For manufacturers producing PVC products intended for outdoor use, durability and resistance to environmental factors are non-negotiable. Chlorinated Polyethylene (CPE) 135A has become a go-to additive for enhancing these very properties. Its exceptional weatherability makes it a superior choice over many other impact modifiers and processing aids. NINGBO INNO PHARMCHEM CO.,LTD., a leading chemical supplier, details why CPE 135A is essential for your outdoor PVC applications.

Outdoor PVC products, such as window profiles, siding, fencing, and decking, are constantly exposed to a barrage of environmental stresses: UV radiation from sunlight, fluctuating temperatures, moisture, and pollutants. These factors can degrade the material, leading to discoloration, brittleness, and loss of mechanical integrity over time. The right additive is crucial to combat these effects.

Why CPE 135A Excels in Outdoor Applications:

  • Superior UV Resistance: CPE 135A exhibits excellent resistance to ultraviolet radiation. Unlike many organic polymers that degrade and chalk when exposed to sunlight, CPE maintains its structural integrity and color stability. This property is critical for maintaining the aesthetic appeal and functional performance of PVC building materials over years of sun exposure.
  • Ozone and Weathering Resistance: The saturated polymer backbone of CPE makes it highly resistant to ozone, a potent atmospheric oxidant that can cause cracking in unsaturated polymers. This, combined with its overall excellent weathering resistance, ensures that PVC products formulated with CPE 135A will endure harsh weather conditions without significant deterioration.
  • Temperature Stability: CPE 135A maintains good flexibility even at low temperatures while also offering adequate heat resistance. This broad temperature range stability prevents the PVC from becoming overly brittle in cold weather or softening excessively in warm conditions, contributing to the product's overall lifespan and performance.
  • Moisture and Chemical Resistance: The inherent inertness of CPE provides good resistance to moisture and various chemicals found in the environment, further protecting the PVC product from degradation and staining.
  • Impact Strength Retention: Even after prolonged exposure to outdoor conditions, CPE 135A helps retain the impact strength of PVC, preventing damage from accidental impacts or structural stresses.

Choosing CPE 135A for Your Outdoor PVC Products:

When you are looking to buy additives for outdoor PVC applications, consider the long-term benefits that CPE 135A offers:

  • Extended Product Lifespan: Formulations enhanced with CPE 135A result in PVC products that last longer, reducing the need for frequent replacements and maintenance.
  • Consistent Aesthetics: Products maintain their color and surface finish, crucial for maintaining curb appeal in architectural applications.
  • Enhanced Brand Reputation: Supplying durable, weather-resistant products builds trust and strengthens your brand's reputation for quality.
  • Cost-Effectiveness: While initial formulation might seem higher, the extended lifespan and reduced warranty claims make CPE 135A a cost-effective choice in the long run.
