01. Plastic alloy
The compatibilizer plays a good role in adjusting and controlling the microscopic phase structure of the alloy technology, so that the blend material can achieve high performance and functionalization. Compatibilizers are widely used in PP/PE, PP/PA, PA/PS, PA/ABS, ABS/PC, PBT/PA, PET/PA, PP/POE, PE/EPDM, TPE/PU and other alloys.
02. Polymer modification
Because the compatibilizer is a "bridge" between the non-polar and polar polymers by the carboxyl group of the active free radical molecule, it is modified into a polar polymer, and then blended with the polar polymer, and the reaction between the two is carried out to obtain a good modification and blending effect.
03. Recycle waste plastics
The use of compatibilizers to recycle waste plastics and make them into new plastic alloys or new modified plastics is a good and feasible method for "comprehensive utilization of waste", and can solve the problem of "white pollution", which has great social and economic benefits for enterprises. There are many precedents in foreign countries, such as the BENNET compatibilizer produced by the Dutch * mining company, which is a special compatibilizer for the recycling of waste plastics, which can be blended and recycled with two or more different varieties and different properties, such as polyolefin plastics and engineering plastics, and add 5%-10% compatibilizer as the interface layer between the sea phase or island phase, and give full play to the bonding force polar compatibilizer efficiency, and prepare a new plastic alloy or modified plastic.
04. Coupling of plastics and fillers
Compatibilizers are also known as macromolecule coupling agents. Because it is compatible with polymer polymers, the compatibilizer has excellent coupling efficiency between plastics and fillers, and can be used for PE/CaCO3, PE/talc, PA/GF and other coupling treatments, with good results.
05. Toughening of polar resins
Thermoplastic elastomer has good softness, high elasticity and low temperature properties, and adding a certain amount of compatibilizer can be used as a toughening agent for PP, PE, PS, PA, PC and other plastics. The compatibilizer is the most critical "core" and "shell" compatibility of these tougheners. For example, MAH grafted EPDM toughening agent can maintain excellent physical properties and toughness at a temperature of -45 °C. The general dosage is 5%-10%.
06. Improve other properties of plastics
Compatibilizers can also be used to improve the adhesion, antistatic, printability, gloss and other properties of plastics.
