Polybond 3200 coupling agent improves the tensile and flexural properties of an organoclay-polypropylene nanocomposite.
Samples tested here were prepared by direct blending all ingredients and compounding on a twin-screw extruder. Additional increases in properties are possible using a two step process in which a clay concentrate is first prepared and is then letdown to its final level.

The use of natural fiber-filled plastics in construction applications is prevalent in North America. Wood flour is the most widely used natural fiber in these applications.
In the automotive market, the Europeans have been quicker to adopt natural fibers like Hemp, Flax and Kenaf as means of conserving resources, reducing weight and saving money.

22. 40% Wood-filled HDPE Effect of PB 3009 Level on Flexural Properties
This slide shows the effect of PB3009, a MA-HDPE coupling agent, on flexural properties. In this study, PB levels of , 1.0, 1.5, 2.5, and 4.0% were evaluated. Both unaged and moisture aged FS increased with increasing CA level. Unaged modulus was essentially independent of CA. However, modulus retention after moisture aging was better at higher PB levels.
Tensile properties showed similar results to the flexural data shown here. Tensile strength before and after moisture aging increased as the CA level increased. Unaged Tensile modulus was independent of PB level but retention of modulus after moisture aging was improved by the coupling agent.
Impact properties also increased as the level of the coupling agent was increased.
These unaged data can be explained as follows. It is well known that CAs improve interfacial adhesion between fiber and polymer matrix. Modulus measurements are low strain tests which don’t stress fiber-resin interface. Effects of improved interfacial adhesion produced by CA only seen in tests such as flexural, tensile, impact strengths where inelastic flow or fracture take place.
Improvements in the properties after moisture aging are related to reduce water absorption which will be shown in the next slide.
