Five layers co-extrusion technology
Qingzhou Luguan Plastic Factory took the lead in introducing 5 sets of imported five-layer equipment in China in 2015. In 2017, Luguan added two new five-layer equipment. In 2020, a five-layer co-extrusion equipment with German technology (56 meters in height) ), it can produce 21 meters wide PO film. It is currently the earliest and most domestic manufacturer with five-layer equipment.
Three-layer co-extrusion due to the small number of layers, in the production process, some different additive functions are mixed in the same layer. And some additives may influence and conflict with each other due to their own structure, and finally each function affects each other, and cannot play their best advantages.
The five-layer co-extrusion technology can add a variety of materials to the resins or additives of different layers, enabling multiple layers of materials with different characteristics to be compounded with each other during the extrusion process, and because each layer is independent, it is not There are mutual influences, so that the product has the excellent characteristics of a variety of different materials, and complements each other in characteristics, so that a variety of properties can be combined to achieve the best balance.
Compared with the products produced by the three-layer co-extrusion technology, the five-layer co-extrusion production technology can ensure the product's light diffusion effect, heat preservation function, anti-fogging function, anti-ultraviolet aging stability, UV radiation resistance, no dripping, and dustproof With stronger functions and higher stability, the product has a more adequate guarantee for the balance and realization of multiple functions.
The five-layer technology is perfectly combined with the PO technology. The 5+1 PO film launched by Qingzhou Luguan in 2015 has better performance than the three-layer product in terms of transparency, strength, heat preservation, and dust resistance. The leap has been widely praised and recognized by the market.
