The international plastics industry has taken a step forward to develop eco-friendly polymers in a bid to ensure a ‘green’ future for next generations. Bioplastics is the term used for plastic materials produced from renewable biological sources such as vegetable oil, corn starch and cellulose, rather than traditional plastics which are derived from petroleum.
The term bioplastics should not be confused with biodegradable:
Bio-based plastics are plastics that are obtained from at least 20% renewable raw materials. Bio-degradable is used for specially modified petro-chemical-based plastics which appear to bio-degrade. The importance of bioplastics is increasing rapidly and these materials are becoming more widely used either as a direct replacement for traditional plastics or as blends with traditional plastics.
Many manufacturers in the plastics industry are pro-actively driving bioplastic research and development and consumers are becoming more willing to invest in these bio-based alternatives. With a proven track record of responsible environmental practices and leading edge polymer solutions, Dotmar EPP have introduced the new range of ECOGEHR Bioplastics that includes 9 different ‘green’ materials based on PLA, cellulose, wood fibres or castor oil. Dotmar EPP can assist with applications advice, product selection and custom delivery programmes for these ‘green’ polymers.
PLA based materials:
PLA (polylactic acid) is a renewable raw material. The materials are biologically degradable. Materials made from PLA display good thermal insulation properties and good resistance to polar solvents. PLA based materials consume 65% less fossil fuels when produced and 80% less green house emissions.
- ECOGEHR PLA-N - Good mechanical properties, high rigidity, physiologically harmless.
- ECOGEHR PLA-L - Contains amount of lignin, natural fatty acids and waxes. Good mechanical properties.
- High rigidity, good impact strength to -30ºC. Physiologically harmless.
- ECOGEHR PLA-V - high toughness, good thermal insulation, variable elasticity.
- ECOGEHR PLA-WFA - Composite of polylactic acid and wood fibres. High mechanical strength, due to the bond with the wood fibres to the polymer and the polymers to each other. Good thermal insulation.
Cellulose based materials:
ECOGEHR C-L - A mixture of cellulose, natural fibres, lignin and fatty acids. This material is made of 100% renewable raw materials and is biologically degradable.
- High general strength
- Good impact strength
- High stiffness and modulus of elasticity up to 4248MPa
- Machinable similar to wood
Polyamides made from renewable raw materials bases on castor oil.
- ECOGEHR PA 6.10 - Low density, good impact strength, low water absorption and dimensionally stable.
- ECOGEHR PA 11 – good thermal, physical, chemical and mechanical properties. Good cold impact strength up to -40 °C, very low water absorption.
WOOD-Plastic Composites ( WPC):
Composites manufactured using a combination of standard plastic and wood fibres. As a result of the bond of plastics to wood fibres, the materials display high mechanical strength. These materials are suitable for outdoor use and machining is similar to that of normal wood. Anti-bacterial grades available
- ECOGEHR WPC-30PP - 30% PP and 70% Wood Fibres
- ECOGEHR WPC-50PVC - 50% PVC and 50% Wood Fibres
