Application areas

331 series is the company's automotive decorative bright strip, the surface of non-polluting self-adhesive protective film products, mainly for the co-extrusion method of self-adhesive protective film applications, can also be used for the production of cast self-adhesive protective film, cotton wrapping film applications with excellent results.

 

Processing guidelines

● The reference setting temperature for pure 331 series extruder: 90℃-165℃ for extrusion section, 150℃-165℃ for die head, please adjust according to the actual situation of your own equipment and substrate formula for different manufacturers' co-extrusion film blowing units;
● The viscosity of the protective film can be adjusted by controlling the thickness of the adhesive layer or by co-extruding with other polyolefins, and the temperature of the extruder and die head should be adjusted appropriately according to the different types of materials, fluidity and processing temperature;
● To ensure smooth production and to avoid clogging of the extruder's downcomer (high melting temperatures leading to clumping of the sticky material), the temperature of the inlet must be kept below 70°C. It is recommended to use a downcomer with cooling water, especially in summer!
● The customer can adjust the formulation of the adhesive layer and the base material according to the actual application of the protective film to meet the end customer's needs;
● Customers who use their own products and require technical support can consult our staff.
