Styrenic Thermoplastic Elastomers (TPE-S)

Features & Benefits

Materials Features

Good Responsiveness,

High Elasticity,

Light Weight,

Low Compression Set

Features

・Energy-Returning Responsiveness : The rubber-like material is bouncier than EPS and traditional soft foams, offering responsive energy return.
・Flexible : The material has a similar flexibility to traditional soft foams, despite being expanded polystyrene.
・Shape Restorability : With the compression permanent set of 5% or less, the material exhibit good shape restorability, making it less susceptible to deformity.
・Can be molded into any shape : Pre-expanded resin beads are filled into molds to produce foams of the most complex shapes.

Applications

Taking advantage of ELASTIL’s properties such as lightweight, flexibility, high bounce and elasticity, it can be used the following fields and applications:

Properties

Elastil Has Excellent Properties

Lightweight
Density of ELASTIL is 0.10~0.15 [g/cm³] which is very lightweight.

Bounce property / Elasticity
ELASTIL has extremely outstanding properties of bounce and elasticity compared with the other foams, PU foam/PVC foam (open cells), and EPP (closed cells). Such properties like a spring and lightweight property can be used for a wide range of applications.

Flexibility / Softness
ELASTIL is very flexible and soft, and has high resilience property which conventional bead foams could not achieve. The compression set of ELASTIL flexible grade is about 3-6 %, thus the strain after compression does not remain easily compared with EPS and EPP.

Shapability / Mass Productivity
ELASTIL is molded with steam heat after filling small particles (pre-expanded beads) into a mold/tooling. Different from foam boards, it has high degree of design freedom and does not need secondary work, such as cutting, sealing and trimming, even in 3D shapes.

Non-absorbent / Thermal Insulation
ELASTIL foams have the closed cell structure therefore it has less absorption and better thermal insulation than open-celled soft foams.
