Microsoft Word - 55453- PolyOne Corporation RCMS 2013 Option 2.docx ABS Quality Evaluations Letter Of Conformity Page 1 of 1 This is to confirm that the Environment, Health, Safety and Security Management System of: PolyOne Corporation 33587 Walker Road Avon Lake, OH 44012 U.S.A. has been assessed by ABS Quality Evaluations, Inc. and found to be in conformance with the requirements set forth by: RCMS®:2013 (Option 2) The Environment, Health, Safety and Security Management System is applicable to: Responsible Care Management System activities and corporate supported processes associated with the design and manufacture of plastic compounds, colorants, thermoplastic elastomer compounds, color concentrates and compounding of thermoplastic products.

The substrates materials employed for overmolding were PP, ABS, PC/ABS, polyester, Nylon and POM. These TPEs have exhibited good adhesion on various substrates including PP, PS, HIPS, PMMA, PC, PET, ABS, PC/ABS and Copolyester. TPE-1A adhesion values overmolded onto PP, PC and ABS over a wide range of melt temperatures.
