Fibres

Fibres • Network of interwoven fibres / matting (1) gives increased strength / toughness / flexibility (1) resulting in the polymer being able to resist greater forces / shock loads/ improve strength to weight ratio. (1)

1 of 5

Stabilisers

Stabilisers • Increased resistance to UV light / sunlight (1) does not fade / yellow or become brittle / increased life of product. (1) • Increased resistance to heat (1) so does not degrade under injection molding. Is a bio stabiliser.

2 of 5

Foamants

Foamants • Cause polymer to form into a cellular structure / fill with bubbles / increasing its volume (1) improving the polymers volume to weight ratio / buoyancy / elasticity / flexibility / toughness / insulation properties. (1)

two advantages to the environment of using Biopol® in products.

Biodegradable / rots quickly (1) so takes up less space in landfill / reduces long term unsightly litter / releases nutrients (1) • Will not consume finite sources of oil (1) extending supply (1) • Sustainable polymer (1) as it can be re-grown.

4 of 5

how micro-organisms are used to aid the disposal of environmentally friendly polymers.

Biopol exposed to micro-organisms in soil / water / sewage. (1) • Micro-organisms break down / degrade the polymer. (1) • The more micro-organisms the faster the degradation. (1) • Industrial / commercial composting systems can be used. (1) • Redu
