How to Reduce Brittleness in PVC Products?

PVC Impact Modification Solutions

Quick Answer: Using an acrylic impact modifier such as Siya Polymer's DL-52E in PVC profiles, fencing and siding reduces brittleness and improves both impact resistance and weatherability.

Why This Happens

PVC is an inherently rigid and brittle polymer, and this brittleness becomes even more visible in outdoor products like profiles, fencing and siding, where temperature swings and UV exposure make the material harder and more prone to failure over time. Without proper impact modification, PVC products carry a real risk of cracking during transport, installation or extreme weather — leading to costly site rejections and warranty claims. Siya Polymer & Speciality Chemicals specialises in solving exactly this problem for PVC profile, pipe, fencing and siding manufacturers.
