Non stick frying pan presentation

  1. 1. PRESENT BY: LOH YU WEI 136256C WANG DONG 130529C CHENG YUN SHENG 136265M JOEL NG 131079Y LEONG JING YUEN TERRENCE 134192H
  2. 2. In this presentation we are going to let you know about : The material that used to produce a Non- stick frying pan. The properties of the materials. The reason of using those material. The environmental issue that the material bring to us.
  3. 3. Stainless Steel 304 Phenolic Resin Polytetrafluoroethylene(PTFE) or Teflon
  4. 4. Chemical Composition: Chromium - 18-20% Nickel - 8-10.50% Manganese - 2.00% max Carbon - 0.08% max Sulfur - 0.030% max Silicon - 1.00% max Phosphorus - 0.045% max Structure: Austenitic metallurgical structure.
  5. 5. Synthetic polymers obtained by the reaction of phenol or substituted phenol with formaldehyde. In the form of Bakelite, they are the earliest commercial synthetic resin.
  6. 6. Formed by a step-growth polymerization reaction that can be either acid- or base- catalysed. Found in myriad industrial products. First plastic made from synthetic components. Widely used for its heat-resistant properties in kitchenware.
  7. 7. PHYSICAL PROPERTIES MECHANICAL PROPERTIES TECHNOLOGICAL PROPERTIES CHEMICAL PROPERTIES ECONOMIC PROPERTIES AESTHETIC PROPERTIES
  8. 8. 1. STAINLESS STEEL 304: Stainless Steel 304 has high strength. Stainless steel 304 has good formability. Stainless steel 304 has high rigidity.
  9. 9. 2. PHENOOLIC RESINS: Phenolic Resins has high strength. Phenolic Resins has good formability. Phenolic Resins has low toughness. Phenolic Resins has high durability.
  10. 10. 3. Polytetrafluoroethylene (PTFE) Polytetrafluoroethylene (PTFE) has high strength. Polytetrafluoroethylene (PTFE) has low rigidity. Polytetrafluoroethylene (PTFE) has low toughness.
  11. 11. 1.STAINLESS STEEL 304: Stainless steel 304 has poor machinability. Stainless steel 304 has high castability. Stainless steel 304 has high
  12. 12. 2. PHENOLIC RESINS Phenolic Resins has high machinability. 3. POLYTETRAFLUOROETHYLE NE (PTFE) Polytetrafluoroethylene has high machinability. Polytetrafluoroethylene is easily formable.
  13. 13. 1. STAINLESS STEEL 304: Good oxidation resistance. Good corrosion resistance. Good chemical resistance.
  14. 14. 2. PHENOLIC RESINS High corrosion resistance. Good chemical resistance. 3. Polytetrafluoroethylene (PTFE) Chemical inert. Good corrosion resistance.
  15. 15. 1. STAINLESS STEEL 304: Cost of raw material and manufacturing is reasonable. Industrially widely available readily.
  16. 16. 2. PHENOLIC RESINS Cost of phenolic resins is dependent on the application. Material can get quite easily.
  17. 17. 3. POLYTETRAFLUOROETHYLENE (PTFE) Have a relatively low cost for its raw material and manufacturing cost. Can get it quite easily.
  18. 18. 1. STAINLESS STEEL 304: Has a beautiful appearance. Good texture for cook. Has an attractive appeal.
  19. 19. 2. PHENOLIC RESINS: Nice appearance. Good texture. Attractive look. 3. Polytetrafluoroethylene (PTFE): Suitable texture for cook.
  20. 20. 1) STAINLESS STEEL 304: Able to withstand cooking temperatures. Able to fry food quickly. Hygienic. Durable. Able to attract consumer’s attention. does not bend and break under normal use. Reasonable manufacturing cost.
  21. 21. 2) PHENOLIC RESINS: Wont break, deform or melt under high temperatures. Will not burn user’s hands. Durable. Will not slip out of user’s hands. Promote sales.
  22. 22. 3) Polytetrafluoroethyle ne (PTFE) Does not melt or burn during usage. Very unlikely for food to stick onto the coating. Durable. Hygienic. It would be easier for consumer to use.
  23. 23. A.Effect of using materials. B.Ways to solve the problem. C.Better material that can replace.
  24. 24. A. Effects of using materials Stainless Steel 100% Recyclable. Long term life. PTFE (Polytetrafluoroethylene) Non-biodegradable. Deadly to birds . Cause symptoms in humans. Phenol formaldehyde resin Non-biodegradable. Toxicological effect.
  25. 25. B.Ways to solve the problem Stainless Steel: ---- PTFE & Phenol formaldehyde resin Combustion into renewable energy Landfills.
  26. 26. C.Better Material That Can Replace Stainless Steel: Cast Iron Extremely Long Lasting Gives off Iron Particles Completing the Recycling Process PTFE Coating: Thermolon PTFE-free Use no PFOA in manufacturing Phenol formaldehyde resin: wood Bio-degradable Recyclable
