AGC CHEMICALS AMERICAS, INC.

Requirements for Fuel Lines

�  Mechanical properties (Burst pressure, cold impact resistance, tensile elongation, etc.)

�  Long term durability (Lifetime) •  15 years, 150,000 miles

�  Fuel and chemical resistance •  CE5, CE10, CM15, CE22, CM30, CE85, E100 •  Bio fuels (Bio alcohol, Bio diesel; RME, SME, etc.) •  Auto oxidized fuels (aggressive fuels with high peroxide number)

�  Low permeation •  Euro4, Euro5, Euro6 •  LEV II, PZEV, LEV III

�  Conductive (USA , Japan)

�  Processability, thermoforming (Straight, corrugate)

�  Cost reduction

Trend of MLT System

•  Wide variety of fuels are being used •  Lower emission requirements •  Cost efficiency •  Oligomer free and conductive material for inner layer •  Wide range of MLT systems for fuel lines:

•  PA11/PA12 and PBT, PBN, PVDF, ETFE, EFEP, EVOH, PPS MLT systems

•  Layer construction of MLT has grown more complicated

Advanced Multi-Layer Tube System

AGC, KURARAY and UBE jointly developed 3-layer tube system in order to offer: •  High level of low permeation system against variety of fuels •  Low oligomer wash out system •  Reasonable cost performance system Outer layer •  Modified-PA12 with excellent cold impact resistance and

long term heat resistance Middle layer •  Modified-PA9T with excellent hydro-carbon barrier properties and

good chemical and hydrolysis resistance Inner layer •  Modified-ETFE with excellent alcohol barrier properties •  Fuel, chemical and hydrolysis resistance (including aggressive oxidized fuels and

high alcohol-based fuel) •  Adhesive properties
