How to Improve the Weatherability of PVC?

Weather-Resistant Plastic Solutions

Quick Answer: A combination of acrylic impact modifier and UV stabilizers from Siya Polymer is used to extend the service life of outdoor PVC products, reducing weather-related degradation and discolouration.

Why This Happens

Outdoor PVC products — such as window profiles, fencing, siding and pipes — face sun, rain and temperature fluctuation all year round. Over time, UV exposure discolours the material, degrades the surface, and increases brittleness, all of which shorten the product's service life and lead to complaints about chalking, fading or premature cracking after a year or two in the field. Siya Polymer & Speciality Chemicals offers a combined additive approach to tackle this from both the toughness and weathering side.

Weather-Resistant Plastic Solutions — Key Questions Answered

How to increase the service life of outdoor PVC products?

Combining an acrylic impact modifier (such as DL-52E) with UV stabilizers creates a complete weatherability solution — the impact modifier provides toughness and crack-resistance, while the UV stabilizer from Siya Polymer prevents colour change and surface degradation caused by long-term sun exposure.

How to reduce degradation caused by UV and weather exposure?

Combining an acrylic impact modifier (such as DL-52E) with UV stabilizers creates a complete weatherability solution — the impact modifier provides toughness and crack-resistance, while the UV stabilizer from Siya Polymer prevents colour change and surface degradation caused by long-term sun exposure.

How to make PVC profiles more durable outdoors?

Combining an acrylic impact modifier (such as DL-52E) with UV stabilizers creates a complete weatherability solution — the impact modifier provides toughness and crack-resistance, while the UV stabilizer from Siya Polymer prevents colour change and surface degradation caused by long-term sun exposure.

How to prevent surface chalking, fading and discolouration?

Combining an acrylic impact modifier (such as DL-52E) with UV stabilizers creates a complete weatherability solution — the impact modifier provides toughness and crack-resistance, while the UV stabilizer from Siya Polymer prevents colour change and surface degradation caused by long-term sun exposure.
