Coupling agents enhance performance of wood plastic composites Styrenic polymers such as PS and ABS find occasional appli ions in wood composites. Composites contain both wood fibers and wood flour. The wood fillers make up anywhere from 50% to 70% of a composite. Coupling agents are generally added at levels of 1% to 3% of the weight of the wood fillers. Maleated polyolefins are possibly the largest group of coupling …

Coupling Agent - an overview | ScienceDirect Topics Composites containing a coupling agent absorbed either 12% or 9% depending on the coupling agent used. However, the use of a lubricant as a processing aid negated any positive effect of the coupling agent. Lin et al. (2002) reported an 18% decrease in moisture absorption when 2% coupling agent was added to 15% wood flour filled PP composite

Wood-Filled Plastics: They Need the Right Additives for EBS with zinc stearate is widely used in wood-HDPE. However, there are new alternatives because metal stearates are known to decouple the maleic anhydride of maleated coupling agents, canceling the effectiveness of both lubricant and coupling agent. These new lubricants sell for around $1/lb vs. 70¢ to 90¢/lb for EBS and zinc stearate.

Coupling Agent - an overview | ScienceDirect Topics The addition of coupling agents increased wettability between the wood particles and the polymer matrix used, enhanced dispersion in the matrix, and improved adhesion in both components. Enhancing dispersion promoted the encapsulation of wood particles and the polymer matrix, thus reducing moisture and water uptake in the composites.

Coupling agents enhance performance of wood plastic composites Other coupling agents employed in wood-plastic composites include organosilanes, fatty acid derivatives, long-chain chlorinated paraffins, and polyolefin copolymers with acid anhydrides incorporated into the polymer backbones instead of grafted .
