Products Phenolic moulding compounds

Phenolic moulding compounds

Phenolic molding compounds are thermosetting plastics. Thermosets offer many advantages over basic thermoplastics and are suitable for compression, transfer, or injection molding...They are produced in a precise and vibrant range of colors. This material has superior high voltage resistance, high mechanical strength, good heat resistance, good dimension stability, and superior chemical resistance.

All of these items may be variable according to customer pressing conditions.

Packing:   • 25Kgs. net laminated polyethylene bags.                                                               

Handling:   It is advisable to wear a dust mask while emptying the bags. Hands should be thoroughly washed at the end of the working day and before meals.  

Storage:   • Storage at 250c gives stability for several years.

                 • A higher temperature affects the materials flow and its mouldability

 

Major application areas

  • Many applications in electrical and electronic markets: insulation boards, switching parts, electrical devices, parts for telecommunication use, commutators, and wiring devices
  • Automotive parts .
  • Household appliances.
