Slush molded TPE-S Instrument Panel
Inteva
• Uses PP/SEBS compound
• Currently commercial in North America
• Concerns over scratch/mar resistance?
Kraton/So.F.ter
• Uses special low molecular weight HSBC compounded with PP and Polybutene
• Currently under development/commercial applications yet to be announced
• New Formosa plant comes on stream in 2016 with capabilities to supply low molecular weight resin
PVC Substitution: Coated Fabrics
• TPE-S (SBC-TPEs:) Phthalate-free, UV resistance, low temp properties
Auto Acoustics Control Technologies: Role For TPEs
(a) High growth application for SBC and o-TPVs
(b) Lightweight dash mats and heavy duty barriers (e.g. from Cascade Engineering).
includes polyolefin foams
(c) For example Betafoam™ from Dow based on PU foams
(d) For example from IAC/Stankiewicz
(e) Becoming common via feedback microphones (e.g. Honda Accord and Chevrolet Impala)
(f) BSR= Buzz, squeak, rattle: opens opportunity for vibration damping TPE layer on plastic substrates
