AR 741

Technical Datasheet | Supplied by Aronkasei

AR 741 by Aronkasei is styrene-ethylene/butylene-styrene (SEBS) grade.

Exhibits excellent rubber elasticity & excellent cold resistance, excellent molten flow characteristics (moldability), excellent weather-, climate-, ozone-, heat resistance & resistivity against acids and alkali inorganic chemicals.
Offers anti-slippery products, reusable scrap such as runners and cross-linked rubber.
Possesses excellent molten flow characteristics and favorable processability allows it to be suitable for composite molding of thin products with hardened resins and for EPDM substitute.
It can be processed using injection molding and extrusion.
It is recommended for industrial applications, automotive (peripheral parts for a lamp, grommets, gaskets, trims, edges, covers for door switches), electrical (vibration-proof rubbers, water-proof packing, electrical tool grips, foot rubbers, insulation covers and printer rollers).
AR 741 is also used in blade and tool trips, golf club grips, bicycles grips, water supply & drainage packing, furniture and parts for building materials.
