Title:
High mechanical strength wood polymer composites by use of a new polyurethane binder system

Abstract:
A new type of binder for wood particles or fibres was developed using a
recycled polyol from polyurethane or PET wastes and a polyisocyanate
as raw materials. The binders developed with various ratios of hydroxyl
and isocyanate groups are solid at room temperature with melting points
between 40 and 60°C. Between 5 and 20% of these were mixed with the
wood products and compression-moulded at temperatures between 80
and 100°C and 0.75 to 2.05 kp/mm² pressure to give composites of
tensile strength up to 47 N/mm² or flexural strength up to 58 N/mm².
