UV & Weathering Protection for Plastics

Protect Plastics from Sunlight, UV Exposure and Outdoor Ageing

Sunlight and outdoor exposure can gradually damage polymers, leading to discoloration, surface cracking, brittleness, loss of mechanical properties and reduced product lifetime.

Polymatica provides UV stabilizer masterbatches and weathering protection solutions designed to improve the durability of plastics used in outdoor and light-exposed applications.

PP | PE | Recycled Plastics | Films | WPC | Outdoor Components​

What Causes UV Degradation in Plastics?

Ultraviolet radiation from sunlight can initiate chemical reactions inside polymers.

Over time, UV exposure may cause:

  • Polymer chain degradation

  • Surface cracking

  • Yellowing or color fading

  • Loss of impact strength

  • Reduced flexibility

  • Brittleness

  • Loss of gloss

  • Reduced mechanical performance

  • Shorter product lifetime

Outdoor products may also experience heat, moisture and oxygen, which can accelerate weathering and polymer ageing.

Common Signs of UV & Weathering Damage

Are you experiencing:

  • Color fading after outdoor exposure?

  • Cracking or chalking on the surface?

  • Brittle plastic parts?

  • Loss of flexibility?

  • Reduced impact resistance?

  • Premature failure of outdoor plastic products?

  • Poor durability under sunlight?

These problems may indicate that the polymer requires a more effective UV stabilization system.

UV Stabilizer Masterbatches for Plastics

Polymatica UVGuard™

UV Stabilizer Masterbatch for PP, PE and Outdoor Plastics

UVGuard™ is designed to help protect plastics from UV-induced degradation and improve long-term outdoor durability.

Key Benefits

  • Helps reduce UV degradation

  • Supports longer outdoor service life

  • Helps maintain mechanical properties

  • Helps reduce premature brittleness

  • Supports color and surface stability

  • Suitable for virgin and recycled polymers

  • Easy-to-use masterbatch format

Polymatica UVGuard™ HALS

HALS Masterbatch for Long-Term Light Stabilization

UVGuard™ HALS contains Hindered Amine Light Stabilizer technology designed to help protect polymers against long-term photo-oxidative degradation.

HALS systems are particularly useful in applications exposed to prolonged sunlight and outdoor conditions.

Suitable Applications

  • Outdoor PP and PE products

  • Agricultural plastics

  • Automotive components

  • Wood-plastic composites

  • Industrial plastic parts

  • Recycled polyolefin compounds

Polymatica UVGuard™ Absorb

UV Absorber Masterbatch

UVGuard™ Absorb is designed for applications where UV absorption is required to protect the polymer or sensitive components inside the material.

It can be considered for selected:

  • Films

  • Transparent plastics

  • Packaging applications

  • Light-sensitive polymer systems

UV Protection for Recycled Plastics

Recycled polymers may already have experienced previous thermal, oxidative and environmental ageing.

When these materials are used again in outdoor applications, an optimized UV stabilizer package can help improve durability and reduce premature failure.

Depending on the formulation, recycled plastics may require a combination of:

UV stabilizer + antioxidant + processing stabilizer

to achieve better long-term performance.

Applications

Outdoor Plastic Products

Improve resistance to sunlight and environmental exposure.

Automotive Plastics

Protect exterior and selected interior polymer components from UV-induced ageing.

Agricultural Plastics

Support durability of polymer products exposed to prolonged sunlight.

Wood-Plastic Composites

Improve weathering resistance in PP- and PE-based WPC formulations.

Films & Packaging

Provide UV protection for selected film and packaging applications.

Recycled Plastic Products

Improve outdoor durability of recycled PP and PE compounds.

UV Stabilizer, HALS or UV Absorber?

Different applications require different stabilization strategies.

UV Stabilizers

Designed to reduce the harmful effects of UV exposure on polymer performance.

HALS

Help interrupt degradation reactions caused by light and oxidation.

UV Absorbers

Absorb harmful UV radiation before it can significantly damage the polymer or sensitive components.

The best system depends on:

  • Polymer type

  • Product thickness

  • Outdoor exposure time

  • Climate

  • Color

  • Processing conditions

  • Required service life

  • Final application

Polymatica can help determine the most suitable stabilization strategy for your material.

Customized UV & Weathering Solutions

Every Outdoor Application Is Different

A plastic product used outdoors in Québec may experience very different conditions from a film, automotive component or agricultural product.

Tell us:

1. Which polymer are you using?

2. Is the material virgin, recycled or blended?

3. Is the product used indoors or outdoors?

4. How long should it remain stable?

5. What type of UV or weathering damage are you observing?

Polymatica can recommend an existing UV stabilizer masterbatch or develop a customized stabilization package.

Improve Outdoor Durability and Polymer Lifetime

If your plastic is fading, cracking, becoming brittle or losing performance under sunlight, the stabilization package may need to be optimized.

Tell us about your polymer, application and exposure conditions.
