CPE 135A Chlorinated Polyethylene: The Ideal Impact Modifier for High-Performance PVC Products
Release time:
2026-07-25
PVC (Polyvinyl Chloride) is one of the most widely used plastics in the construction, electrical, and industrial sectors. However, standard rigid PVC has limited impact resistance, especially in low-temperature environments. To improve its toughness and durability, manufacturers commonly incorporate CPE 135A (Chlorinated Polyethylene) as an impact modifier.
This article explains what CPE 135A is, its advantages, applications, and why it remains one of the preferred additives for rigid PVC products worldwide.
What Is CPE 135A?
CPE 135A is a chlorinated polyethylene resin produced by chlorinating high-density polyethylene (HDPE). With excellent compatibility with PVC resin, it significantly improves the impact strength and weather resistance of rigid PVC products without sacrificing processing performance.
As one of the most commonly used PVC impact modifiers, CPE 135A is widely applied in extrusion and injection molding processes for manufacturing high-quality PVC products.
Key Benefits of CPE 135A
Excellent Impact Strength
CPE 135A greatly enhances the toughness of rigid PVC, reducing the risk of cracking or breakage during transportation, installation, and long-term use.
Superior Weather Resistance
PVC products exposed to outdoor environments require excellent resistance to UV radiation, moisture, and temperature fluctuations. CPE 135A helps maintain long-term mechanical performance under harsh weather conditions.
Outstanding Low-Temperature Performance
Unlike standard PVC, formulations containing CPE 135A remain tough and resistant to impact even in cold climates, making them suitable for outdoor construction applications.
Excellent Processing Stability
CPE 135A disperses evenly in PVC compounds and offers stable melt processing, contributing to higher production efficiency and improved product consistency.
Cost-Effective Performance
Compared with many other impact modifiers, CPE 135A provides an excellent balance between performance and cost, making it a preferred choice for PVC manufacturers worldwide.
Typical Applications of CPE 135A
CPE 135A is suitable for a wide variety of rigid PVC products, including:
- PVC Pipes
- PVC Pipe Fittings
- PVC Window & Door Profiles
- PVC Electrical Conduits
- PVC Cable Protection Pipes
- PVC Foam Boards
- PVC Wall Panels
- PVC Decorative Profiles
- PVC Sheets
- PVC Building Materials
- Injection Molded PVC Products
- Extruded PVC Products
Its versatility makes it an essential additive for construction materials, infrastructure projects, and industrial applications.
Why Choose CPE 135A for PVC Compounds?
When selecting an impact modifier, manufacturers typically consider several key factors:
- Consistent product quality
- Easy dispersion in PVC resin
- Stable processing performance
- Excellent impact modification
- Long-term weather resistance
- Reliable supply and competitive pricing
CPE 135A meets these requirements while helping manufacturers improve product quality and production efficiency.
Storage and Handling
To maintain optimal performance, CPE 135A should be stored in a cool, dry, and well-ventilated environment. Keep the packaging tightly sealed to prevent moisture absorption and avoid prolonged exposure to direct sunlight.
Standard packaging is 25 kg woven bags with PE inner liners, making transportation and storage convenient for industrial users.
