the licocene pe ma and licocene pp ma series were specially developed as coupling agents and compatibilizers for natural fiber-filled composites. in wpc with polyethylene as the polymer ingredient, licocene pe ma 4351 tp is used. in wpc in which polypropylene is used as a polymer, meanwhile, clariant recommends licocene pp ma 6452 tp.
application: linewood additives are a range of coupling agents specifically deisgned for the wood plastic composite sector wpc . at low dosages, the linewood range greatly improves dispersion of wood flour or vegetable fillers of various kinds of polyolefinic matrices pp or pe while enhancing the aesthetic and mechanical properties of the finished product.
alibaba.com offers 117 wpc coupling agent products. about 27% of these are plastic auxiliary agents, 1% are leather auxiliary agents, and 1% are electronics chemicals. a wide variety of wpc coupling agent options are available to you, such as plastic auxiliary agents, coating auxiliary agents, and rubber auxiliary agents.
lubricants and coupling agents. two kinds of lubricants are often used in wpc and in extrusion in general: external and internal lubricants. the external lubricants improve the surface quality and lead to higher output rates as friction goes down during the extrusion process.
coupling agents are used in combination with other additives. among them are lubricants, heat stabilizers, light stabilizers, colorants, biocides and foaming agents. sometimes these additives have antagonistic effects - some lubricants, for example, tend to interfere with coupling agents.
concentration of coupling agents had a signicant effect on the interfacial bonding in wpc. the coupling agents with a high molecular weight, moderate acid number, and low concentration level were preferred to improve interfacial adhesion in wpc. the backbone structure of coupling agents also affected the interfacial bonding strength. com-
coupling agents. in order to compensate for the lower mechanical strength when compared, for example, with metal, these plastics are reinforced with fibers. the better and the more evenly these fibers are incorporated into the polymer matrix, the greater the performance of the reinforced plastic and its mechanical properties.
a silane coupling agent will act at an interface between an inorganic substrate such as glass, metal or mineral and an organic material such as an organic polymer, coating or adhesive to bond, or couple, the two dissimilar materials. a simplified picture of the coupling mechanism is shown in figure 1. figure 1. the silane coupling mechanism.
slane coupling i agents silane coupling agents have the ability to form a durable bond between organic and inorganic materials . encounters between dissimilar materials often involve at least one member thats siliceous or has surface chemistry with siliceous properties; silicates, aluminates, borates, etc .,
the main applications of kayabrid are: glass fiber reinforced polypropylene gfrpp , wood-plastic composites wpc and high-loaded halogen free flame retardant hffr cables. performance. the graph below shows the efficiency of kayabrid compared to conventional coupling agents. the performance is confirmed by many customers reporting:
other coupling agents. effect of coupling agents on mechanical properties of woodplastic composites: experimental data. mechanisms of crosslinking, coupling and/or compatibilizing effects. effect of coupling agents on wpc properties: a summary. lubricants, compatible and not compatible with coupling agent. references
the catalysts, coupling agent and accelerator were used as received. preparation of wpc the wpc were prepared by a two step procedure. the wood fibres were coated with coupling agent, then monomer was forced into the pores and polymerized using the catalyst-accelerator method.
results show that coupling agent 2 was superior to coupling agent 1 and had great effect on the physical and mechanical properties of wpc. when using the same coupling agent, the impact on their properties varied with different thermoplastic polymers.
though the function of a compatibilizer and a coupling agent is the similar of bringing the components closer to one another, the usage of this terminology is not common in the case of composites.
wpc with coupling agent has better mechanical properties such as flexural modulus than that without coupling agent. in case of impact strength, that of wpc with coupling agent decreases compared with that of wpc without coupling agent. between wood fiber and resin, interaction force of wpc without coupling agent is small. when wpc is impacted,
lubricants and coupling agents two kinds of lubricants are often used in wpc and in extrusion in general: external and internal lubricants. the external lubricants improve the surface quality and lead to higher output rates as friction goes down during the extrusion process.
