    • PRESENT BY: LOH YU WEI 136256C WANG DONG 130529C CHENG YUN SHENG 136265M JOEL NG 131079Y LEONG JING YUEN TERRENCE 134192H
    • 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.
    • Stainless Steel 304 Phenolic Resin Polytetrafluoroethylene(PTFE) or Teflon
    • 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.
    • 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.
    • 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.
    • PHYSICAL PROPERTIES MECHANICAL PROPERTIES TECHNOLOGICAL PROPERTIES CHEMICAL PROPERTIES ECONOMIC PROPERTIES AESTHETIC PROPERTIES
    • 1. STAINLESS STEEL 304: Stainless Steel 304 has high strength. Stainless steel 304 has good formability. Stainless steel 304 has high rigidity.
    • 2. PHENOOLIC RESINS: Phenolic Resins has high strength. Phenolic Resins has good formability. Phenolic Resins has low toughness. Phenolic Resins has high durability.
    • 3. Polytetrafluoroethylene (PTFE) Polytetrafluoroethylene (PTFE) has high strength. Polytetrafluoroethylene (PTFE) has low rigidity. Polytetrafluoroethylene (PTFE) has low toughness.
    • 1.STAINLESS STEEL 304: Stainless steel 304 has poor machinability. Stainless steel 304 has high castability. Stainless steel 304 has high
    • 2. PHENOLIC RESINS Phenolic Resins has high machinability. 3. POLYTETRAFLUOROETHYLE NE (PTFE) Polytetrafluoroethylene has high machinability. Polytetrafluoroethylene is easily formable.
    • 1. STAINLESS STEEL 304: Good oxidation resistance. Good corrosion resistance. Good chemical resistance.
    • 2. PHENOLIC RESINS High corrosion resistance. Good chemical resistance. 3. Polytetrafluoroethylene (PTFE) Chemical inert. Good corrosion resistance.
    • 1. STAINLESS STEEL 304: Cost of raw material and manufacturing is reasonable. Industrially widely available readily.
    • 2. PHENOLIC RESINS Cost of phenolic resins is dependent on the application. Material can get quite easily.
    • 3. POLYTETRAFLUOROETHYLENE (PTFE) Have a relatively low cost for its raw material and manufacturing cost. Can get it quite easily.
    • 1. STAINLESS STEEL 304: Has a beautiful appearance. Good texture for cook. Has an attractive appeal.
    • 2. PHENOLIC RESINS: Nice appearance. Good texture. Attractive look. 3. Polytetrafluoroethylene (PTFE): Suitable texture for cook.
    • 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.
    • 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.
    • 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.
    • A.Effect of using materials. B.Ways to solve the problem. C.Better material that can replace.
    • 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.
    • B.Ways to solve the problem Stainless Steel: ---- PTFE & Phenol formaldehyde resin Combustion into renewable energy Landfills.
    • 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
