RTP Company (RTP) has commercialised its glass fibre-reinforced polylactic acid (PLA) compounds aimed at delivering greater strength, stiffness, and thermal performance.
According to RTP, their latest extension of engineered bioplastic compounds use resins derived from rapidly renewable resources target durable and semi-durable applications and are targeted at durable and semi-durable applications. ""Our new glass fibre reinforced PLA compounds enhance the strength and temperature performance of PLA making it possible for PLA to be considered for much broader use,"" said Will Taber, Business Manager for Emerging Technologies at RTP.
RTP explain that their reinforced PLA grades have glass fibre loadings from 10% to 40%, and have the ability to customise glass level to meet application requirements in appliance, automotive, consumer goods, electrical & electronics, and construction markets. They report that the 30% glass fibre-reinforced PLA grade has a tensile strength of 16,500psi (114 MPa), flexural modulus of 1,630,000 psi (11,239 MPa), and heat deflection temperature (HDT) of 320°F at 66 psi (160°C at 455 kPa), which they claim is nearly twice the tensile strength of unmodified PLA. ""RTP Company can now produce PLA bioplastic compounds with mechanical properties that meet or exceed those of many traditional thermoplastics,"" said Taber.
Proprietary nucleation packages are designed to speed crystallisation, which increases temperature performance and allows quicker part ejection, yielding PLA injection moulding cycle times similar to PP and ABS. Several nucleating package option are available to balance cost and performance requirements. ""We have really just begun to scratch the surface of what can be done with compounding PLA,"" said Taber.
At SAMPE 2018 in Long Beach, Technical Fibre Products (TFP) will exhibit its advanced nonwovens, including the Tecnofire fire protection range, nano-coated materials and coated materials and Optiveil lightweight veils which aid surface finish and composite fabrication.
On 5 June 2018 at 11:00 am EST (5:00 pm CEST), Matthias Lange, Product Manager at LAP, will deliver a free webinar on the topic of Camera-Assisted Laser Projection for Acceleration of Manual Composite Lay-Up, which will give practical and technical insights into camera-assisted laser projection.
The American Composites Manufacturers Association (ACMA) and NetComposites have announced the detailed conference programme for the Global Composites conference. This new international composites industry event is designed for corporate and division leaders in the industry with a focus on global business, trends and insights for the global composites market.
