SeRM Super Polymer SM and SA series are polyrotaxane derivatives having radical crosslinkable functional groups. Similar to metacrylates or acrylates, it can be cured with UV light or heat under addition of radical initiators. These products are diluted in methyl ethyl ketone at concentration of 50 wt%. Expected benefits: scratch resistance, flexibility, strength improvement, reduction of shrinkage, et al.

【Example】
  Base material : Several kinds of non-woven fabric made from PET (10~25mm thick, 200~700g/m2 weight per unit area)
  Coating method : Surface coating using paint roller
  Curing method : Heated and dried at 100degrees for 30 minutes

 

SeRM Urethane Foam

Products Outline

SeRM Urethane Foam is a new soft urethane foam containing SeRM Super Polymer. Settling, one of the weaknesses of urethane foam, is drastically improved. Even under severe usage environment, SeRM Urethane Foam shows excellent compression set, and high body pressure dispersion.

 

Products Outline

 

Excellent Resilience

After performing cyclic compression at constant load (750N, 80,000 cycles), thedecrease of hardness (%) of the foam at 40% compression is measured.

Excellent Resilience

 

Excellent Body Pressure Dispersion

Seat/body pressure dispersions are compared using a sheet type pressure distribution measurement instrument.

Excellent Body Pressure Dispersion

SeRM Elastomer SH Series(Solvent-free one-component thermosetting resins)

Products Outline

SeRM Elastomer SH3400M is a solvent-free one-component thermosetting resin containing SeRM Super Polymer SH3400P.
Just by heating the elastomer liquids at 150℃ to 170℃ for about 2 to 5 hours, you can cure to form elastomer.

Products Outline

 

Features
1.Very soft material, rubber hardness 30

– Can be used in a wider temperature range (from -20℃(-4F) to 120℃(248F)) than urethane gel.

2.Very small deterioration

– Compression set for SH3400M is below 1%
– Low stress relaxation. Tensile strengh changes little under long sustained transformation.

3.Excellent vibration absorbency for wide frequencies

- Absorb both vibration and noise

4.Excellent optical transparency

-About the same transmittancy as an acrylic resin at visual light range.

5.Physical properties with fillers

– Smaller changes in properties than other existing polymers with fillers.
