Polymer Materials and Their Applications

Front

Evaluate the impact of Kevlar fibres on sporting products.

Back

Kevlar fibres are used in bicycle tyres to prevent punctures, in personal protection equipment for abrasion resistance, and in high-end trainers for reduced elasticity.

Front

Describe the purpose of fillers in polymers.

Back

Fillers add bulk to products, reduce costs, and improve performance characteristics.

Front

Describe the purpose of plasticisers in polymers.

Back

Plasticisers improve plasticity, making polymers less brittle and reducing viscosity for better flow during manufacturing.

Front

Explain why High Density Polyethylene (HDPE) is suitable for outdoor chairs.

Back

HDPE is resistant to moisture, UV light, and does not degrade easily, making it ideal for outdoor use.

Front

What steps can manufacturers take to prevent polymer degradation in outdoor chairs?

Back

Manufacturers can add UV stabilisers and use moisture-resistant materials.

Front

What is rotational moulding?

Back

Rotational moulding is a manufacturing process where a heated hollow mould is filled with a polymer and rotated to create a uniform product.

Front

Name a product made from Urea Formaldehyde and explain its suitability.

Back

Urea Formaldehyde is used in adhesives and laminates due to its strength and durability.

Front

Name a fibre reinforced composite material.

Back

Fibreglass.

Front

For fibreglass, name a product and reasons for its suitability.

Back

Product: Boat hulls. Reasons: Lightweight and strong, resistant to corrosion.

Front

Explain why Thermoplastic Elastomer (TPE) is suitable for TV remote controls.

Back

TPE is flexible, durable, and provides a comfortable grip.
