Mitsui EPT

1 1 Mitsui EPTTMTMG rommets, Hoses2 Mitsui EPTTM (Ethylene-Propylene-Terpolymer) is an EPT(EPDM) brand that is produced by Mitsui Chemicals through its state of the art olefinicpolymerization technology. With Mitsui Chemicals' advanced technology, we constantly develop new grades which allow us meet customer EPTTMis a material which excels in processability, weather resistance, heat aging resistance, electrical insulation properties, cold resistance, and chemical resistance. These properties are ideal in applications such as (but not limited to) automotive weatherstrips and hoses, building materials, and electrical EPTTM specializes in specially designed polymers which competitors cannot match, allowing Mitsui Chemicals to develop not only high performance products but quality products which exceed customer EPTTMis backed by experts who provide excellent technical support to each and every customer and adjust to their every demand, whether it is a general grade selection for a certain application, formulation adjustments for improved properties, or cost reduction methods using Mitsui is Mitsui EPTTM?

Weather and Ozone Resistance PropertiesThe weather and ozone resistance of EPT is excellent and surpasses most rubbers due to its chemical main chain of EPT consists of a very stable saturated hydrocarbon preventing the main chain from degrading even after being exposed to sunlight and/or high concentrations of ozone for long periods of Polymer StructureDiene Rubber Polymer StructurePolymer Backbone.

Heat and Cold Resistance PropertiesThe heat and cold resistance limits for EPT are broader than any other type of rubber due to its chemical main chain of EPT consists of a very stable saturated hydrocarbon allowing it to have excellent heat aging can be used for longer periods of time and in higher temperatures compared CR (Chloroprene Rubber) and other diene rubbers such as SBR and Electrical Insulation PropertiesEPT has excellent characteristics as an insulation material.
