1 Dream Weavers Vectra LCP For The Fusion Of Performance Polymers And Textile Expertise Technical Fibers

2 Vectra LCP engineering polymer is used by the industrial textile and fabric industry for fibers that stand up to temperature exposure, chemical and wear resistance, abrasion resistance and low moisture absorption. Vectra LCP is easy to process without sacrificing heat resistance and mechanical strength. Multi-filaments, fibers and non-wovens made from Vectra LCP can be used in a wide variety of applications and markets, including aerospace, military,* sporting goods, protective apparel, rope and cables, personnel life protection, medical, paper and non-wovens and other industrial segments. * Region specific High-Performance e ce Polymers (HPP) (TI 1 > 150 C) PI PEEK FP Price/Performance Engineering Polymers (ETP) (TI 1 > 90 C) COC PES PAR PC PPOO PEI PSU LCP PPSP PCT PA46 PET PBT POM LFRT CFR-TP PAI PPA PA 6/66 TPC-ET UHMW-PE Amorphous Partially Crystalline lin e TI 1 = Temperature Index 2

4 Fiber Structure LCP polymer molecules are stiff, rod-like structures organized in ordered domains in the solid and melt states. These oriented domains lead to anisotropic behavior in the melt state, thus the term liquid crystal polymer. This highly oriented fiber structure results in very high tensile properties. Fibers are formed from Vectra LCP by melt spinning through fine diameter capillaries, during which the molecular domains orient parallel to the long axis of the fiber. Vectra LCP Properties The exceptional property profile of Vectra LCP allows it to meet very demanding service requirements. Vectra LCP withstands temperatures below -160 C and as high as 250 C, with very good chemical resistance.

7 Chemical Resistance The results of testing in various chemicals, solvents and fuels are given below. Injection molded test specimens were immersed in the medium for a designated period of time with no stress applied. The application of mechanical stresses could alter the results. These data are for initial guidance only. Before commercial use the material should be tested using the identical processing and exposure conditions expected in actual use. Changes in concentration, temperature of exposure or the addition of additives can significantly alter the results. Five bars, 127mm x 12.7mm x 3.2mm, were immersed in the medium without external stresses. Changes in weight, and dimensions, flexural strength, flexural modulus and hardness were measured. Rating: + Resistant less than 2% change in weight and dimension, less than 5% change in mechanical properties. o Limited resistance Not resistant Medium Vectra A950 Rating Conditions (time/temperature) Acetic acid (100%) 30 days/118 o C + Acetone 180 days/56 o C + Brake fluid (Castrol TLX 988C 30 days/121 o C + Caustic soda solution 180 days/23 o C + (5%) 30 days/70 o C days/70 o C o Caustic soda solution 180 days/23 C + (10%) 30 days/88 C o Caustic soda solution (30%) 30 days/88 C Chlorine gas 180 days/23 C + Chlorine/water (saturated solution) 180 days/23 o C + Chromic acid (50%) 180 days/50 o C + 30 days/70 o C + 60 days/70 o C + Chromic acid (70%) 30 days/88 o C + Dimethyl formamide 180 days/66 C + Diphenylamine 180 days/66 C + Diphenyl carbonate 10 days/250 C Engine oil, 10W days/121 C + Ethanol 30 days/52 C + Ethyl acetate 180 days/77 C + NOTE: Data obtained from testing of molded bars Medium Vectra A950 Rating Conditions (time/temperature) Ethylene diamine 30 days/100 o C 180 days/23 C + Ethylene glycol (50/50) 30 days/50 C + 30 days/121 C o Fluorinert FC-70 1 day/215 o C + Formic acid (80%) 30 days/104 o C days/104 C o 455 days/104 C Fuels: Fuel C (ASTM D471) 50/50 iso-octane/toluene 30 days/121 C + 30 days/121 C + 30 days/121 C o Lead free gasoline (petrol) Lead free gasoline (petrol) + 10% methanol Gasoline (petrol) 30 days/121 C + with 70/30 heptane/ toluene, copper ion, t-butyl-hydroperoxide Hexafluoro-isopropanol 10 days/25 o C Hydrochloric acid (37%) 30 days/88 C days/88 C o Hydrofluoric acid (anhydrous) 30 days/23 C Hydrogen chloride (anhydrous) 30 days/23 C Methanol 30 days/64 C + Medium Vectra A950 Rating Conditions (time/temperature) Methylene chloride 180 days/40 C + Monochloroacetic acid 180 days/50 C + Nitric acid (50%) 60 days/70 C days/70 C + Nitric acid (70%) 30 days/88 C o Nitrobenzene 30 days/66 C + Nitroglycerine 30 days/66 C + Oil silicone 30 days/200 C + Oil hydraulic (Skydrol ) 30 days/71 C + Pentafluorophenol 10 days/60 C Phenol 100 days/100 C + Refrigerant R days/80 C + Refrigerant days/47 C + Sulphuric acid (50%) 180 days/88 C + Sulphuric acid (70%) 5 days/190 C Sulphuric acid (93%) 8 days/23 C o 30 days/121 C Toluene 180 days/111 C + Trichlorethane 90 days/66 C + Urea (46%) 60 days/88 C o Water 10 days/121 C + 40 days/121 C o 60 days/121 C o Water vapor 70 days/121 C o Vectra LCP Comparison to Other Fibers LCP* PPS M-Aramid PI PTFE PET PA 6 Continuous Temperature ( C) Density (g/cm 3 ) Melting Point ( C) Does not melt 1 Does not melt Moisture Absorption (%) LCI Value > Oxidation Resistance Wet Heat/Hydrolysis Resistance Resistance Against Acids Resistance Against Alkalis = Excellent + = Good 0 = Poor = Poor/Not Recommended *Vectra A series 1 35% tensile loss after ~200 hours at 304 C 2 ~ 250 C loses ~ half its strength in 400 hours Solid to nematic liquid transition point 7
