Thermoplastic Elastomers (TPE/TPR)

Both TPE and TPR belong to the family of Thermoplastic Elastomers. TPE is modified from SEBS base material while TPR is often modified from SBS.

ABOUT TPE/TPR

Styrene-Ethylene-Butylene-Styrene Block Copolymer (SEBS) is the product of hydrogenated SBS. It’s styrene-butadiene-styrene block copolymer, which offers soft-touch characteristics utilized extensively by designers – especially in hand tools.

What does this mean in relation to SEBS? It’s the act of introducing molecular hydrogen to unsaturated molecules in special reaction conditions. This ensures that the molecular structure becomes saturated, which offers anti-aging properties, as well as resistance to yellowing. In addition, it also ensures higher heat and corrosion resistance than SBS, therefore resulting in a higher performance output of TPE over TPR.

TPE (modified from SEBS base materials) typically exhibits a matte surface with light astigmatism.  It is flexible and smooth.  Common uses are food products, medical, healthcare, sealing rings, caps and closure liners.

TPR (modified from SBS base materials) has a glossy and reflective surface.  Typically used with products that need to be glued with adhesives or which require glossy surfaces.
