Pineapple Leaf Fibre Reinforced Biocomposite Compound (PLA/PBAT)

About This Product

This grade is a compound of polylactic acid and polybutylene adipate terephthalate reinforced with pineapple leaf fibre, supplied as a pellet compound for injection moulding and extrusion. PLA supplies stiffness and PBAT the toughness PLA lacks, while the reinforcement is a cellulosic natural fibre dispersed through the melt during compounding. The compound is biodegradable at end of life. Pineapple leaf is a residue of fruit harvesting, normally burned or left to rot. Used as reinforcement it raises the stiffness and strength of the polymer while displacing part of the resin with a material that would otherwise be waste. The mechanism is load transfer across the fibre-matrix interface: cellulose fibres are far stiffer than the polyester around them, so modulus rises with fibre content and aspect ratio. The result is a biocomposite with both a higher renewable content and better mechanical performance than the unfilled compound. Cellulose is polar and hygroscopic while the matrix is not, so natural fibre affects flow and moisture uptake, and drying and processing conditions differ from the unfilled grades and should be reviewed before a first trial: water carried in on the fibre will hydrolyse PLA in the melt. Supplied as a raw material for processing on the buyer's own line; we do not produce finished articles. It is used in structural biocomposite parts, consumer durables and agricultural residue valorisation. Bio Green Chem supplies the pineapple leaf fibre reinforced PLA/PBAT biocomposite to specification on polymer ratio, fibre content, moisture content and pellet form.
