ASA–PVC Co-Extrusion for Roofing: Practical Application Guide

When it comes to roofing, durability and long-lasting appearance are key. That’s why more producers are turning to ASA (Acrylonitrile–Styrene–Acrylate) granules in co-extrusion with PVC.

At WEIFANG VIKEM, our ASA materials are designed to deliver:

• Weather resistance – keeping color and gloss stable under strong sunlight and changing climates.

• UV protection – extending the service life of roofing sheets without fading or chalking.

• Impact strength – reducing the risk of surface cracks or damage during installation and daily use.

• Chemical resistance – helping the roof withstand rain, dust, and cleaning over time.

Why ASA–PVC Co-Extrusion Works for Roofing

In this process, ASA becomes the protective outer layer, while PVC provides structural strength and cost efficiency underneath. The result is roofing that looks good, performs well outdoors, and offers a solid balance between performance and affordability

As a source manufacturer of ASA granules and PVC additives, we don’t just supply raw materials – we also share processing know-how and support. Our goal is simple: help our partners make roofing products that last longer and win in the market.
