PMMA on PVC Substrate Co-extrusion Construction Profiles



Lumei has been in UPVC extrusion fields for more than 25 years. During the coextrusion process(PVC & PMMA), the PVC sheets are covered with a thin PMMA ultra-matt layer exhibiting the required high weather resistant & beautiful surface results. How did Lucite International achieve the right impact resistance and melt flow? This requirement is to improve the impact resistance while improving the melt flow (normally a higher impact resistance leads to a lower melt flow). To achieve this objective, Lucite International manufactured an impact modifier for use in conjunction with the PMMA material and specifically formulated this to give a higher melt flow and rheology suitable for coextrusion onto PVC substrate.










By doing this, Lumei Construction Material system provided a cost effective solution which did not involve any capital expenditure on new processing equipment to the customer, or require any further secondary processing operations.


Different colors for customized PVC & ASA co-extruded uPVC profiles. Since ASA has great color stable property, it help to used widely in its colorful surface.  About the Co-extruded color, we can match it by Panton or RAL color code or just a small pieces of sample. All the above color can be customized by Lumei uPVC profiles.
