Read the text below about plastic and complete the text using the active or passive form of the verbs and modal verbs in brackets. One gap can be filled with the active or passive of the verb.Plastics (will give) additional characteristics such as fire retardancy to allow them to be used in aircraft parts in the future. Injection-moulded parts (may include) glass or carbon fibres for strength. Plastics (can mould) with a foaming agent which (will reduce) the density and hence the weight of the final component and reduce the material required so reducing the cost. The list of plastics appears to be endless but they fall into two categories, thermoplastics and thermosets. Thermoplastics (can melt and recycle) into new parts. Thermoset plastics are stronger than thermoplastics but (cannot recycle) into new parts and have to be disposed of in other ways.

The apprearance and performance of most polymers can be improved by the use of thefollowing additives:i. Plasticisersii. Fillersiii. Stabilisersiv. Colourantsv. Antistatic agents

A good candidate for bioderived polymers to enter the market is developed to replace the today used PET. Which polymer is this (full name)? Using this polymer as example, explain which hurdles green plastics face in order to become commercially relevant.
