Mar 5, 2018 Abstract: This paper presents the interfacial optimisation of wood plastic composites (WPC) based on recycled wood flour and polyethylene by employing maleated and silane coupling agents. The effect of the incorporation of the coupling agents on the variation of chemical structure of the composites.
Whereas an increase in the E-modulus is desirable, a reduction in the impact strength is certainly not. Through the use of SCONA coupling agents, which significantly enhance the bonding of wood fibers with the polymer matrix, mechanical properties such as bending strength and impact strength of the composite material
Wood-plastic composites, or WPCs, are already a 1.3-billion-lb market and are growing at 20% annually. Lilli Manolis Coupling agents bond the wood fiber to the resin matrix. Equistar Chemical offers the Integrate series of maleated PE coupling agents for PE-based composites, plus new maleated PPs for wood-PP.

WPC are thermoplastically processible composites made from the renewable resource wood, mostly synthetic plastics and additives. A typical WPC product for example is an extruded profile for a veranda decking, consisting of 70% wood flour, 25% polyethylene or polypropylene and 5% additives such as bonding agents,
WPC consist predominantly of a lignocellulosic component in a proportion of up to 70 percent by mass, a thermoplastically-processable polymer of up to 50 percent by mass, a bonding agent and other additives such as pigments, light stabilizers or lubricants. For their manufacture, processing procedures for plastics are

To improve the adhesion properties, the surfaces of polyethylene wood plastic composites (WPCs) were treated by a combination of sanding then coating with a silane coupling agent, followed by plasma discharge. The surface properties of polyethylene WPCs were studied by assessing the contact angle and bonding

Abstract—In an effort to improve the adhesive bonding between wood–plastic composites (WPCs) formulated with polypropylene and a commercial epoxy adhesive, surface treatments were performed to chemically and/or physically modify the surface of WPCs. The treatments were performed on extruded WPC that had
This paper aimed to confirm which adhesive is more suitable to glue the PVC wood-plastic composite materials between epoxy adhesive and J-39 acrylic ester adhesive. This paper tested compression shear strength and aging properties of PVC wood-plastic composite materials glued with these two adhesives. The results
