MATERIAL PROPERTIE S LESSON 3 GCSE Design Technology Plastics & Polymers Do Now activity – Answer this GCE Past Paper exam Question. Plug sockets are made out of urea formaldehyde which is a thermosetting plastic. 1)Explain in detail why Urea Formaldehyde is suitable for the plug socket. [4 MARKS]. 8 minutes to respond. Test your knowledge & common sense against a year 12 exam question.

MATERIAL PROPERTIE S LESSON 3 GCSE Design Technology Plastics & Polymers Plug sockets are made out of urea formaldehyde which is a thermosetting plastic. 1)Explain in detail why Urea Formaldehyde is suitable for the plug socket. [4 MARKS]. How did you do? § UF is a thermosetting polymer and will not heat up and melt if there is a short circuit or electrical fire. § UF is an electrical insulator so will be safe for use with electrical appliances. Mark your response against the exam answer.

Q knowledge worksheet Quick – Handstoup can youquestions. name a fossil fuel? Quick Task: Can you think of daily products you use which is made from plastic. Write a numbered list in your book. We will discuss these shortly.

MATERIAL PROPERTIE S LESSON 3 Producing polymers GCSE Design Technology Plastics & Polymers are produced through a lengthy process called refining § Unprocessed (crude) oil is first extracted from underground, either at sea using an oil rig, or on land § It is then transported to a plant for conversion https: //www. youtube. com/watch? v=GYRw. Wy. G 3 Qqw

MATERIAL PROPERTIE S LESSON 3 Refining crude oil Heavy, sticky black crude oil is virtually unusable in its unrefined state. § It has to be converted & refined into other more useable products such as fuels.

MATERIAL PROPERTIE S LESSON 3 Fractional distillation GCSE Design Technology Plastics & Polymers Fractional distillation occurs when crude oil is heated in the crude oil distillation unit. § Each product has different sized molecules with different boiling points Q - How can this process be used to separate petrol from diesel? https: //www. youtube. com/watch? v=PYMWUz 7 TC 3 A

MATERIAL PROPERTIE S GCSE Design Technology LESSON 3 Plastics & Polymers Fractional distillation process Put the stages into order. The different stages are: Crude oil is heated to 350°C Heavier molecules stay at the bottom and lighter molecules rise to the top The crude oil vaporises & rises up the tower Hot oil is pumped into the base of the distillation tower As the crude oil cools, the molecules condense The fractions (hydrocarb ons) are siphoned off for cracking

Fractional distillation process Put the stages into order. Cut out the stages and discuss with your partner what you feel the process is from START to FINISH. Crude oil is heated to 350°C Heavier molecules stay at the bottom and lighter molecules rise to the top The crude oil vaporises & rises up the tower Hot oil is pumped into the base of the distillation tower As the crude oil cools, the molecules condense The fractions (hydrocarbons) are siphoned off for cracking

MATERIAL PROPERTIE S LESSON 3 GCSE Design Technology Plastics & Polymers Fractional distillation process How did you do? Move the cards into the correct order. The correct process order: 1) Crude oil is heated to 350°C 2) Hot oil is pumped into the base of the distillation tower 3) The crude oil vaporises & rises up the tower 4) As the crude oil cools, the molecules condense Write the process in 5) Heavier molecules stay at the bottom & your book. lighter molecules rise to the top 6) The fractions (hydrocarbons) are siphoned off for cracking

MATERIAL PROPERTIE S Cracking LESSON 3 GCSE Design Technology Plastics & Polymers This is the process of converting the large hydrocarbon molecules found in the separated fuel types into smaller, more useful versions. § The large molecules do not flow very well and are not suitable to be converted into plastics § Heat and pressure are used to break them up https: //www. youtub e. com/watch? v=GYR w.
