Material Technology

COI Chemist Engineer Specific material compounds for individual needs.  We understand that our customers need to know the parts we supply will perform as required in service, each and every time. That’s why we pay close attention to application variables and help our customers choose the best rubber and plastic materials — based on physical, chemical and thermal requirements — for each situation. We can also formulate and test custom compounds in our material development laboratories or any other A2LA certified laboratories.

RUBBER TECHNOLOGY IS CONDUCTED WITH A TRANSFORMATION OF ELEASTOMERS INTO USEFUL PRODUCTS
  • Vulcanization
  • Processing of Rubber
  • Glass Transition Temperature
  • Stress Relaxation / Creep
  • Mastication, and various process operations.
  • Breaking down molecular mass so that the viscosity is low enough for further processing
  • Syntheic Rubber & Petrolium
  • Natural Rubber & Poly-CIS-isoprenes
  • Thermal Elastomers (TPE)
  • Styrenic block copolymers (TPE-s)
  • Polyolefin blends (TPE-o)
  • Elastomeric Alloys (TPE-v or TPV)
  • Thermal Polyurathanes (TPU)
  • Thermoplastic copolyester
  • Thermoplastic polyamides
  • Mixing, Calendering, Extrusions, Pre-forming, and Extrusions both co-extruded with wire and clip
