RTP Company, a custom-engineered thermoplastic compounder, has introduced a line of engineered bioplastic speciality compounds, utilising resins derived from rapidly renewable resources.

Initial bioplastic compounds based on polyamide, polyester and polylactic acid (PLA) are available in grades providing conductive, flame-retardant, structural and wear-resistant value-added properties.

The company’s bioplastic compounds contain 20 per cent to 80 per cent bio-content by weight and were developed to meet the need for alternative ‘green’ materials.

Andy Lamberson, corporate development manager at RTP Company, said: ‘Bioplastic compounds, utilising components derived from rapidly renewable resources instead of petroleum, are the latest element of an RTP Company initiative to develop “greener” products to meet diverse industry requirements.

‘The use of bioplastic compounds lessens dependence on non-renewable resources.

‘They also have a lower carbon footprint – their manufacture emits less CO2 and requires less energy, making them more environmentally favourable than traditional plastics,’ he added.

Initial development has resulted in more than a dozen bioplastic compounds that meet a variety of application requirements.

Research into additional formulations continues, along with the development of custom materials to meet specific end-use requirements.

Prospective applications for bioplastic compounds include automotive interior and industrial components, semi-durable consumer goods and housings and enclosures for electronics or business equipment.

Bioplastic polyamide and polyester-based compounds are halogen-free flame retardant and are available with glass-fibre reinforcement, antistatic protection and PTFE lubrication.

PLA grades are combined with PC, PMMA or ABS in hybrid formulations that increase mechanical performance and offer antistatic, flame-retardant and structural properties.

A 32 per cent bio-content PLA/PC alloy has a notched IZOD impact strength of 15ft-lb/in (800J/m) and a 40 per cent bio-content PLA/PMMA alloy is optically clear.

All current bioplastic grades are fully colourable to standard and custom-matched colours.

Lamberson continued: ‘Bioplastic compounds join RTP Company’s other materials, such as halogen-free flame-retardant and recycled post-consumer content grades, which help processors and OEMs [original equipment manufacturers] meet their goals and consumer demands for manufacturing more environmentally conscious products.’
