Metal; Ferrous Metal; Austenitic; Cast Iron. Material Notes: Type CRS is an austenitic material with graphite in the nodular form. It conforms to ASTM designation A439-60T and provides much higher strength than type CR with excellent resistance to corrosion, wear and heat.
TPR: Thermoplastic Rubber. S&E Specialty Polymers is a leading manufacturer of Thermoplastic Rubber (TPR) Compounds that are available for a wide-range of applications.These compounds are formulated using Styrene-Butadiene-Styrene (SBS) or Styrene-Ethylene/Butylene-Styrene (SEBS) block co-polymers.These materials have many of the same properties as vulcanized rubbers, but can be molded and extruded using conventional thermoplastic process equipment.hese compounds can be formulated to provide weather resistance, ozone resistance, low temperature flexibility as well as excellent resistance to many chemicals. They are light weight and can be colored to meet your requirements.
