Descrizione dei prodotti
W5B è un polimero ad innesto contenente un gruppo funzionale glicidil estere, elastomero poliolefinico come materiale di matrice, ad alta reattività e basso residuo.
Because good elastomers dispersion and acceptable interfacial adhesion may be produced concurrently, the examination of the toughening process revealed that a suitable compatibility was crucial for producing supertough PBT blends. Too much interfacial adhesion prevented interface debonding and stopped matrix shear yielding, whereas the weak interface and high particle size caused unstable crack propagation. The primary toughening mechanism in toughened PBT blends was microvoiding produced by both the debonding and internal cavitation of elastomers, followed by matrix shear yielding.
W5B is a graft modifier that has high elasticity and may be used to boost adhesion to metals and other polar substrates or to improve compatibility between polar and non-polar polymers. conforms to requirements for interaction with food.
W5B is a graft polymer that has a glycidyl ester functional group and is incredibly inventive and adaptable. It is made with a polyolefin elastomer, which offers exceptional flexibility and durability, as the matrix material. W5B has outstanding features, including strong reactivity and little residue, thanks to this rare combination of components.
W5B’s strong responsiveness is one of its main benefits. The rapid crosslinking processes made possible by the glycidyl ester functional group allow the polymer to create solid and durable connections with other substances. W5B is useful for a variety of applications where adhesion, bonding, or coating qualities are needed because to its reactivity.
In the automobile sector, it is mostly used to alter and toughen PP, PE, and PA to manufacture bumpers, fenders, steering wheels, gaskets, and other items.

The following table shows that increasing the amount of W5B by 4% in the PBT flame retardant reinforcing system can increase the notched impact strength while maintaining other attributes. It demonstrates that W5B has higher processing capabilities in PBT flame retardant reinforcement systems and can aid in the uniform dispersion of glass fiber and flame retardant.
Caratteristica
W5B è adatto per prodotti che richiedono un'elevata reattività e un basso residuo.
- W5B has great adaptability thanks to the special union of the glycidyl ester functional group and the polyolefin elastomer matrix material. It is simple to alter or combine with other polymers to modify its characteristics to meet the needs of a particular application. This adaptability enables the creation of specialized solutions that address the various demands of various sectors.
- According to the characteristics of different engineering plastics, the basic resin and grafted functional groups of the toughening agent are selected in a targeted manner. W series products are mainly used as polyester tougheners or compatibilizers, which can effectively disperse in engineering plastics to form micro-rubber phases, improve the compatibility between different phase interfaces of polyester alloys, thereby increasing the impact resistance of engineering plastics, Expand the range of material applications.
