Abstract

Abstract Methods for processing curable thermoplastic elastomers and particularly to flexible, shaped articles made therefrom which have improved high strength, radiation and temperature resistance and electrical characteristics useful as fluid transmission tubing and/or as electrical insulation. Such articles are made from uncured, thermoplastic elastomer materials - in the form of selectively hard, radiation, sensitive, flowable solids - which are thermoplastically molded to provide an essentially uncured, dimensionally stable, intermediate shaped article. Such intermediate articles are radiation-cured to provide finished cross-linked articles having such characteristics.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 109 words
AN ELECTRICALLY INSUALTED CONDUCTOR COMPRISING AN ELECTRICAL CONDUCTOR AND A LAYER OF HEAT RESISTANT, RADIATION RESISTANT, SUBSTANTIALLY DIMENSIONALLY STABLE ELECTRICAL INSULATION HAVING A HARDNESS OF AT LEAST ABOUT SHORE A 50 AND A TENSILE STRENGTH AT 100% ELONGATION OF AT LEAST ABOUT 400 P.S.I. ABOUT SAID ELECTRICAL CONDUCTOR, SAID INSULATION BEING THE NON-THERMOPLASTIC PRODUCT OF THE ELECTRON CURING WITH A DOSAGE OF AT LEAST ABOUT 1 MEGARAD OF A THERMOPLASTIC ELASTOMER REINFORCED AND HARDENED WITH FROM ABOUT 50 TO ABOUT 250 PARTS OF A FILLER PER 100 PARTS OF A THERMOPLASTIC ELASTOMER, SAID INSULATION CONTAINING SUBSTANTIALLY THE SAME AMOUNT OF FILLER AS THE THERMOPLASTIC COMPOSITION SUBJECTED TO ELECTRON CURING.
Claim 2
Dependent Claim 109 words
AN ELECTRICALLY INSUALTED CONDUCTOR COMPRISING AN ELECTRICAL CONDUCTOR AND A LAYER OF HEAT RESISTANT, RADIATION RESISTANT, SUBSTANTIALLY DIMENSIONALLY STABLE ELECTRICAL INSULATION HAVING A HARDNESS OF AT LEAST ABOUT SHORE A 50 AND A TENSILE STRENGTH AT 100% ELONGATION OF AT LEAST ABOUT 400 P.S.I. ABOUT SAID ELECTRICAL CONDUCTOR, SAID INSULATION BEING THE NON-THERMOPLASTIC PRODUCT OF THE ELECTRON CURING WITH A DOSAGE OF AT LEAST ABOUT 1 MEGARAD OF A THERMOPLASTIC ELASTOMER REINFORCED AND HARDENED WITH FROM ABOUT 50 TO ABOUT 250 PARTS OF A FILLER PER 100 PARTS OF A THERMOPLASTIC ELASTOMER, SAID INSULATION CONTAINING SUBSTANTIALLY THE SAME AMOUNT OF FILLER AS THE THERMOPLASTIC COMPOSITION SUBJECTED TO ELECTRON CURING.
